Mashing and Beer Making with the iStill Extractor!

Yes, we can mash with the iStill Extractor! Another addition to its already amazing versatility. How? Well, put your cracked grains in the Extractor, then heat-up the water in the boiler of (in this case) the iStill 2000. Next step? Put the pump on and start extracting and converting those starches and tastes from the Extractor to the boiler.

When extraction is done, all (now converted) sugars are assembled in the boiler. Cool the wort, pitch the yeast, and start fermenting. Or … boil the wort, add hops, crash cool, and then add the yeast. Right, you can use the iStill Extractor now for the production of distillers beer as well as consumers beer! Here’s a short video of how it works. A video of us using a new pump to help us to further automate mashing / extracting procedures.

Utah and Napa, here we come!

Hi there!

A quick update from Amsterdam, where we are preparing the coming 4-day Certified iStill Workshops. Coming Saturday I’ll fly over to Salt Lake City to give a distilling course to 15 craft distillers from all over North America. And two weeks after coming back, we have two Amsterdam 4-day workshops, one after the other. Busy times at the iStill University!

Next course in the USA is in March. In Napa Valley … and at the Napa Valley Distillery. Great location given all the wineries around as well as all the excitement related to craft distilling. The Napa Valley Workshop will be from March 19th to 22nd. If you want more information, please reach out to or Jason for info, Veronika for registration.

More courses in the near future? Yeah, I expect us to do a training in Australia in a few months from now!

Regards, Odin.

iStill University Certified Workshops are rated 9.7 out of 10 and considered the best craft distilling educations in the world …


New Manholes for the iStill 2000/5000 Series?

Hi there!

I need your input and feedback here. We are considering putting glass manholes on the iStills 2000 and 5000. Both have a diameter of 40 centimeters. What do you think? Is this an improvement over the current model? Would you like to be able to look inside the boiler? Please let us know what you think!

Regards, Odin.

Mashing Tulip Bulbs with the iStill 2000!

“How about a challenge?”, Joris Putman said, “How about we mash tulip bulbs for my tulip vodka in the iStill 2000?”

“Sure, why not?”, was my answer.

“Well,” Joris replied, “the way I want to do it is with like 800 kilo’s of tulip bulbs vs. 1100 liters of water.”

And that is steep, folks! Very steep. With grain, a normal ratio is 1 kilo of grain vs. 4 liters of water. In the case of the Clusius Craft Distillers’ tulip vodka mashing, we were talking closer to a 1:1.3. A wash three time thicker than a normal grain bill mashing scheme.

Since there is only one way to find out if the iStill, with its amazing boiler design and jet propulsion agitator system, can do the job, well, we went ahead and just did it. With great success, I can say. Here are some pictures and movies to show you how the day went.

Setting up another Distillery in the UK!

Part of our team is currently in the UK, where we are setting up another big distillery. Here are a few pics of the assembly of an iStill 5000.
