Great yeast that is slowly becoming a part of my house culture
I did a Saison with this and it came out pretty great pitched at the same time of the Saison yeast. a 2 step starter was used (800ml to 1600ml) and I had some nice funk after only 2 months for a nice clean but funky saison. Definitely has that fantastic over-ripe pineapple aroma I wanted (like when you smell an almost rotting pineapple).

I have plans for this yeast for a house mixed culture that I'm putting together and will slowly add other strains in with this one.

outstanding
Used as sole yeast for an Apricot Blond, with NZ Wai'iti hops finishing. Pineapple-y notes from BrettC and citrus from hops blended amazingly with apricots.

As primary, fermentation was surprisingly normal, bubbling in 10-12 hrs, thick krausen by 36hrs. Krausen looked like blown-in insulation, but overall it behaved just like a Sacc brewers yeast, with the caveat that another reviewer mentioned - the yeast sediment is extremely fluffy, either accept that you'll drink much of it, or don't bottle-condition. (and if you bottle-condition, plan for it to attenuate quite a bit over the next month - once krausen falls it will continue to chew through less-fermentable sugars for weeks - brett is extremely capable, can even eat sugars in oak)

I want to try it in several other styles as primary yeast, in secondary for an old ale, and I already have ingreds for another apricot brett blond.

Versatile
This strain is great for several applications. I like to spike golden ales or saisons at bottling/kegging with this strain; it gives fantastic pineapple and musty flavors/aromas.

Its a great strain to use for lambic/flanders brewing in conjunction with another blend or bottle dregs.

Its also a very nice primary yeast. It produces a dry beer with very subtle, juicy-fruit esters. It does take some time to clear, which is best done in the keg. In the bottle, the powdery yeast can be easily roused and end up in the glass.
