distillation with charcoal or other materials, as to be without
distinctive character, aroma, taste, or color.
(c) Class 3; gin. ``Gin'' is a product obtained by original
distillation from mash, or by redistillation of distilled spirits, or by
mixing neutral spirits, with or over juniper berries and other
aromatics, or with or over extracts derived from infusions,
percolations, or maceration of such materials, and includes mixtures of
gin and neutral spirits. It shall derive its main characteristic flavor
from juniper berries and be bottled at not less than 80 deg. proof. Gin
