The kit should come with aging times, but doesn't, as far as I can see. Northern Brewer says to age theirs 3 months, Midwest for 9-12. gtotally guessing, I'd say to go with a 1 month primary and a 3-6 month secondary, then not be in any kind of a rush to drink the bottles, but for a beer that doesn't feature prominent hoppiness (either in ibus or in flavor/aroma), you can age longer with no ill effects. To bottle, use a small amount of either the exact same strain you fermented with originally, or of champagne yeast.
