Akrotiri 71,
Thanks for that, and the link. How interesting, I'm now convinced that the holder is a good idea, the beer inside not so good. I do hate the thought of wasting good ale. Perhaps more contributors would read that article and comment. I'm actually considering at our next attempt a beer can in one, and nothing in the other, might be a more relevant comparison. One thing I do know is that I must get good quality lumpwood charcoal, the briquettes are the pits for me.
