Overview

Hops are the cone-shaped female flowers of the hop vine, most famous for flavoring beer. Beyond brewing, hops have a long history as a calming nervine and sleep aid. The bitter compounds that give beer its characteristic flavor also have sedative and estrogen-like effects. Hops pillows have been used for insomnia for centuries.

Late summer to early autumn (August–September). Cones are harvested when mature but before they shatter. Harvest in the morning after dew has dried.

Quality Indicators

Whole cones: green to yellow-green, intact, with strong aromatic scent. Should feel papery and light. Powdered hops degrade quickly. Look for whole cone products or fresh extracts. European noble hop varieties are highly regarded.
