A Very Sharp Single

I like beer. I like it enough to get annoyed when I have to wait too long to be served one. Occasionally I make allowances for my Guinness to settle because I know I’ll get a proper pint if the barman leaves it a while mid-pour. However, when I just need a cold refreshing pint of lager, I want it now and I want it often. Step forward Grin on Industries. These chaps seem to have invented a natty little device that pours lager quickly and, to counter too much head, through the bottom of the glass. This should keep the queues down at the local. Ok, here they use an American brew (or beer substitute, as it’s known), but I see no reason why it shouldn’t work on proper beer.
