Most home and craft distillers run on a tangle of spreadsheets — one for wash logs, one for run notes, one for inventory, one for dilution math. Updates cascade by hand. The maths is fragile. Provenance is hope. Broover is the distilling workflow app that replaces the tangle with one connected system.
A typical distiller's spreadsheet stack has at least four tabs: wash log (date, sugar, yeast, OG, FG, notes), run log (strip run + spirit run + cuts), lot inventory (low wines, neutral, gin, vodka, rum on hand in litres and pure alcohol litres), and a dilution / ABV calc sheet for the bottling math. Each one references the others by hand. Update one row and you have to chase the cross-references manually. Misplace a column and lot provenance is gone.
It scales until it doesn't. Around the time you're juggling 8 active washes, 3 low-wines lots, and a couple of in-flight gin batches, the spreadsheet stops being a record-keeping tool and starts being a second job.
Wash log. Pitch a wash from a recipe — sugar bill, yeast, nutrient, OG target, temperature band all pre-filled. Log SG readings as the ferment progresses (manually, or automatically from a RAPT Pill / Tilt / iSpindel / Brewfather-connected device). Broover charts the ferment, predicts the ETA, and flags when the wash is done, stuck, or still going.
Run log. Strip the wash to a low-wines lot, spirit-run the low-wines to neutral, finish-spirit the neutral to bottled vodka / rum / whiskey / liqueur, or botanical-run for gin. Each run knows what wash or lot it came from; cuts and notes live with the run record.
Lot inventory. The dashboard sums every active lot — bottled gin, neutral on hand, low-wines waiting for the next spirit run — in litres and pure alcohol litres, live, no maintenance. Archive a finished lot in one click; it disappears from inventory totals but the provenance chain stays intact for the bottled spirits that depend on it.
Dilution + ABV math. Free distilling calculators in the browser — ABV from gravity (Hall formula, accurate across 5–25%), dilute-to-target with ethanol-water contraction correction (OIML R22 density tables), sugar bills, charge volumes, recovery prediction. No signup, faster than the spreadsheet you'd otherwise be hunting through.
Open a bottled gin lot in Broover and you see the chain that made it — back through the botanical run, the neutral lot that fed it, the spirit run that produced that neutral, the low-wines lot that fed the spirit run, the strip run that produced those low-wines, and the wash that started the whole thing. With dates, notes, ratings, and SG telemetry at every link. Nothing to maintain by hand once the chain is running.
For commercial distillers this matters for compliance. For home distillers it matters because "which recipe did I use for that gin from August" is a real question every batch you bottle.
