If you already didn't know, there's going to be a total solar eclipse on Monday, August 21. Whether you care or not, this eclipse is sort of a big deal- 99 years in the making.

And what's one of the most Colorado ways to celebrate this historic event? Spend the morning at a brewery.

Here's what four breweries in Colorado are doing for the solar eclipse.

This space-themed brewery will release a beer called "Penumbra" in honor of the solar eclipse on Friday, August 18 at noon. It's a (hold on, this is a mouthful) Law's Secale rye whiskey barrel-aged imperial brown ale. Sadly, the brewery will not be open early enough to watch the eclipse from. But the early release date of Penumbra is for people to grab bottles before traveling to go see the eclipse. Launch Pad's hours on Monday will be the usual 3 p.m. to 9 p.m.
