I posted this question on the Brewing Network forum and got some interesting ideas so I thought I'd pop it up here too.
It's my 40th birthday next August and I'm planning to brew a decent beer or two to enjoy at the celebrations. I expect I'll knock up a few 1.040 session bitters but I'm wondering about something big and bold. I brewed a barley wine this year and that'll still be going strong so I think I should try something different.
Any ideas?
