re: Homebrewing: Fermentation possibly stuck

Just curious, what was your OG?

If I remember right, the pumpkin porter I brewed last year slowed and then continued at about a bubble every 10-15 seconds for about a week. I kept checking it to see if I should take a reading and I would see a bubble. I used Safale-05 though. I don't think it was as short as 1 day, but I remember the "vigorous" action didn't last very long, but then it slowed and kept on going for a while.

I'm no chemist or biologist, but I wonder if the yeast just has a harder time getting the sugar from the pumpkin that it does eating the malt sugar.

It would be interesting to see what the predicted OG would be for the recipe without the pumpkin added, and how it compares to the actual OG with the pumpkin.
