What we call wild beer, many other people call “sour” beer. This is purely a preference, and not any hard and fast rule. But we wanted to explain why we feel like “wild” works a bit harder than “sour,” and what wild beers are to us.

In the fall of 2007 Rob Tod had an idea. Rob, the founder of Allagash, wanted to build a small, unheated shed with a vessel resembling a massive brownie pan inside of it. Then, he wanted to pump steaming, cloudy unfermented wort into that pan, let it sit out in the open overnight, and subsequently barrel age it for up to three years. In short: he wanted to brew with a coolship.

A saison, also often called a farmhouse ale, is a style of beer originating in the French-speaking Wallonia region of Belgium. In today’s brewing scene, it is widely accepted that a saison will be “exceptionally dry, highly carbonated, fruity and of moderate strength: 6-8% ABV.” Beyond that description, the saison style offers quite a bit of room for interpretation.
