Still Design: Why Air Resistance Matters!

Introduction

Air resistance is important when designing a car or parachute, but for a still? Really!?! Yes, it is. Distilling is all about managing and manipulating the vapors that rise from the boiler. The amount of resistance, that the rising vapors encounter, influences the speed of those vapors. And vapor speeds define flavor composition.

Okay, maybe we should call it vapor resistance, rather than air resistance, but it got your attention, right? And it is basically the same thing. Interested to learn more? You better be. Managing vapors successfully is what is required to become recognized as a skilled distiller, so let’s dive in deeper.

Cuts for flavors

Have you ever noticed how a fast stripping run isn’t ideal for making cuts? How, for your cuts to work out, a lower power setting usually works better? Cutting is about the master distiller deciding what flavors should be in the spirit and what flavors should be cut out.

Heads, hearts, and tails

As we saw in an earlier iStill Blog post, flavors associate with heads, hearts, and tails (for more reading, please see: https://istillblog.com/2021/06/10/whos-afraid-of-heads-hearts-and-tails/). Fruity flavors come over during the beginning of the run, followed by the hearts-associated substrate flavors. At the end of the run the earthy and rooty tails-associated flavors come over.

Since, during the distillation run, the original alcohol charge in the boiler is slowly depleted, the rising vapors will become less alcohol rich and more water dense. As a result the temperature of the gasses increases (water boils at higher temperatures than alcohol). The iStill takes advantage of this by having an extensive control and management system in place, that allows the distiller to cut consistently each and every time, given a certain power setting. It is the “given a certain power setting” part that I now want to draw your attention to.

Vapor speeds, separation, and smearing

Our stills are insulated. Therefore an increase in power results in the creation of more gasses and more product per minute or hour. Since the column and boiler are structural parts that do not all of a sudden change shape or size, that column – with a power increase – needs to process more gasses. A higher power setting will result in higher vapor speeds in the column.

Low boiling point alcohols (and their associated fruity flavors) come over during the early part of the run. They need relatively low energy settings to boil off. High boiling point alcohols (and their associated rooty, nutty, and earthy flavors) come over later in the run. These molecules need relatively high energy settings and higher vapor speeds to come over.

With the above in mind, now imagine that we do a slow run. The headsy factions boil off first, since they need the lowest amount of energy and the lowest vapor speeds to come over. When almost all the heads is gone, the transition towards hearts collection takes place. And when almost all the ethanol (and its associated substrate flavors) is gone, the tails slowly and gradually blend in.

Now imagine a fast run instead. A high power setting results in higher vapor speeds. The higher vapor speeds push hearts and tails into the first faction of the run. As a result heads aren’t separated and depleted. During a very fast run, like a stripping run, the whole batch is smeared and tainted with heads, hearts, and tails. No separation, so not a great flavor. Quick and dirty. Do you see how vapor speed is essential to the amount of heads and tails we smear into hearts, and therefore how essential vapor speed is to flavor composition? If you do, let’s continue with the next chapter!

Vapor resistance hampers run consistency

Consistent vapor speeds are essential for consistent flavor harvesting, which is essential for consistent spirit production. You want your whiskey, rum, or gin to taste the same, each and every production run, right? Resistance in the vapor path not only leads to inefficiencies, it also results in vapor speed fluctuation. And if you have read the above paragraphs carefully, you now understand that vapor speed fluctuation is basically the same as flavor fluctuation. Flavor fluctuation prevents the craft distiller to produce high quality spirits consistently. Hence our efforts to design stills with the lowest possible internal vapor resistance. The less vapor speeds fluctuate, the less flavor fluctuation you’ll experience in the drinks you produce!

This is why air resistance matters. Resistance creates vapor speed fluctuation. Vapor speed fluctuation creates flavor inconsistency. Flavor inconsistency equals poor (or at least: suboptimal) quality. Poor quality impacts the craft distilling industry at large, and your personal business specifically. Poor quality destroys reputations as well as bottom-lines.

Do you want to become a better craft distiller? Do you want a better reputation and a better bottom-line? Control your vapor speeds. And ask your equipment supplier what he has done, design-wise, to give you that control. “What did you do to prevent vapor resistance?”, “How does the technology you provide limit vapor resistance as much as possible?” are legitimate questions any still manufacturer should be able to answer. Only they don’t and they can’t. We do, and here are some examples of how iStill gives you total control over vapor speeds and associated flavors via vapor resistance reduction.

