"But no more then grains, process or hops. I would say the largest influence on flavor is cleanliness. JMHO"

Having won 12 ribbons at the WA State Fair, I can tell you that's not necessarily true.

Cleanliness is paramount in all fermentation...but temperature is critical when it comes to any beer. It's important to ferment at the lowest temp the yeast will tolerate and still be active enough to crowd out nefarious bacteria and "other" yeasts. When fermented too warm you end up with those crappy Belgian Ales:)

Garbage, each and every one lol

Seriously, Cleanliness and Temperature are key.

I LOVE Belgian Witbeers, and their American Wheat counterparts.

I think brewers use Candida to brew Steel; Reserve.

Interesting. My experience has been that temperature is over rated.
