Yea. The recommended 1/2 tsp for every pint. I’ve already dispensed about 4/5 pints in total. Will this make a difference? It is dispensing rather quickly when I do it.
Ideally try stop the leak and leave it for 2 weeks for secondary fermentation, I know it's difficult not to try a drop . You won't need to add anymore sugar.
When it comes to drinking time try a pint and add Co2 if it's needed.
