This glass wine and beer hydrometer is an essential tool for any home brewer or wine maker. It measures the specific gravity (density) of your wort, beer, or wine, allowing you to track fermentation progress, know precisely when fermentation is complete (safe to bottle), and calculate the alcohol content (ABV) of your finished brew.
How to use: Float the hydrometer in a sample of your liquid. Read the scale at the bottom of the meniscus. Take an Original Gravity (OG) reading before fermentation and a Final Gravity (FG) reading when you think fermentation is complete. When two readings 24 hours apart are identical, it's safe to bottle.
ABV formula: (OG – FG) × 131.25 = ABV%
Use with your Fermentation Vessel and Syphon. When fermentation is confirmed complete, bottle with Carbonation Drops and seal with a Beer Capper. Click the link in product description for full hydrometer instructions.
