Re: *BEER* shouldn't be 'cold cold'
Horses for courses[1]. A good pint at cellar temperature, nice for more-or-less any day. It's still nice on those occasional really hot summer days, but then a properly chilled Weizenbier becomes the greater pleasure.
And that's in Blighty. When I lived in Italy, I completely lost the taste for English ale. Not just in those hot summers, but all year, including the occasional brief return visit to Blighty. I only re-acquired it when I'd been back long enough for my body re-acclimatise.
