Flathead Lake Brewing Company

What Flathead Lake Brewing Company does

Flathead Lake Brewing Company (FLBC) is a Montana-based craft brewery founded in 2004 by Greg Johnston in Woods Bay, MT, and now operating from a Bigfork facility opened in 2015. The company operates a 30-barrel Sprinkman brewhouse with eight 60-barrel fermenters, three 20-barrel fermenters, a canning line, and a dedicated temperature-controlled Sour Beer Room, with potential annual capacity of 5,500 barrels (expandable to 9,000). Its product portfolio spans 15+ SKUs including IPAs (Beardance, Centennial, Zero Day), stouts and porters (369' Stout, Painted Rock Porter), lagers and pilsners (Flathead Premium Lager, Italian Pilsner, Montana Light Kolsch), pale ales (Two Rivers Pale), fruit ales (Bluff Charge Huckleberry), the barrel-aged Jewel Sour Series, and Hop Water (a non-alcoholic sparkling hop water launched 2025). Core technology centers on craft fermentation, a wild-yeast barrel aging program using Brettanomyces, Lactobacillus, and Pediococcus cultures aged 6 months to 2 years in oak casks.

The business operates a dual-channel model: direct-to-consumer revenue from the FLBC Pubhouse (full food menu, draft and canned beer, on-site events) and dock sales at the brewery, alongside wholesale distribution of canned and kegged beer across Montana, Eastern Washington, and Northern Idaho via a single sales manager. The pubhouse functions as a community hub, hosting monthly Science on Tap lectures (co-presented with Flathead Lakers and Flathead Lake Biological Station), comedy nights, weekly trivia, and live music. The Bigfork building is notable for sustainability infrastructure: a geothermal heat-pump system drawing clean effluent from Bigfork Water and Sewer District, and a rooftop solar thermal array for kitchen water heating.

FLBC is a family-owned private company (Greg Johnston, Sandy Johnston, Nic Lee as co-owners) with no external institutional investors or parent company. Financially, the company is opaque (no revenue disclosed); production capacity and a 3-state regional footprint suggest a sub-$10M revenue base. The most distinctive competitive position is the dedicated sour beer program — the only of its kind in Bigfork — combined with a multi-decade award track record (World Beer Cup 2006, inaugural Montana Sustainabrew Award 2018, plus 19+ regional medals). Customer concentration risk is structurally low given the consumer-facing B2C mix across retail, on-site, and wholesale channels.
