New brewer here. On my sixth batch in the fermenter. Been bottling using a bottling bucket and priming sugar solution. Want to start kegging. I don't understand the steps to do this. I have two corny kegs and and a convertible chest freezer that can keep refrigerator temps. Do I need priming sugar to do this? Or do I go straight from fermentation to the keg, connect CO2, and cool? Also, does the ABV go down because you aren't using priming sugar? Thanks... Chip
