Point as a commercial brewer is that I only have one yeast strain.
So more beer styles I can make with my lager yeast...
Sure, but that's different. And maybe one of the reasons it's better to be a homebrewer!
I am not so sure about lager yeast vs ale yeast argument.
I am more in opinion that the same yeast under different temperature create different flavors.
I can make quite nice "ale" with "lager" yeast at 70F.
Agreed. And what I'm saying is that I don't see the point for using a lager yeast (unless like you it's all you've got) when you can get lagerlike qualities from an ale yeast.
Now we are talking.
My usual lager fermentation time is 10 days.
I made Alt with my yeast and fermented at 60F in 6 days.
If I ferment at ale temp I will be done in 4 days.
When we talk about taste.
Warmer you ferment more fruity esters it gets.
Still pretty clean thou.
I can make almost any beer with this yeast.
