Hello, I've started to experiment with adding hops, extra malt and such like to kits. I'm about to start a Coopers Canadian Blond kit for Xmas, for people that prefer the lighter brew; but I'd like to split it, and use the fairly gentle base as a launchpad for some Citra hops and maybe a little lemongrass. If my experiment goes wrong, I've not wasted a kit / 40 pints of terrible beer to pawn off. So - my current plan is: > Brew the full 23 l as per packet instructions. > When I get a stable S.G, syphon off 10 l (so 20 bottles), cold crash and bottle. > With the remaining 23 l + yeasty sludge, dry hop (and maybe hop tea, for the bitterness) etc, leave it a few days and bottle. Am I likely to run into issues with oxidation if I'm taking 1/2 the liquid out of the FV? Should I add some sugar (or malt extract perhaps?) to produce some CO2 to help protect the 13 l left behind? Although any bubbling might drive off the light flavours from the dry hopping. Could it cause issues with the secondary fermentation in the bottles? Or stress the yeast? Thanks, I've already learnt a lot lurking around this forums, and plan to learn more!
