Today is the 40th birthday — The Big 4-O — of Collin McDonnell, co-founder and brewmaster for HenHouse Brewing. Collin used to brew for Drake’s, and in 2011 began moonlighting with his own brewery, HenHouse, before cutting the cord and concentrating on only his own venture, along with partners Scott Goyne and Shane Goepel. After starting in part-time space they could only use on the weekends, they moved into an Alternating Proprietorship with Petaluma Hills Brewing, but now have their own brewery, and tasting room, in southern Santa Rosa, plus took over Petaluma Hills Brewing former brewing space as their own for another taproom. Collin, and HenHouse, makes terrific beer, and I love Collin’s opinionated twitter presence. Please join me in wishing Collin a very happy birthday.
