Some people, still a relatively small but by all accounts growing percentage of the population, have sensitivities to gluten. I know and have known several such people and have seen the effects on their health first hand. Of this there is no doubt.
Others have jumped on the “Wheat Belly” bandwagon and decided for reasons of their own to eliminate gluten-containing grains from their diets. Which is, of course, purely their personal choice and fine and dandy by me.
Although it is the first group that has much more to lose by ingesting gluten, it is the latter group that, to my experience, is more active in questioning issues of gluten in alcohol, and in some instances, perpetuating mythologies. So for the record, here are a few points about glutinous booze:
1) Beer contains gluten. Major brewery beers contain gluten and craft beers contain gluten. Wheat beers and rye beers and stouts and light beers and pretty much any other kind of beer you can name contains gluten. Period.
2) Gluten-free beers are, of course, the exceptions to the above rule. Unfortunately, very few of them taste much like actual beer. (Although not all, as per point 6 below.)
3) Distilled spirits, of whatever sort, do not contain gluten. This is because the process of distillation specifically involves the separation of alcohol from everything else, including the gluten in glutenous grains. But don’t believe me, believe celiac.com!
4) Flavoured spirits may or may not be gluten-free, since said flavours are generally added post-distillation and few offer any details as to what is used in their flavouring. The same applies to liqueurs.
5) Wines are gluten-free, including Champagnes. Since they are made purely from grapes, I don’t understand why some people insist on challenging this fact.
6) Although I have not personally tasted all the gluten-free beers on the market today — as a class, it’s growing almost exponentially — the best I have sampled are those of Quebec’s Les Brasseurs Sans Gluten, marketed under the Glutenberg label. In particular, their seasonal Belge de Saison, a 7% alcohol ale brewed with Meyer lemon, is far and away the finest, more a “good beer than happens to not contain gluten” than any other I’ve yet tried. It deserves to be a widely-sold, year-round brand.
