There is no perfect consensus as to the definition of “Session Beer,” but beer drinkers can perhaps agree on the following: Session Beers are generally served on draft and average around 5% ABV or lower- so that you can drink multiple servings in a “session.” At ShawneeCraft we create Session Beers with the utmost respect for flavor and tradition but with only intermittent respect for the ABV conventions. Our Session Beers range in ABV from as low as 4.2% to as high as 7.2% and above, and are on draft at the Gem & Keystone and other selected establishments.
This is the trademarked image from ShawneeCraft's website. I reproduce it here as news, and will take it down if they simply ask.
So you look at these draft offerings, and they're mostly just that: draft, as opposed to their "Heirloom Beers," which are usually bottled, but occasionally draft as well. They're mostly around 4.8%, which is too high for me. Still, I'm not going to call them out or anything on those, but... it's pretty simple that a 7.3% beer is not a session beer, and you can't fig-leaf that big swinging dick by saying "there is no perfect consensus as to the definition of 'Session Beer.'" Because even the YAAAA! EXTREME BEERS! guys at BeerAdvocate cap it out at 5%, and the DINGistas cap it out at 4%, and even Full Sail (who will, I'm guessing, likely be having something to say about that "TM" on "Session Beers") has their two at 5.1% and 5.3%. I retain hope that they'll eventually ratchet those down.
But be all "we're craft brewers so we do what we want" as much as you please, that's not going to make a 7.3% beer a session beer. It doesn't even fit in with the rest of your offerings in the line! So why not call them "Draft Beers" (and don't bother with the ™, "draft beer" ain't trademarkable and everyone knows it) and make more sense.
I'm not being a jerk. But if we don't set hard limits on this, it will soon mean nothing, and we'll have 6% session beers. If you're a brewer and don't want to put in the effort to make a great tasting beer at lower ABV, then just don't do it. And if you make a great-tasting beer at 7.3% -- which the ShawneeCraft Pumpkin Saison is, it's amazing -- why not just call it "Great-tasting Beer!" instead of trying to hop on the session beer bandwagon by calling your pig a parakeet.