Wide boiler design

Given a certain boiler charge volume, a still designer can decide to make a tall and narrow or a lower and wider design. A tall and narrow boiler dissipates its energy over a limited surface area. As a result the boil-up will be higher, creating turbulence in the vapor bath above the liquids. This inner-boiler turbulence results in the column or riser being fed with vapors at speeds that continuously change. The constantly changing vapor speeds in the column result in more smearing of heads and tails into hearts, and in less control over the exact amount of smearing.

A wider and lower boiler gives a much larger surface area (square root function!) for vapors to boil off from. As a result, there is less boil-up, and less turbulence. The column can now draw the vapors from a more stable gas bed, at steady speeds. Steady speeds result in less smearing and more control over the amount of smearing! iStill has a wider and lower boiler design, specifically for that reason.

Insulation

An uninsulated column creates a temperature difference between the outside and inside of that column. The colder environment cools the column. The cooler column liquifies rising gasses into (passive) reflux. This is more than just an inefficiency, because it also creates inconsistency.

An uninsulated column or riser results in passive reflux. Gasses that normally should have come over as product now fall back into the boiler. The colder the climate (or distilling hall) is, the more inefficiencies are introduced.

But an uninsulated column or riser is also a variable that boosts inconsistency. Cooler columns lead to more passive reflux and lower overall vapor speeds. Lower vapor speeds may make it difficult to create the right amount of smearing, for a certain product category. When the climate or temperature in the distilling hall changes, a bigger or smaller temperature differential establishes, resulting in lower or higher vapor speeds, and less control over flavor harvesting and reproducibility.

iStill insulates its columns to minimize the temperature difference outside and inside the column. A low to non-existent temperature difference leads to a more efficient run (less passive reflux), stable vapor speeds, and reproducible and consistent outcomes.

Inner column design

Let’s compare iStill’s perforated plate still with a traditional bubble-cap fruit brandy still. The traditional bubble-cap column has plates that hamper vapors, where our design allows vapors to pass through. Fruit brandy stills have sight glasses that stick out, generating vapor resistance in the column.

Traditional stills have dephlagmators that cool part of the gasses back to liquid state, depending on cooling management, coolant pressure, and coolant temperature, air pressure, and the differential between inner and outer column temperature. Their dephlags are designed with a limited number of through-tubes.

iStill designs its coolers with a maximized number of through-tubes. More surface area creates less turbulence. Less turbulence results in steady vapor speeds and consistent flavor profiles.

iStill doesn’t use dephlagmators and cooling management, but instead invented the column cooler and liquid management. These innovations have taken variables that influence resistance and vapor speeds out of the equation. Coolant pressure, temperature, air pressure, and the difference between inner and outer column temperatures no longer screw things up.

If you didn’t yet know why you wanted an iStill, now you do.

Bubble-Cap Stills Suck at Making Whisky!

Introduction

There, I said it. I have long considered not writing this post, but the misinformation about this topic affects the craft distilling industry negatively. That needs to be amended. Sure, statements like this will make me some haters, but hopefully that will be compensated by more craft distillers now being able to make better choices. And more importantly: better whiskies.

In this iStill Blog post, I’ll first investigate what a whisky is, and what its flavor profile should be like. Then, I’ll dive into the bubble-cap still design and elaborate on its pro’s and cons. Finally, I’ll explain how the bubble-cap still design prevents the craft distiller from making great whisky.

What’s whisky?

“Whisky is a distilled spirit, made from grain, where one – while drinking it – can identify the grain the whisky is made from”. Don’t you just love the above definition? It so clearly explains everything a whisky needs to be. Made from grain. And with the flavor profile intense enough to allow the drinker to establish the exact grain base. A spicy whisky? Probably rye. A sweet kinda whisky? Corn, so maybe a Bourbon. A mellow whisky? That must be a whisky made from wheat. A complex, full bodied whisky? I am putting my money on malted barley as its grain source.

Grain flavor profiles – and therefore whisky – are quite unique in that they offer front-of-mouth, middle-of-mouth, and back-of-mouth flavors. The floral and fruity flavors can be distinguished in the first second, where heads blend into hearts. The generic grain flavor hits you in the middle of the hearts cut, right after the headsy flavors subsided. The long finish reveals the tails-associated earthy, rooty, and nutty flavors. It is this long finish that is essential to whisky; essential to bringing out not only a long-lasting taste experience, but also the flavor identifiers for the grain bill.

What are the design pro’s and cons of a bubble-cap still?

