Hey all, I'm looking at cutting oxidation from certain styles at bottling, hopefully without going to the trouble of gas and bottling wand I'm wanting to find out if anyone's tried filling to the top without leaving a headspace? Is this possible? Does it require the same, or less priming sugar? I know air can obviously be compressed so this may take some of the co2 charge a priming carb vol calculator would normally estimate, hence carb rates tailored to that(?) Thanks!
