iStill Innovation: Reflux Capacitor!


Today, we introduce another iStill Innovation: the Reflux Capacitor! The Reflux Capacitor increases the performance of your iStill. Wanna find out more? This post dives in deeper … say … back to the future kinda deep?

What it does

The iStill Reflux Capacitor boosts the ABV that enters your column. Higher proof gases lead to a more stable and faster run. The output rates increase with around 25%, translating to around 2 hour faster run times and/or a higher ABV, depending on what your goal is.

In column mode, the iStill produces at a fixed ABV or proof. During the run the yield per hour drops to compensate for an ever lower alcohol strength boiler charge. With the iStill Reflux Capacitor, the column is fed with higher proof alcohol, resulting in up to 25% more output and a related decrease in run time of up to two hours. Here is a graphical representation of the extra performance the Reflux Capacitor gives:


In potstills, the output in liters per hour is pretty stable. Contrary to column distilling, the ABV or proof gradually decreases during the run. In potstill mode, in combination with the Reflux Capacitor, the strength of the output of your iStill increases by around 25%, decreasing run times with 25%, while mitigating the need for an additional, second or double, distillation. Please see the graphical explanation underneath:



Especially combined with ABV Control (for more reading, see:, the all new iStill Reflux Capacitor has huge benefits. Its applications? Here we go:

  1. Faster runs (up to 25%) in both column mode and potstill mode;
  2. Ultra-pure vodka and GNS hearts, with smaller heads and tails cuts;
  3. One distillation run on flavor rich products like brandy, rum, and whisk(e)y;
  4. No more need for double or 1.5 distillation approaches on flavor rich spirits;
  5. Instead, very efficient and taste rich single distillation approaches are now possible;
  6. Tails are pushed back, resulting in a bigger hearts yield;
  7. Further improved heads compaction;
  8. The Reflux Capacitor is made out of copper so it helps catalyze sulfur rich washes.

Roll-out and pricing

The new Reflux Capacitor can be ordered right now. We’ll add it to the iStill Online Design Center in the coming days. The Reflux Capacitor is available on all new orders for iStills 100, 500, 2000, and 5000. The Reflux Capacitor can be retrofitted to all NextGen iStills 500, 2000, and 5000.

The costs are as follows:

  • iStill 100 Reflux Capacitor: EUR 250,-;
  • iStill 500 Reflux Capacitor: EUR 450,-;
  • iStill 2000 Reflux Capacitor: EUR 650,-;
  • iStill 5000 Reflux Capacitor: EUR 850,-.

iStill 100 with potstill column!

We are currently doing a test run on the iStill 100 with potstill column for one of our UK customers. At full power, after only 49 minutes of heat-up time, it started producing an amazing 15 liters of spirits per hour! The need for cooling water during the distillation process? Only 2.9 liters per minute.

iStill Leasing Now Available in the EU!

When you buy iStill equipment, you already had the option to lease. At least in North America and in the UK. We now extend leasing to the EU. So if you are a craft distiller from a EU country, looking to lease your iStill Distillery, just send us an email and we’ll help you out.

Here are two examples of lease tariffs:

  • A base model, 25k iStill 500 would cost around EUR 532,- per month during 5 years;
  • A base model 40k iStill 2000 would cost around EUR 851,- per month during 5 years.


iStill Innovation: ABV Control!


Today, we help take the craft distilling industry take another leap forward. How? By introducing a new and amazing innovation called “ABV Control”.  This iStill Blog post will explain what it is and how it helps you out.

Traditional pot distilling and column distilling

Traditionally, pot distilling is the best approach to most flavorful spirits. Brandy and Cognac are distilled in a potstill, and so is single malt whisky. The advantage of pot distilling is that you work with batches. Batch-wise production allows the craft distiller to cut for heads, hearts, and tails, giving him control over the endproduct’s flavor composition. Also, the relative crudeness of this old design enables many flavors to come over in the end product. Downsides can be that heads and tails cuts translate to alcohol losses, and that a double distillation is needed to get the drink to proof.

Tall columns have always been used for vodka making. They hit 190 proof and that is it. Or a lower proof when tuned down to less tall columns. Batch (as the typical fruit brandy still) or continuous (as the now often used continuous strippers used in Bourbon production) approaches are possible.

Taste-wise, a potstill is amazing for pulling over flavors, where columns distill either very pure at high proof, or at lower ABV with compromises in cuts (on a continuous still) or early tails smearing (fruit brandy still). Technically,  a potstill has a steady output and a dropping alcohol percentage during the run, where column stills have a steady alcohol percentage at the cost of dropping yield. Like this (yield in green, ABV in red):


The iStill solution

One unique feature of the iStills is that one machine, in fact one-and-the-same set-up, can perform both functions. One riser/column combination – together with our esteemed robot and computerized control – does it all. If you choose to run the iStill in potstill mode, you get, well, exactly a potstill run. The automation makes the unit work as a potstill. And if you want purity instead of flavor, you choose our program for pure distilling and – at the sacrifice of yield as the run goes on – you create 190 proof product. Very flexible, right? Right! And now we are taking it one big leap further!

iStill ABV Control

Our latest innovation allows the craft distiller to make any spirit at the exact strength he wants it to be. Do you want your whiskey to come over at 65%? Dial it in and iStill ABV Control will make sure it comes over at 65% … All … The … Time. Perfect for barrel aging. Or if you disagree and feel 62% is better, well, then just dial that in. A light rum that needs to come over at 88%? A corn whiskey at 180 proof? Go for it. You now can.

Any percentage you like your product to come over, the iStill will deliver within a plus or minus 1% threshold. No drop in ABV, like on a potstill. No compromises in taste, like one would have with traditional fruit brandy or continuous columns. No compromises in efficiency, like basically any other (traditional) still gives you.

The advantages of iStill ABV Control

The USP’s? Here they are:

  1. Efficiency: iABV Control means you can take your wash directly to finishing strength. No more need for a stripping run;
  2. Taste: Since you can now distill your final spirit directly from an organically active boiler charge, more flavor will come over with this one distillation approach;
  3. Yield: Higher reflux ratios towards the end of the run will push tails back and increase total hearts yield.


New iStills 100, 500, 2000, and 5000, purchased from now onwards, will be equipped with iStill ABV Control for free. Customers that already have 2018 and 2019 model year iStills 100, 500, 2000 and 5000 will be upgraded to iStill ABV Control automatically via the software update program for free as well.

This new iStill 5000 has ABV Control …

How to mash 1000 pounds of grain in the iStill 2000!

Hi Odin,

Received and installed the indirect heaters, thanks. They’re a huge improvement. I know you’ve started selling the iStill Masher, but we’ve had pretty good success with our iStill 2000 and our “iHopper”. I’ve attached a video.  

With this system, we have a hopper, a pneumatic vibrator on the frame for grain flow and a small grist hydrator at the bottom of the hopper as the grain goes in.  We can get 1,000 pounds of grain in our 2000 with this system in under 30 minutes with little to no clumping.  (We put the mirror on the ceiling to monitor the grain as it goes in).  Just thought I would pass this along for anyone struggling with getting 1000+ pounds into their iStill.
