The intewebs is really aghast over this news, huh?
Remember when Constellation bought Ballast Point and Lagunitas sold 50% of their ownership (despite the owner never claiming he would never sell out?). Well guess what - Sculpin and Victory at Sea are still excellent beers.
Meanwhile Lagunitas is still churning out hits like Born Again, Waldo, and High West-ified Imperial Coffee Stout... beers that are nationally distributed and easy to purchase (for a very affordable price point, I might add).
I don't know, I could really care less. In the end it's a larger footprint for a brewery that makes some great sours.
