|£25 wine under screw-cap.|
What I think it boils down to in the wine industry (putting aside questions of suitability for long-term ageing) is that if the screw-cap is good enough, it is a far more effective closure than even the best quality cork, but by the same token a bad screw-cap is simply a bad closure. Hence the parallel with beer. Just as putting your beer in a clear bottle suggests you don't really care about what state the beer is in by the time it gets to your customers; using an old-fashioned, non-coated can suggests the use of cans is probably just a way of getting things done on the cheap. As ever, the proof of the beer is in the tasting.
Still, I wonder if the toucan can make a comeback? (Pun intended)
