Take the guesswork out of bottling day! Give it a chance, and your hydrometer will quickly become an indispensable part of your brewing toolbox. This simple instrument allows you to easily & accurately calculate the abv of every brew, and it will verify when fermentation is complete. No more guessing when your brew is finished -- no more bottle bombs!



Note: Your hydrometer includes factory instructions for using the "potential alcohol" scale to estimate your ABV. This scale overlooks several important factors for beer fermentation, and will likely over-estimate the ABV.

To get a more accurate estimate, use the instructions from this page.
