Belgian Saisons are an interesting category of brews. Though regarded as a distinct family of beers in the late 1800's and early 1900's, and especially associated with the summer season, there really is no clear definition with respect to the raw materials or processes used in production. They have typically been made by a handful of small and artisanal breweries, often whose origins were as farms.
The field workers shown in the design on this month's glass selection were likely the primary market for the beers, and the reason that they were developed in the first place. The brews had to be sturdy enough to last for the summer months, when brewing was impossible, but not too strong to be a harvest quencher. Key to the flavor was high carbonation, healthy hopping, a thirst cutting acidity and a crisply quenching finish. And certainly no parched farm worker of Hainaut, on the western side of Wallonia, would be seen drinking from a delicate tulip glass--hence the simple, sturdy tumbler, comfortable in the hand when held at the bevels. A functional glass for the agricultural lifestyle.
