About BrewGod

What is BrewGod?

BrewGod is an independent, advertising-supported website built around six free home-brewing calculators — the ABV Calculator, IBU Calculator, Priming Sugar Calculator, Strike Water Calculator, SRM Color Calculator, and Brix to Gravity Calculator — along with brewing guides and a Beer & Brewing Museum. It isn’t a brewery, a beer brand, or a homebrew supply shop, and it isn’t affiliated with any brewery, brand, or certification body it might mention.

Who is it for?

Anyone brewing beer at home who wants a number instead of a guess — a first-time kit brewer checking their first alcohol reading, or an all-grain brewer working out a strike temperature or a grain bill’s colour before brew day.

What tools are on the site?

The ABV Calculator turns your original and final gravity into alcohol by volume and apparent attenuation. The IBU Calculatorestimates hop bitterness from each addition’s weight, alpha acid, and boil time. The Priming Sugar Calculator works out the grams of corn or table sugar needed for a target carbonation level. The Strike Water Calculator finds the water temperature and volume to hit a mash target. The SRM Color Calculatorpredicts a beer’s colour from its grain bill, and the Brix to Gravity Calculator converts refractometer readings to specific gravity.

How do the calculators actually work?

They use published homebrewing formulas, not house guesses. ABV comes from the standard OG/FG formula, ABV = (OG − FG) × 131.25, alongside the apparent-attenuation calculation. IBU uses the Tinseth method. Beer colour uses the Morey equation, SRM = 1.4922 × MCU^0.6859. Strike water uses the standard single-infusion equation. Priming sugar is worked out from residual CO₂ dissolved in the beer at its warmest point during fermentation, set against your target carbonation.

Where do the numbers and methods come from?

Tinseth, Morey, the standard infusion equation, and residual-CO₂ carbonation math are the same methods used across established homebrew references and brewing software — nothing here is invented in-house. The learn section and blog cover the reasoning behind them in more detail.

What’s in the Beer & Brewing Museum?

The Beer & Brewing Museum is a set of reference galleries on beer styles, brewing ingredients, brewing equipment, and beer culture and glassware. Its entries, images, and facts are drawn from Wikipedia and Wikimedia Commons, not written in-house.

Are the tools free?

Yes. Every calculator on this site is free, with no account or payment required. The site is supported by on-page advertising.

Do you see what I type into a calculator?

The calculators run in your browser. The gravity, weight, and temperature figures you enter are used only to compute the result shown on the page.

Is this professional brewing advice?

No. Everything on BrewGod is general informational and educational content, not professional or safety advice, and results are estimates based on the figures entered. Follow established brewing and sanitation practices, check your local laws on home brewing and alcohol, and brew responsibly.
