Two Water Brewing Co.

Located in a plaza on Corunna's main strip, about 20 minutes south of the Sarnia/Port Huron border crossing (402 highway). They have a patio in the parking lot, with a modest interior that can seat a decent number of people. They hold events fairly frequently (e.g. trivia night, live music, etc.), so if you're visiting during peak hours, you might want to call ahead and see if there's room.

They have some snack-type food available in-house, and there are several restaurants in the vicinity that will bring food to the taproom (e.g. pizza, burgers). There's also a really nice ice cream parlour next door. Good service, good vibe. They typically have anywhere from 6-10 different beers available, with cans-to-go available for purchase if you're in a rush. Their beers are generally fine, definitely not amazing but still serviceable. You can also try some local wine or seltzers, if there are folks in your group who don't drink beer.

All in all, it's a cozy little brewpub, slightly off the beaten path. If you're touring the brewpubs of Sarnia-Lambton, make a point of passing through Corunna to visit Two Water.
