I've tried a few moderately expensive beers over the years but never anything more than, perhaps, £10. Every now and then I'm tempted by pricier options but... I'm not sure I'd be able to tell the difference :)
I'd love to know about other people's experience of splurging on special bottles. Maybe you'll tempt me to splash some cash.
The most expensive beer I have tried was Brooklyn Black Ops at £23 for 750ml. It was a delightful beer, and you obviously pay a premium for beer imported from the US, however I have had equally as good from British breweries at a fraction of the price.
I've got one of the Oh My God He's A Bozo from Evil Twin waiting for xmas... it was £24 for 700
Have you tried it yet, Adam?