A bubble-cap design is basically a potstill with two kinds of obstructions in the vapor path. First (from the perspective of the rising vapors), there are the plates with the bubble-caps on them. The gasses need to travel through them. Secondly, the vapors hit a cooler (that is often called a dephlagmator). The plates hamper the free flow of vapors. The cooler liquifies part of the vapors. The liquids fall back on the plates, creating a fixed liquid bath on ‘m. The gasses now have to almost fight their way upwards: through the plate, through the liquids, and through the cooler.

The benefits? Where a potstill can perform only one redistillation cycle, a bubble-cap plated still can perform multiple distillation cycles in one run. No more need for a stripping and finishing run! That’s great news. It helps with time and energy management.

The drawback? Those fixed liquid baths on top of the bubble-cap plates are tails traps. Now, mind you, this isn’t a drawback when producing fruit brandy. Fruit brandy focusses on heads associated flavors. For those fruity flavors to shine, tails smearing (with its heavier flavors) must be prevented. The bubble-cap still was invented for fruit brandy production. Bubble-cap stills offer a great defense against tails smearing. That was the real innovation they brought about, over a century and a half ago. Good for fruit brandy. Bad, really bad for whisky!

Why do bubble-cap stills suck at making whisky?

Bubble-cap stills suck at making whisky because they create two-dimensional spirits, drinks that high-light front-of-mouth and middle-of-mouth flavors. Whisky is (or should be) a three-dimensional drink, that offers a front, a middle, and (most importantly) a back-end.

Over 50% of the flavor is tails associated, is rooty, nutty, and earthy in make-up. It is that third and last dimension that makes or breaks a whisky. Try it. Drink some single malt. Wetten your mouth with a sip, then swallow. Keep your mouth closed. Now start counting. How long do you taste? Where do you taste it? A good fruit brandy is gone in seven seconds. A good whisky lasts and lingers in your throat for 15 to 25 seconds. The difference? Whisky has (or should have) a back-end, fruit brandy shouldn’t.

This is why bubble-cap stills suck at making whisky: they prevent the very flavors, that define any good whisky, from coming over into your spirit. Now that you know it, you can make better purchasing decisions, when starting-up (or reconfiguring) your distillery. Do you want to learn more about stills?

Who’s Afraid of Heads, Hearts, and Tails?

Introduction

Heads, hearts, and tails. Three simple words. But they inspire awe and fear in the hearts of many beginning distillers. Should we be afraid of heads, hearts, and tails? This iStill Blog post aims to answer that question in a few simple steps.

First, let’s investigate what heads, hearts, and tails are. Then, we’ll research their properties. As a third step, let us assess why heads, hearts, and tails are important – and often awe-inspiring. The final part of this blog post will propose a framework for you to manage heads, hearts, and tails cuts.

Heads, Hearts, and Tails: what are they?

Not al alcohol is ethanol and not all alcohol is created equal. Where ethanol is intoxicating without being toxic, when consumed in moderate amounts, some other alcohols are actually quite toxic, even when consumed in very limited amounts.

During distillation – especially in the lower power-input and higher-proof finishing runs – the good alcohol we call ethanol comes over in the middle, during the “heart” of the run. The other alcohols, with high toxicity, come over at the beginning and end of the finishing run. The first part of the run is therefor called “heads”, while the last part is named “tails”.

So basically heads and tails are phases during the distillation run, when overly toxic alcohols come over. Does it start to make sense why they are fear-inducing? Cut too many heads and tails into your hearts and you end up with a toxic spirit.

Okay, the bad news is that heads and tails are really bad. The good news is that they only come over in the beginning and at the end of the run, and the actual amounts are small. But what are their properties? Let’s dive in deeper.

Heads, Hearts, and Tails: what are their properties?

Scientifically, a better name for “heads” is “lower boiling point alcohols”. The alcohols with low boiling points come over early in the run. Think aceton or methanol. A better name for “tails” is “high boiling point alcohols”. Propanol, butanol, and furfural come over late in the run, because they boil off at very high temperatures. Higher than ethanol, and sometimes higher than water.

In general, low boiling point alcohols cause head-aches. High boiling point alcohols create stomach problems. Mnemonic? Heads give head-aches, where tails create tail-end issues.

Floral and fruity flavors come over during the first part of the distillation run. Floral and fruity flavors associate with heads. Rooty, nutty, and earthy flavors come over during the last part of the run and associate with tails. Do you feel a catch 22 coming? Here it is. If you want to cut out all heads, you’ll cut out all floral and fruity flavors as well. Do you want to get rid of tails? Great, stills (or run procedures) can do that for you. But you’ll loose all rooty, nutty, and earthy flavors as well.

