Name, style, brew date, gravities, milestones, tasting notes — kept on this device, as many batches as you run. ABV computes live by the house formula, (OG − FG) × 131.25, with apparent attenuation alongside. Milestone dates compute from the brew day you enter. And the packaging gate is structural, not advisory: until two FG readings, taken days apart, agree, this log will tell you — in writing — that bottling is not blessed. Bottling onto live fermentation is how bottle bombs happen; the gate is the room taking that seriously.

New to brewing? Start with Luka.
Never brewed a batch, don't own a single piece of gear, not sure extract and all-grain are even different sports — good, that's the job you hand him. Tell Luka what you've got (or don't), what you like to drink, and how much patience and space you're working with; he turns those answers into a first path, a first batch, and company on brew day. The school sits one step below — the guided first batch, the batch log with its packaging gate, the scaler, the troubleshooter. That's the depth he draws on. Start with the conversation.
Courses and logs save on this device. The process here follows the house brain exactly — sanitation is the religion, gravity is the measurement, and homebrewing is a hobby for adults: personal use, never for sale, and never a still.
Four doors in
Pick the one that sounds like you — Luka takes it from there
I don't know what to brew
It's my first batch
My last batch tastes off
I've brewed plenty — what's a new style or technique?
Each door opens Luka with the context already loaded. He asks the quick questions, you answer what you can — partial answers are fine, that's most of brewing — and the two of you land on a first batch.

The calculator shelf
The brew-day math, with the formulas printedFour calculators that finish the set the batch log and the scaler started. Every one shows its formula on the card — no silent math anywhere in this room — and your inputs stay saved on this device, like the log's. Gravity is the density of the wort (the sugary liquid yeast ferments) against water; volumes of CO2 are the standard carbonation unit — how many volumes of gas dissolve in one volume of beer.
What went sideways
Pick the flavor in the glass
Diagnose first, prescribe second: the ranked cause, the fix for this batch where one honestly exists, and the prevention that keeps it out of the next one.
The off-flavor library
Ten faults, symptom first — the troubleshooter's reference shelfThe troubleshooter above works from the one flavor you name. This library is the full shelf to browse: each fault in plain words — what it tastes and smells like, what usually causes it, what to check, the fix for the next batch — and the honest line brewers actually need, whether this batch can be saved. Fault names follow the BJCP's fault vocabulary; causes and fixes are the standard published guidance (Brew Your Own's off-flavor library is the model), written in the room's words. When a card's answer matters to a batch you're holding, run it through Luka — he diagnoses from this same library.
And then, the room pours
The paths and the log are the work. The Board is where the batch gets its honest review and the next one gets its one change — one destination among several.
