Oh that looks good. I am well familiar with that feeling my friend! I don't know how hard it is to get them. There are a few craft beer shops that have sprung up around Glasgow and I usually prowl about them at the weekend looking for new things! Most of them are imported so should be available all over the place!
It did feel like something was pissing in my mouth, leopard was the first that came to mind! hehe :O)
