Basically, everything SoG said below. Impossible to find: no signs, not visible from the road (tucked back in the woods), and once you finally find the address and ask yourself "is this the right place?" as you wind up the gravel driveway, it looks all the world like a residence (that’s because one of the two cabins on-site *is* a residence) until you see the delivery truck. But it’s worth the trouble. Note on buying Lake Louie beer when you’re in town since the brewery itself can’t sell: stop by the Firm Worm convenience store on the highway strip in town; they usually carry everything available according to season.
Imagine this: live in a cabin in the woods, walk across the driveway to the other cabin and brew suds as a career. Like the catfish-dude on their label says, "This is Livin’." It sure is, and I’m jealous.
