Just picked up one of these as a christmas pressie for the neighbour and one for myself just for the novelty value. The bloke at the shop reckons they've been selling like hotcakes at stores all over. Only bit of feedback that he had, for whatever its worth, was that someone reckoned it was like a honey beer. Don't know how on the mark the comment is but it probably indicates, as Kev said, that its better than aussie megaswill.
The other bloke in the bottle shop in true fashion advised me to chill the stein, put the beer in the freezer till almost frozen then pour and drink. Ha ha. Yeah right, you can drink anything when its so cold that it has no flavour - the trade secret of megawill producers and pubs Australia wide.
Anyway, don't think I'll be doing that, though I may chill the stein in the fridge to help keep it cool during the time it will take to drink the sucker. 20 minutes eh Kev?
