Q

How do hops affect the final gravity of a beer? I recently brewed a new England IPA with 12 ounces of hops for 5 gallons (19 l). The final gravity was 1.018 and i expected 1.014 with the Gigayeast Vermont IPA yeast. So to me it tastes stronger than the 5.5% ABV that i calculated, and i don’t understand why the hop content Doesn’t make the hydrometer
float higher.

Hops do not have a significant impact on wort or beer density because the concentration of hop soluble compounds is simply too low to make much of an impact on density. In
