I use the cornelius 19L kegs & condition with 100grams of sugar/keg.Always sit the beer in the fermenter long enough to clear well before kegging ( keeps the yeast down in the keg as conditioning feeds it obviously) Alow the beer to mature for at least a month before putting in the chiller & then blow off the first pint or so to clear yeast. Pour this on your plants, it's a great food!.
