Review on Hydrometer and Test Jar Kit: Perfect for Wine, Beer, and Kombucha Testing - Includes 250ml Plastic Cylinder, Cleaning Brush, and ABV Storage Bag by Antonio Bacon

I have been teaching biochemistry for almost 30 years. When my school was sending students home during the COVID-19 outbreak, a colleague and I devised an at-home experiment that fermented beverage bags. We ordered one of these hydrometers for delivery to each student; everything they needed to determine the alcohol content of their fermentation was provided – a hydrometer and plastic graduated cylinder to carry out the test, as well as a handy chart with instructions on how to calculate the alcohol content. I had a little trouble reading the scale because the graduated cylinder is opaque, but my eyesight isn't very good. The price of this product was also good. Good product!
