Make Beer At Home

Hop garden Where hops are grown. Also known as hop yard.

Hop oil The component of hops providing aroma (essential oils).

Hop pocket A large sack packed with hops.

Hop preparations Extracts of hops, usually made with liquid carbon dioxide; can be used at various stages in the brewing process to introduce bitterness or aroma to wort or beer more efficiently.

Hop resin The precursors of bitterness in beer (_-acids).

Hopped wort Wort after the boiling stage.

Hordein Insoluble storage protein in barley that is broken down during malting and mashing.

Hormone Small molecule that switches on or off events in a living organism; e.g., gibberellins are hormones that switch on enzyme synthesis in barley.

Hot break Insoluble material that drops out of wort on boiling.

Hot water extract A measure of how much material can be solubilized from malt or an adjunct, obtained by carrying out a small-scale mash of the material and measuring the specific gravity of the resultant wort.

Husk The protective layer around the barley corn. Also known as hull.

Hydrogel Material derived from acid treatment of silica that is used for the removal of potential haze-forming materials from beer ("chillproofing").

Hydrolyzed corn syrup Material produced by the acid or enzymic hydrolysis of corn starch; can have different degrees of fermentability. It is added to the wort kettle, thereby providing an opportunity to extend brewhouse capacity by avoiding the need for mash extraction and separation stages.

Hydrometer Device operating on a principle of buoyancy for measuring the specific gravity of a solution: the higher it floats, the more material is dissolved in the solution.
