I've decided to start using 22oz bottles to reduce the total number of bottles needed for each batch (not to mention the fact that I don't remember the last time I just had one). I did a quick search but didn't find anything on how much headspace is ideal for this size bottle. Do people typically follow the same rule as 12oz (i.e. as much as is displaced by the bottling wand)? Or would you leave just a little bit more space than that? Thanks.
