Beer mat

A coaster, drink coaster, beverage coaster, or beermat is an item used to rest beverages upon. Coasters protect the surface of a table or any other surface where the user might place a beverage.

Public houses usually will have beermats spread out across their tables. They are used not just to protect the surface of the table, but, as they are usually made of paper, they can also be used to absorb condensation dripping along the glass or serve as an ad-hoc notepad. Beermats are often branded with trademarks or alcohol advertising. Beermats are not to be confused with bar mats, rectangular pieces of rubber or absorbent material used to protect the countertop and soak up spilled drinks in a bar or pub.

Back in 1880, the first beermats made of cardboard were introduced by the German printing company, Friedrich Horn. In 1892, of Dresden manufactured the first beermat made of wood pulp.Watney brewery introduced them to the United Kingdom in 1920 to advertise their pale ale. The packaging company Quarmby Promotions, established in 1872, began manufacturing beermats in Milnsbridge in 1931. After Quarmby Promotions was taken over by the Katz Group, it moved production to Brighouse and in 2006 to Morley, West Yorkshire, before closing its production in 2009.

Saucers are also long used in western culture for much the same purpose. When drinking tea, it is customary to use a cup and saucer set. By the mid-twentieth century, beverage coasters made in many materials and styles were being manufactured for domestic use. Today, they are common as an everyday houseware piece and as well as used in restaurants.

Coasters are often made from high grammage paperboard, but may also be made from several layers of tissue paper. Important parameters for beer mats are water absorbency, wet rub and printability.
