I want to make sure I'm correct here. There isn't really a Dry yeast available to produce the banana/clove qualities if I want to brew a Dunkelweizen, right?
Danstar Munich and Safwheat WB-06 both claim to have these qualities. I have only used the latter and can say that it is much lass banana than 3068, but might be comparable on the clove. I used it in Hard Cider though.
WB-06 can be very banana, depending on the temp you ferment at. My second ever beer used it and it was near overwhelming. 3068 in my experience is much more balanced.
