When I used Cooper's carb drops,I put the right amount in each bottle (2 for Cooper's PET,1 for 12oz) For as many as I think I can fill,then bottle away. No barrels,none of that. I bulk prime now with a bottling bucket.
Therefore means I have them to throw the brew away?
No! If it comes outta the barrel flat,just re-prime & bottle. Giving it time to build up co2 in the bottles.
