So I'm planning a sour saison using yeast and bacteria from bottles of beer I've recently been given for my 30th birthday. I've recultured yeast from a la siren saison and plan to do a primary ferment with this then rack to secondary where I will add dregs from 2 bottles of Orval, a 3 fontene oude gueuze and a monks cafe Flemish sour ale. I also have a timmermans oude gueuze but can't find out if there are live bugs in it or not, has anyone had any luck with these dregs or should I go with what I have?
