I'm pretty sure this has been done, but I can't really find it.
Anyway... filtering.
I was looking at probably a 1micron filter. I know the theory, but how does the filtering affect the beer flavour at this porosity? I was really only looking at filtering lagers, but the odd ale may get the treatment too.
Anyone had experience with a filter less than 1micron? If so, how has it worked out?
Ross' filter looks like the one to go for, but I am still uncertain about the effect on the flavour.
