Saison (French, "season") is the name originally given to refreshing, low-alcohol pale ales brewed seasonally in farmhouses in Wallonia, the French-speaking region of Belgium, to refresh farm workers during harvest season.
Modern-day saisons are also brewed in other countries, particularly USA, and are generally bottle conditioned, with an average range of 5 to 8% abv, though saisons at the more traditional 3.5% strength can still be found.
Although saison has been described as an endangered style, there has been a rise in interest in this style in recent years, with Saison Dupont being named "the Best Beer in the World" by the magazine Men's Journal in July 2005. Historically, saisons did not share identifiable characteristics to pin them down as a style, but rather were a group of refreshing summer ales. Each farm brewer would make his own distinctive version.
