If you really care about the planet, you’ll eat, sleep, and especially drink the outdoors. That’s why one Canadian brewery is making beer out of tree branches, because NATURE.

Prairie Sun Brewery isn’t just proving its hippie bona fides — it’s also raising money for outdoorsy pursuits. The brewery created Meewasin 80 ale to help expand the Meewasin Trail in Saskatoon, Saskatchewan. Adding 10 miles to the trail will connect two public parks, but the Meewasin Valley Authority still needs a little over $1 million to finish the job. Graciously, Prairie Sun is donating all proceeds from Meewasin 80 to the project!

But what’s it taste like? Writes CBC News:

It’s quite authentic … It is brewed with branches from spruce and pine trees. The branches come from trees along the Meewasin Valley.

“It doesn’t taste like spearmint gum. It’s more of an aroma thing. It’s a very refreshing light-tasting beer,” said Prairie Sun’s Heather Williams.

According to Cameron Ewen, who brewed it for Prairie Sun, it’s a light spring brew with “earthy, herbal notes and woodsy flavors” (hopefully no aroma of dog poo).

The white ale launched on Thursday at a fundraising event, and now it’s on sale to the public until it runs out. But it looks like you can only find it in Saskatoon, which is too bad. Word on the street is it’s superb.
