What glass shape is most commonly used for Saison's? Is there a widely accepted glass shape/type for Saison's (and if so, what is it)? Is a different glass used for French Saison's vs. Belgian Saison's vs. other common Saison styles?
I don't think that there is a commonly accepted glassware for saisons in general.  Different sources point to 3 different types: the pint, the tupic, and the oversized wine (goblet?).  A prticular saison may be better suited to one of those three, depending on whether it was crafted to have more or less aromatic, or just a beer for simple drinking.
