Three times a week (per Lonely Planet), but especially on Saturday, the central plaza in El Bolson fills with crafters selling stuff and shoppers buying it. Weaving, wood carvings, musical instruments, foods, all sorts of stuff is out there.
Piltri, served up a few stalls down. I tried Piltri's rubia fuerte, the first rubia that tasted like a true Blonde Ale like American Brewing makes in Everett. Alcohol content definitely on the higher end, nice balance and a rich, lingering finish.
So that made seven breweries right in town. The next town south, Lago Puelo, has a couple more. One had a booth at the fair, Pilker, where the guys drew me another chopp of their rubia, more of a pilsner with that nice tang. One of them even named the hops they used: Cascade and Nugget. I'm guessing that our Northwest strains are grown down there.
Another neighbor town just a bit south, El Hoyo, has a brewer called Chaura. They were not at the fair, but they were the featured draft beer at Ristorante Tomatican across the street. I had dinner there after shopping at the fair, a grilled trout from one of the mountain streams in the area, with Chaura's Pale Ale.
