Diametric Brewing Company is an independent, brewer-owned craft brewery and taproom at 949 NE Columbus St in Lee’s Summit, Missouri. Founded by friends out of a local homebrew club, it pairs an eclectic, experiment-friendly tap list with Burn Theory Fire Kitchen, an in-house hickory-smoked barbecue and fire-cooked pub kitchen.

Description

Diametric Brewing Company is a craft brewery and taproom in Lee’s Summit, Missouri. It styles itself around “fun loving friends making fun beer,” and the founders’ tastes drive a deliberately broad, experiment-friendly portfolio — Sean favors yeast-forward Belgian-style wits and saisons, Devin pushes the envelope on ingredients and flavor, Mac runs from sours to stouts, and Mike leans toward pilsners, IPAs, and sour beers.1 The result is a rotating tap list spanning hazy IPAs, light ales, rich porters, and seasonal/experimental brews.2

The taproom shares its address with Burn Theory Fire Kitchen, a scratch kitchen specializing in hickory-smoked barbecue and elevated, fire-cooked pub fare run by head chef and pitmaster Taylor Jones, who connected with the brewery’s owners through a local homebrew club.3 In early 2026 the brewery added a zero-proof cocktail program for Dry January, drawing local TV coverage.4

Ownership and history

Diametric is independently and locally owned by a group of partners — Sean Householder (listed as the brewery’s primary contact and an owner/officer/brewer), along with Devin, Mac, and Mike, all of whom are owners and officers.15 The brewery’s roots are in the Lee’s Summit-area homebrew scene: the owners and pitmaster Taylor Jones came together through the ZZ Hops homebrewers’ club, and the food side (Burn Theory) grew out of that relationship when the brewery sought an in-house kitchen partner.3

The business opened in July 2018 under the name New Axiom Brewing Company, then rebranded to Diametric Brewing Company on its one-year anniversary (mid-2019).2 Vestiges of the original identity persist in third-party databases that still reference the newaxiombrewco.com web address.6 The seed record’s founding year of 2016 was not corroborated by any source and appears to be incorrect; the verified opening is July 2018 (New Axiom) / 2019 (Diametric). on the exact rename date and on whether any pre-2018 planning/incorporation predates the taproom opening.
