My question was mostly curiosity.
I had a chance for a pretty thorough (I was there about 2 hours) tour of Shipyard Brewing in Portland, ME recently with one of the brewers.
Shipyard is Maine's largest brewery and produces close to 100,000 barrels per year.
The house yeast is Ringwood.
The interesting thing, interesting to me anyway, I learned was that while they do a lot of contract brewing, 99.9% of everything they brew is done with the Ringwood yeast.
The downside is that when you go into one of the brew pubs or bars that they also operate and ask for a sampler of all the styles, they all taste pretty much the same.
