Thanks for the link, Denny.
It's interesting in that there seem to be some subjective flavor differences between OO and O2 from the triangle tasting which are probably unlikely to appear in the analysis from White Labs.
It would be cool to see more data points than just the one triangle testing, but I'm not stepping up to the plate on that. Me = lazy.
I've used OO once or twice in starters. Can't say that I've noticed it contributing anything either positively or negatively.
