🍺 Homebrewing Calculators

Practical tools for calculating alcohol content, bitterness, carbonation, brewing water, and recipe parameters.

Calculate the approximate alcohol by volume using original gravity and final gravity.

Original Gravity (OG) Final Gravity (FG)

—

Estimate bitterness using the Tinseth method for a single hop addition.

Wort Volume (L) Wort OG Hop Amount (g) Alpha Acids (%) Boil Time (min)

—

Note: Actual bitterness depends on several factors, so this is an estimate.

Estimate the amount of priming sugar needed for bottling based on beer volume, temperature, and target CO₂.

Beer Volume (L) Beer Temperature (°C) Target CO₂ (vol) Šećer

—

Important: Bottle only when fermentation is complete and FG is stable. Over-carbonation can be dangerous.

Estimate the amount and temperature of strike water needed to reach your target mash temperature.

Grain Amount (kg) Water-to-Grain Ratio (L/kg) Target Mash Temperature (°C) Grain Temperature (°C)

—

The formula uses an approximate grain heat capacity of 0.41. Heat loss, vessel type, and brewing setup may require adjustment.

Use the average grain potential expressed in PPG (points per pound per gallon).

Wort Volume (L) Wort Gravity (SG) Total Grain (kg) Average Potential (PPG)

—

For a more precise result, enter the PPG for each grain and calculate them individually; this is a quick estimate.

Calculate the expected FG from OG and the yeast apparent attenuation percentage.

OG Attenuation (%)

—

Enter the original and new batch volumes. The calculator gives you a scaling factor to multiply each ingredient quantity by.

Original Volume (L) New Volume (L)

—

Example: If a recipe calls for 4 kg of grain and the scaling factor is 1.50, the new amount is 6 kg.
