A miniature is a small bottle of a spirit, liqueur or other alcoholic beverage. Their contents, typically 50ml, are intended to comprise an individual serving. Miniatures may be used as gifts, samples, or for promotional purposes. In Northeast of the United States they are known as “Nips”. They are sometimes available in hotel mini-bars, on trains and planes, and in other circumstances where serving from a full size bottle is impractical or uneconomical. They are sometimes sold in sets, allowing the comparative tasting of different types of beverage. They are also sold in gift sets with a corresponding drinking glass. Miniatures are collected by some people, with various clubs and societies serving the hobby.