Why are heads, hearts, and tails important – and awe-inspiring?

Cut in too many heads and you end up with a spirit that causes head-aches. Cut out too many heads and you end up with a spirit that lost its floral and fruity flavors. Idem for tails. Do you start to see why cutting for heads, hearts, and tails is important – and awe-inspiring at the same time? Good cuts make great product. Poor cuts destroy your product. In a way a good distiller is someone that knows how to make great cuts. In a way a great still is a machine that controls the cut-points for heads, hearts, and tails to perfection. In a way distilling comes down to cutting.

So far, the industry has seen two approaches on how to deal with this issue. Big Alcohol has often been accused to just cut everything in. It explains the morning-afters. It makes for a good amount of profit, since the manufacturer doesn’t have to cut out anything and all alcohols produced end up in a bottle. A bottle being sold to you.

The second school of thought, that started with the birth of craft distillation, aimed to cut out heads and tails all-together. The result? You can guess it, right? Uninteresting spirits.

Our insight, based on science, brought a third way of looking at heads, hearts, and tails to the forefront: the one we shared above, where heads, hearts, and tails have both positive and negative properties. It’s not about cutting them in or out, it is about the flavor profile you want to high-light as a distiller, when producing a certain spirit!

A Framework for Managing Heads, Hearts, and Tails

First, decide what spirit you want to make and what the associated flavor profile is. Some examples? Here you go. Vodka aims for a minimal flavor experience at high purity, so you’ll want to cut out all heads and all tails. Less flavor, more purity, less toxicity. Whisky is flavorful and full bodied. Incorporate late heads and early tails, and only cut out the early heads and late tails. You’ll get all the flavor, while controlling – to an extend – overall toxicity levels. Fruit brandy? Fruity flavors are found in the heads, so cut out all the tails, and cut out only the very first bit of the heads.

Secondly, choose the right type of still. A potstill sucks at compacting heads and tails … and is therefor a great tool for whisky making, where you need both the late heads and early tails to smear into hearts. Bubble cap stills offer great defense against tails smearing, which makes them very well suited for fruit brandy production. iStills, with their elaborate control systems and automated cuts management, can make any spirit to perfection.

Thirdly, please understand that low and high boiling point alcohols (and their associated flavors) are developed during fermentation, not during distillation. Distillation is simply a way to control them. In other words: if you want to create a certain flavor profile, for a certain product, with a certain still, well, it actually all starts with your fermentation protocols! If you ferment in such a way that no flavors and no toxic alcohols are formed, you are already almost at vodka level purity, even before starting-up your still. That is great if vodka was your goal, but not so good when making whisky. The opposite holds true as well: a flavorful ferment is a great base for whisky making, but not for vodka production.

The fourth step should actually be the first step. Learn more about still design, about spirit flavor profiles, about how fermentation influences heads, hearts, and tails production.

Whiskey – What Equipment Do I Need?

Introduction

Planning a distillery can be daunting. What equipment do I need? A simple question, but there are so many answers that are rooted in even more considerations. This post is the fifth of a series called “What Equipment Do I Need?”. Each post highlights one consideration. This week? Whiskey! What equipment do I need to make whiskey?

Whiskey making process

There are basically three fundamental steps to whiskey making:

  1. Mashing;
  2. Fermenting;
  3. Distilling.

Mashing

Mashing is the process where grain starch is converted into fermentable sugars. It is done by putting the cracked grains with warm water and certain amounts of enzymes in a vessel. Mixing the concoction and carefully managing the temperature are critical. Since mashing takes 4 to 6 hours, you need but one masher.

Fermenting

Fermenting is the process where grain sugars are converted into alcohol and flavor molecules. It is done by adding yeast to the mash, and by carefully managing temperature and pH. The process takes about 4 to 5 days, so traditionally you need 5 or 6 fermenters.

Distilling

Distillation concentrates and selects the alcohol and flavors. Usually a double distillation cycle is needed. Since distilling takes about an 8 hour shift, traditionally two stills are needed. One for the first stripping run, another one for the second finishing run

iStill solutions

The iStills can basically mash, ferment, and distill. So one iStill (preferably as big as you can afford and house) is all you need. Let that sink in for a moment. And if you still want to go the traditional route of a separate masher, 6 fermenters, and two stills, well, we have these too!

Okay then, 6 steps …

Material – What Equipment Do I Need?

