Every good experiment needs a measurement, and in distilling that measurement is proof. Whatever you're working on, whether it's whiskey, rum, brandy, vodka, gin or schnapps, a hydrometer lets you stop guessing and know for sure. It's the scientist's tool in a craft that can feel like alchemy.
One tool, every spirit
The spirits differ, but the question is the same: how strong is what's in the jar? With whiskey or rum, checking proof as the run goes helps you track your cuts and see how the spirit changes from start to finish. With brandy and schnapps, it helps you keep fruit batches consistent from one run to the next. With vodka and gin, a clean, repeatable strength matters, and the hydrometer lets you confirm the number before you bottle. Write the reading down every time, because your notes become your recipe.
What's in the set
- Proof & Tralle hydrometer
- Glass test jar
- Protective storage tube
- Easy-to-read scale markings
The hydrometer reads both alcohol by volume (ABV) and proof, and the instruments are lab-tested for accuracy. It's a simple, durable kit for beginners and experienced distillers alike. Keep it in its tube between uses, because glass and hard floors don't get along.
