I am getting ready to bottle a sour stout, Tart of Darkness one from More Beer. It has been in secondary for 10 months or so. Do I need to add a little yeast when I bottle?
After 10 months I would use a bottling yeast. However, it will probably carbonate fine on it's own; the Sacc yeast will be dead by now, but there will be some Brett working in there that will do it. It might be slow.
