That is beautiful. It brings a tear to my eye. There is nothing in the world better than fermentation. Well, except beer.
Of course- I have nothing in primary. Nothing in secondary. No brewing until March at the earliest. I have nothing to live for, except to hang out here and look at photos of other peoples beer.
Metal: I haven't measured, but I think about 2 gallons. I haven't tasted yet, but there was no leftover pretzel smell in it before I filled, so I don't expect any issues.
