About Cocktail Ratio

What this tool does

Brewing tools calculate alcohol by volume (ABV), International Bitterness Units (IBU), strike water temperature, priming sugar amounts, dilution ratios, cocktail proportions, and keg volumes.

Why use this tool

Homebrewing is a science. The difference between a balanced IPA and a harsh, over-bitter beer comes down to precise IBU calculations and correct fermentation temperatures. These tools take the guesswork out of recipe formulation.

How it works

ABV uses the formula (OG - FG) x 131.25. IBU applies the Tinseth or Rager utilization formula based on boil time and gravity. Strike water temperature is calculated from grain weight, water volume, and desired mash temperature.

Pro tip

For consistent homebrew, calibrate your hydrometer at 60 degrees F (15.5 degrees C). Temperature affects density readings, and an uncorrected reading can throw off your ABV calculation by half a percent.
