When I read fruit juice, I think of orange juice, grapefruit juice, grape juice, etc. Not sok as in the syrup used here in beer. Maybe it's just a language thing. I have drunk beer with spicy tomato juice and I like it from time to time, but a tomato is a vegetable, not a fruit.
I've tried the warm beer here and I don't like it very much, but the hot spiced wine is a very different story. I love it. Hot buttered rum is good too.
Who said that you can drink beer ice cold only and why?
God decreed that it be so.
