You would have heard the terms gravity, OG and FG in brewing. Simply put it is measuring the fermentable sugar content of your wort. Measuring at the beginning and at the end of fermentation will give your the final ABV% (Alcohol By Volume) of your home brew.
Use the Solid Glass Test Tube (100ml) together with our triple scale hydrometer to help give you an accurate gravity reading.
Start creating your very own home brew yeast bank by using this as a yeast harvester.
The solid glass cylindrical test tube is crafted out of a single piece of lab-grade pyrex and is marked for easy measuring for ‘Specific Gravity readings. Pour in your wort, place the hydrometer in the test tube, give the hydrometer a spin to remove air bubbles and measure the gravity.
