Casos de Uso
- •Calculating bitterness for a new recipe.
- •Balancing hops across multiple hop additions.
- •Comparing IBU of different hop varieties.

Fórmula
IBU = (W × U × A/100 × 1000) / V. Where U = bigness factor × boil time factor (Tinseth).
Preguntas Frecuentes
What is IBU?
IBU (International Bitterness Units) measures the bitterness of beer from hop alpha acids. Most beers range from 5 to 100 IBU.
What is the Tinseth formula?
The Tinseth formula calculates hop utilization based on boil time and wort gravity, giving a more accurate IBU estimate than simpler methods.
What IBU is considered bitter?
Below 20 IBU is low/mild, 20–40 is medium, 40–60 is high, and above 60 is very bitter. IPAs typically range from 40–70 IBU.
