See all five tools ↓
Five tools, one system: an app for your phone, a printable guide for the shed wall, two focused planners and the flagship workbook. All share the verified formulas behind the free calculators.
Distiller's Field Guide · €7.95
26 printable pages in metric and US editions: the lookup tables you reach for mid-run, and the worksheets you fill in with a pencil while your hands are wet.
Fermentation Planner · €9.95
A focused spreadsheet for the fermentation half: build the wash, dose the nutrients on schedule, and log gravity day by day until the numbers say finished.
Distillation Run Planner · €12.95
The distillation half: plan the fractions before you fire the boiler, log all 24 jars as they come off, then let the sheet total your cuts and compute the dilution.
Also on your phone · €9.95 (~$11)
The planners and the workbook live on a computer. Pocket is the same verified maths in your hand at the still: no signal, no account, no waiting for a page to load with wet fingers.
On the email list? Pocket Lite, the five-calculator edition, is free. This is the full version.
Pro Workbook · €24.95 (~$29) · the flagship
The site tells you how much water to add. Then the page closes and the number is gone. The workbook keeps everything in one place: plan the wash, dose the nutrients, track the fermentation day by day, plan the cuts, and log the finished run next to every run before it. Open it in a year and your whole distilling history is there.
One home screen: jump to any calculator, and watch your totals grow with every batch you log.
Dilution with OIML precision, proof, ABV from gravity, temperature correction, sugar wash, yield, cuts, blending, nutrients.
One row per run: wash, gravity, cuts, hearts strength. ABV and pure alcohol compute themselves.
Gravity readings over time with attenuation computed per row. Know when a wash is done, not when you hope it is.
Opens with a complete example batch on every sheet, start to finish, so nothing needs explaining twice.
Pure formulas: no security warnings, protected against accidental edits without a password, every constant sourced.
Real screenshots from the metric edition. Click any sheet to view it full size.
Batch Log · one row per run, ABV and pure alcohol compute themselves
14 sheets, one click apart
Yes. Every formula, the logs and the dropdowns import exactly; import steps are on the Start Here sheet. Sheets redraws the three charts in its own style, so give them a quick restyle if you want them matching.
Identical, including the OIML mass-balance dilution and the two-pass NBS temperature correction. If the site and the workbook ever disagree, one of them has a bug and we fix it.
Both are included: metric (litres, °C, kg) and US (gallons, °F, lb, fl oz, TTB proof gallons).
Free for life. Your purchase link always serves the newest version, and updates are announced on the email list.
Neither. Pure formulas, so no security warnings anywhere. Formula cells are protected against accidental edits, but without a password; it is your file.
14 days, no questions. If it does not earn its place in your workflow, reply to the receipt email.
The app, the guide, both planners and the workbook: every tool above, in every edition, for €30.80 less than buying them separately.
