The happy dudes behind Buffalo Bayou Brewing Co. wouldn't dream of releasing their Gingerbread Stout without throwing a rowdy fete. To usher in a limited supply of the Christmas spirit in a glass, the brewery is opening its garage door and welcoming craft beer lovers to taste the beer, alongside music by Westbound and Second Lovers, sustenance by Good Dog Food Truck, special appearances by the Gingerbread Man and Santa — and even a special batch or two of experimental suds.