Introduction

Planning a distillery can be daunting. What equipment do I need? A simple question, but there are so many answers that are rooted in even more considerations. This post is the fourth of a series called “What Equipment Do I Need?”. Each post highlights one consideration. This week? Material! What will my still be made of?

Materials for still building

There are basically two materials a still can be build from:

  1. Stainless steel;
  2. Copper;

Each material has specific benefits as well as specific negatives. Time to find out more!

Stainless steel

As stainless steel is relatively affordable, stainless steel stills offer great value for money. Since this material is chemically very resistant, it has superior longevity. As a result of its resistance, it does not chemically interact with the spirits you are making, which has both positive and negative consequences. No contamination on the one hand, no sulfur catalysis on the other hand. Stainless steel stills can be fitted with a catalyst to manage sulfurs though. A final consideration? Some perceive a stainless steel distillery as modern looking, which can be both a pro and a con.

Coppper

As copper is expensive, both to purchase and to work with, copper stills are relatively expensive. Since the material is chemically very active, it offers limited longevity. A benefit from copper being very reactive, rather than inert, is that it catalyses sulfuric compounds that may have developed during (uncontrolled) fermentations. Without the iStill Copper Particle Filter, copper creates health risks in the spirits you produce. Many perceive a copper distillery as being more romantic looking, which can add to the artisanal experience that many distillers associate with being craft.

Copper vs. Stainless Steel …

Automation – What Equipment Do I Need?

Introduction

Planning a distillery can be daunting. What equipment do I need? A simple question, but there are so many answers that are rooted in even more considerations and assumptions. This post is the third of a series called “What Equipment Do I Need?”. Each post highlights one consideration. This week? Automation! What level of automation do I need?

Levels of automation

There are basically three levels of automation a distiller can choose from:

  1. No automation – subjective sensory assessments control the run and all work is done manually;
  2. Semi-automated – objective measurements control the run and all work is done manually;
  3. Automated and robotized – objective measurements control the run and the work is done automatically.

The higher the level, the more support and control you get. Let’s dive in deeper, so you can make a better judgement call on what you need!

No automation

Without automation, you will find it impossible to reproduce spirit profiles successfully. You’ll need extensive batch-mixing to create any level of consistency. Since all the work is done manually, your distillery need to invest in labor, which leads to higher staffing costs. iStill does not support this kind of operation, since we strongly believe that spirits reproducibility is conditional to becoming a successful craft distiller.

Semi-automated

A semi-automated still measures what goes on inside your still objectively. This allows you to reproduce spirit flavor profiles. Since the measurements result in manual actions, performed by your staff, you run the risk of introducing some proces-operator bias into your spirts, where the distillers preferences shine through, rather than yours. Because most of the work is done manually, you’ll still need to invest in higher staffing costs. iStill supports this level of automation via our semi-automated line-up of iStills.

Automated and robotized

A fully automated and robotized still measures what goes on inside your still objectively, and makes the associated cuts itself. This leads to your distillery being able to fully reproduce the exact flavor profile time and again. No risk of proces-operator bias. No need to invest heavily in additional staffing. You’ll produce the best quality spirits in the most reproducible manner, and in the most efficient way. iStill is the only distillery manufacturer that offers this level three automation and robotization to craft distillers.

Automation => Control => Quality …

iStill USP’s!

Introduction

By introducing innovative and disruptive new technology to the market, iStill aims to empower the craft distilling industry. But what does our technology give you? How do we empower craft distillers all over the world? Or – to put it in marketing terms – what are iStill’s unique selling points or USP’s? Let’s dive in deeper.

Reproducibility

More than any other still out there, iStills are designed with perfect process control in mind. Our focus on technologically advanced monitoring and management systems, allow the craft distiller to make the same product over and over again, while deleting the risk of output variability.

Quality

The total control over taste formation, concentration, and separation processes results in higher quality spirits. More flavorful whiskey, gin, brandy, and rum. More neutral vodka.

Efficiency

iStill’s application and incorporation of 21st century technology results in more efficient distilling. Operational costs of an iStill distillery are only about 25%, when compared to a traditional set-up.

Versatility

An iStill can make any product. Instead of having to invest into new equipment for each and every new spirit you want to release, our technology supports the production of any spirit, be it whisky, rum, brandy, gin, vodka, tequila, or liqueur.

Continuously

Our stainless steel stills don’t rust and deteriorate. Careful material selection and a focus on over-engineering, results in the industry’s best longevity and lowest down-time ratio’s.
