Green Flash has a new beer called Rayon Vert, it is french for green flash from my understanding. We it states that the beer is bottle conditioned. I bought a 4 pack the other day and it does have a lot of yeast sediment at the bottom. Anyways, I am cultivating the yeast now for a Saison that I am going to brew (added in 2ndary). The yeast has taken off in just 3 days. I plan to taste it this weekend to make sure it is the ale and brett only and not Champagne yeast.
Anyways, Here are some pictures on my Homebrew Blog...
