Dairy tanks: great for housing milk.

But also surprisingly good for holding beer.

Here’s how we know: someone in town spent two years brewing some beer in them. And then built a brewery around it, which you can now visit.

In Fort Point.

So loosen your growler-consuming jaw muscles for Trillium Brewing, the new Congress Street brewery and wood-lined retail shop, now open.

This hall of ale is how you’d expect a brewery rising up in the currently exploding Fort Point area to feel. Vintage wood sherry barrels: check. A handmade bar using wood pulled from nearby buildings: check. Metal going back to the early 1900s: check (this tends to be key for that brewery vibe).

If you get there this afternoon, you’ll be able to fill up a few 64-ounce growlers with their debut offering, a pale farmhouse-style ale (go ahead, sip it on the train home). There’s a saison made with locally grown rye coming soon, too.

Or if you can’t get there right away, know that you can also grab a pint of their flagship beer at the Publick House in Brookline (starting tonight) and Vee Vee in Jamaica Plain (starting next week).

This concludes “Today in Local Beer.”
