33 Questions on Taste-Rich Distilling
A free, no-nonsense guide written by Odin, founder of iStill, that explains what actually shapes flavor and where most distillers go wrong when it comes to fermentation, cuts, and still design.
Challenge your beliefs:
- Why 80% of flavor is created before distillation even starts
- What most people misunderstand about cuts
- Why copper isn’t the magic people think it is
- How still design really affects taste (and when it doesn’t)
- The small mistakes that quietly ruin good spirits
"Super fun read that I finished in an evening, can't look at distilling the same anymore".
"I recommend everyone I know to read this. It's great both for starters and for master distillers".
"Expected it to be long and boring, but its fun and easy to read!"
"Great kickstarter for the iStill course".
Build to last
The strongest unit on the market.
The iStill Fermenter is manufactured from 4 to 5 mm thick stainless steel sheets, where others use 0.7 to 1.7 mm only.
That difference puts it closer to production hardware than lightweight tank furniture, which matters when you need stable performance for years instead of a few seasons.
Efficiency
The most efficient unit on the market.
Its compact design, insulation, and total process control reduce wasted energy, keep fermentation behavior more stable, and create more predictable distillation inputs downstream.
Why it matters
The future of fermenting. Today.
Versatility.
The iStill Fermenter can help make any drink, from whiskey to rum, from vodka to brandy. It offers total control over both alcohol production and flavor production.
Build to last a lifetime.
iStill's Fermenters are made from high-quality stainless steel. It is strong, chemically inactive, and up to three times thicker than traditional mashers, boilers, and fermenters.
Business focus.
Spirits production should not consume all of your attention. Automation helps you spend less time on repetitive process work and more time on sales, story, and market building.
Complete control
Intelligent automation
The automation and robotization in the iStill Fermenter give you total control over the fermentation process. This helps you make the exact same top-shelf product over and over again.
Every setting, every stage, every second is monitored. The machine manages temperature precisely, while optional pH and remaining specific-gravity control can add another layer of repeatability.
Efficiency
Energy efficiency
The advanced design is over 90% efficient in its energy use. This lowers variable production costs significantly.
A compact footprint, insulation, and batch-built manufacturing help keep both operating cost and initial investment under control without compromising on vessel strength.
90%+energy efficient design
Built to keep heat where it belongs and reduce wasted energy across long production cycles.
Rethinking design
Square is the new round
Our patented flush square boiler offers unique properties. Mixing does not create agitation, so no new oxygen is introduced. Oxygen introduction stops the alcohol production process.
The iStill Fermenter is the only unit on the market that can mix during fermentation without introducing new oxygen. Another benefit is an ultra-high, over 90% fill grade.
Sizes
Production-ready fermenter sizes.
These are the two classic production sizes featured on the legacy product page. The current design studio can take you deeper.
