What is Lambic?

Lambic is a part of the Belgian beer family, a traditional Belgian style of sour ale. It is brewed in the Pajottenland region of Belgium, southwest of Brussels. Although this beer is now being brewed outside Belgium. Lambic beer is an all encompassing term for the style of beer produced with spontaneous fermentation and use of coolship which makes it stand out from other types of beer .

How it is made?

Lambic type of beer leaves it to nature to determine the fermentation. It is brewed from grist containing 60-70% base malt such as barely malt and 30-40 % unmalted wheat which is mashed vigorously for a long period of time with addition of aged hops (a year or more depending) and is then boiled. The name spontaneous fermentation comes from process used to ferment; wort is left in open vaults where, wild yeast and bacteria are allowed to take up residence, no artificial yeast is added, wild yeast converts to sugar slowly turning into alcohol and flavor components.

Wort is cooled overnight in a shallow flat called coolship (lambic beer is referred to coolship beer at times). It is worthy to note the Lambic beer is the only commercially produced beer that uses the coolship system.

The brewing of this beer has a limited window that is between October and May. It is brewed during the summer because there are many undesirable bacteria which could come into the wort and influence it. Due to climate change, the window for brewing is reduced.

After the fermentation process Lambic is conveyed into barrels, most preferably wine or sherry barrels and left to mature for up to 3 years or more.
