Stuck Fermentation?

Tue Oct 03, 2006 8:50 am

I brewed A partial mash Robust Porter with an O.G. of 1.065 on the 22 of September. I used O2 with a stone for about 1 minute and pitched two vials of White Labs WLP001 into the fermenter. It is at 75 degrees (a bit high but I don't have a way to cool it more, but it is a constant temp) and I was unable to check on it until Monday and it showed signs of some fermentation, but Tuesday it had a foamy head and the airlock was bubbling. It did this for two more days and settled down. I checked the gravity yesterday (10 days) and it is only at 1.060. The following is the recipe that I used. HELP!!

first check that gravity again.... then if it is still shit add some dry yeast, you might be able so save it. Also taste your sample to see if you are good.

I tated it and it tasted good, just way to sweet. I was going to check it again later today. What about rousing the yeast that are in it? I was thinking about another vial of WLP001, but you think adding dry?

Try and rouse it... but if that dosen't work I would try dry yeast, it seems to handle "adverse" conditions better than liquid.
