What is tbls of nutrient? also what temp does this have to sit at? I was looking for an easy wine to get started in wine making, this looks like the one. i like that you give options to make it our own. As a beer brewer and never having done a wine before, I'm going to try this recipe. Does this bubble through an air lock like a beer would? I usually use a blow off tube for beer since they can really bubble off and explode your top even. Thanks!
