1 - Testudo, a Biere de Mars made with Cleetus Friedman of City Provisions. Rare Tea Cellar green tea, lemongrass, brettanomyces yeast. Released at City Provisions on April 12th.
2 - nothing but a twitter post so far, but Two Brothers has collaborated or will be collaborating with Castelain.
Additionally, while I was in absento Two Brothers announced some kind of celebration is going on involving some old favorites, celebrating their 15th year. Something like that. Anyway, Red Eye Coffee Porter is out and possibly even around town (you might still be able to get growlers at the brewery). This is a summer project, so expect a whole lot of delicious, harder to find Two Brothers beers starting now.
Outlaw IPA coming in cans around the first of May. More posts on that as it gets closer.
