Index Beer head

Beer head (also head or collar), is the frothy foam on top of beer which is produced by bubbles of gas, typically carbon dioxide, rising to the surface. [1]

Adjuncts

Adjuncts are unmalted grains (such as corn, rice, rye, oats, barley, and wheat) or grain products used in brewing beer which supplement the main mash ingredient (such as malted barley).

Hydrophobe

In chemistry, hydrophobicity is the physical property of a molecule (known as a hydrophobe) that is seemingly repelled from a mass of water.

Laplace pressure

The Laplace pressure is the pressure difference between the inside and the outside of a curved surface that forms the boundary between a gas region and a liquid region.

Odor

An odor, odour or fragrance is always caused by one or more volatilized chemical compounds.

Ostwald ripening

Ostwald ripening is an observed phenomenon in solid solutions or liquid sols that describes the change of an inhomogeneous structure over time, i.e., small crystals or sol particles dissolve, and redeposit onto larger crystals or sol particles.

Peptide

Peptides (from Gr.: πεπτός, peptós "digested"; derived from πέσσειν, péssein "to digest") are short chains of amino acid monomers linked by peptide (amide) bonds.

Soft drink

A soft drink (see terminology for other names) typically contains carbonated water (although some lemonades are not carbonated), a sweetener, and a natural or artificial flavoring.

Viscosity

The viscosity of a fluid is the measure of its resistance to gradual deformation by shear stress or tensile stress.

Wheat beer

Wheat beer is a beer, usually top-fermented, which is brewed with a large proportion of wheat relative to the amount of malted barley.
