Honestly, I've only been brewing since March of this year, so about 8 months, and I'm still trying to find what I like to brew and how I like to brew (and ferment) it. The idea I'm going for here is that I'm trying new yeasts and beers I've never brewed (and some I've never tasted). Generally, I'm using whichever yeast is being suggested for the particular style I'm looking to brew. I then try to find another beer that I can brew just before or just after using the very same yeast.
My local home brew shop just switched to Wyeast and I checked the fridge today and there is Wyeast 3068 available, so that one is on deck. Here's the info I dug up on it:
Wyeast Labs Weihenstephan Weizen - 3068
Yeast Type Wheat
Yeast Form Liquid
Floccuation Low
Attenuation 75.0 %
Optimum Fermentation Temperature 64.0 °F - 75.0 °F
Description Classic German wheat beer yeast, used by more German Brewers than any other strain in the production of Wheat beer. Properties dominated by banana ester production, phenols and clove like characteristics. Extremely attenuative yeast, which produces a tart thirst quenching finish. Extremely low floccing yeast remains in suspension readily with proteinacous wheat malt. Sometimes used in conjunction with lager yeast and kerausened to finish the beer and improve the overall dryness. High CO2 levels, typically at 2.7 - 3.2 volumes is desirable for best presentation. True top cropping yeast requires full headspace of 33%. Ester formation is significantly affected by aeration and pitching rates. Crystal weisse production typically requires DE filtration, may prove too difficult for Pad filtration only.
