I'm guessing Tsing Tao is different here to that in China as over there it was usually 3.2% and sometimes 2%. The premium was 4%, but that was rarely available and had to come direct from the brewery in Quingdao. I wasnt a fan at all of any of the Chinese beers as you'd obviously never feel any effect. 40p for a big bottle though, but pretty pointless.
I agree with most of the above in that larger is pretty much all the same. I would give a hat tip to Chang in Thailand though as it was strong as hell and didn't taste terrible in the way that the extra strength lagers usually do. Had some fun nights drinking that.
Red Stripe is nice on a hot day.....and the cans do look cool
