Proof Meister: Measure Spirits

DISTILL SMARTER. MEASURE ABV. STAY IN CONTROL.
Proof Meister makes it easy to measure, monitor, and manage your distilling process. Whether you're making gin, whisky, vodka, grappa, or liqueurs, measure alcohol content, track distillation cuts, and organize your production runs — all in one app.

Pair the app with EasyDens, SmartRef, or pH2Go to record precise measurements with ease. Measure density, refractive index, and pH with your Tony measuring devices. Combine EasyDens and SmartRef to determine ABV in liqueurs.

No measuring device? You can also enter readings manually.

TRACK YOUR PROCESS FROM MASH TO BOTTLING
Stay in control of your spirits production, from fermentation to the finished product.

- Monitor pH during mashing and fermentation
- Measure ABV and proof throughout distillation
- Document foreshots, heads, hearts, and tails during distillation
- Log measurements at each stage to support decisions on distillation cuts
- Track measurements during blending and bottling
