Sour beers

Have you ever heard of sour ales? This style, also known as spontaneous fermentation or lambic beers, is a true Belgian specialty with a highly particular production process. In fact, to brew a lambic beer, there is a special recipe. First of all, the wort must be made also of wheat and not only of barley malt. Aged, dry hop, which is less bitter, is added during cooking. However the main specificity of spontaneous fermentation beers is the following step. After cooking, the wort is left exposed to open air for several hours in shallow, flat metal pans placed under wooden roofs. This way, wild yeasts can inoculate the precious liquid, lending sour ales their distinctive taste. This process is generally only possible between October and May, as in the summer months it is too hot for it to work properly. The mixture is then poured into barrels for fermentation. This process may take a long time, even years. And this is how you make a lambic beer!

Lambic beers are rarely drunk pure, they are mostly the base for three main types of beer. The first one, probably the least popular, is the faro. The brewer adds candy sugar to the lambic, to make a sour yet rather sweet and round beer. Given its short shelf life, faro is rarely bottled. A classic of this style is the Lindemans Faro Lambic.

The second type is the gueuze, which is produced with a mix of young (6 to 12 months of fermentation) and old (up to 3 years) lambic beers. This triggers a second fermentation in the bottle. This kind is known for being the sourest of all, as well as the most traditional of spontaneous fermentation beers. The Oude Gueuze from Timmermans, several times award-winner, and the Gueuze Lambic Bio of the Cantillon brewery are two illustrious representatives of this category. Numerous other gueuzes are worth the detour as well!

Finally, fruity lambics. As suggested by the name, this type of beer is produced by mixing lambic and fruit, to obtain relatively sweet beets. The most used is cherry, to produce the kriek. A good representative is the Liefmans Kriek Brut. The same can be done with lots of other types of fruit, and the Lindemans brewery has made this its specialty (Pêcheresse, Framboise, Cassis, etc.).

Be as it may, sour ales never cease to amaze!
