Just brewed up an extract batch of this and used S-33 and there are no more bubbles at all. I did have a nice krausen for about a day and some fermentation, but now nothing. I have swirled the carboy once per day to stir things up a bit.
I did have the yeast in the fridge for about a month, but did not think that would matter. Do I need to get another pack and pitch more?
