Hi, like a few others I guess I separate out the wort from the grain by running through a rectangle of 21 mm copper tube that has slots cut in it. I tie a sparging bag round this rectangle before I pitch the grain. I mash for 1 hour at 68 deg c, then drain, sparge etc. The copper tube is dull and brownish at start, but bright pink at the end, and the bag is coloured light brown. Brews with only pale malt grain and hops are artificially dark in colour, presumably dissolved copper. I am making a new device using stainless steel tubing, but any thoughts, anybody ?
