I always need help categorizing my beers. Everyone always tells me to enter it as what it tastes like. So, what does it taste like? Even with ale yeast, it could come across as a pilsner depending on the yeast strain, its fermentation and storage profiles...
Precisely...just enter it as whatever it most tastes like. That is. after all, the most important parameter and, in the end, the only one that really matters at all.
I've tasted lager beers made with ale yeast that actually tasted more authentically 'lager-like' than some which were made with actual lager yeast. As suggested by others in this thread, there are factors at play in the flavor profile of a beer other than the type of yeast (or other ingredients) used.
