Firstly someone needs to define appreciation.
Is it, the appreciation of the flavours and mouth feel of the beer?
The over-all look and appearance of the beer?
The complex mix of malt and hops?
The detail of the water profile?
The precise adherence to temperature control?
The ability of the strain of yeast to consume maltose and produce alcohol?
Or the level of craftsmanship and effort put in by the brewer that's being appreciated?
I could go on but feel I am being rather pedantic
Lylo has it right...."Beer good".
