Why Brewlog

The notepad next to the fermenter.

Every brewer starts the same way. A notepad, a pen, and a hydrometer. Brix readings scribbled between punch-downs. A date circled when something seemed important. It works — until you want to compare this batch to the last one, or remember what pH you had at press.

Brewing doesn't happen at a desk. It happens in the garage, in the shed, standing over a fermenter with sticky hands. You need something you can pull out of your pocket, punch in a reading in five seconds, and get back to what you're doing.

Brewlog replaces the notepad. Capture a note or a reading in seconds — on your phone, right where you brew. No setup, no fuss. Just open it, log it, done.

Beer Brewing

Track gravity, temperature, and every stage from mash to glass.

Mash

Done

Convert starches to fermentable sugars at target temperature.

Mash temp determines body. Lower (63°C) = dry and fermentable. Higher (68°C) = fuller body. pH affects enzyme efficiency.

Winemaking

Monitor Brix, pH, and TA through crush, fermentation, and aging.

Crush

Done

Destem, crush, and take initial readings.

Your baseline numbers. Brix tells you potential alcohol, pH and TA guide acid adjustments before fermentation even starts.

Distilling

Log your cuts, track ABV across the run, and dial in your process.

Wash Fermentation

Done

Ferment your base wash to maximum attenuation.

Higher wash ABV means more spirit per run. Track OG to FG — you want it fully attenuated with a clean ferment.
