Stuck fermentation?

Post by Caddarn » Fri Mar 13, 2015 7:19 pm

About 12 days ago I made my first extract brew following this recipe - http://www.northernbrewer.com/documenta ... tish80.pdf

My OG was slightly higher at 1050. I chucked the hydrometer in this morning and its showing 1020/1022 which I thought was a bit high. I gave the bucket a gentle rotation on it's bottom edge to see if it would rouse the yeast but after 9 hours it's still around the 1020 mark. I admit to using slightly more liquid malt than the recipe listed (2 x 1.5kg as opposed to 2 x 1.42kg) so could it be the single packet of dry yeast couldn't handle the extra sugars?

Not really wanting to bottle with the gravity so high but I suppose if it's done, it's done!

Just looked at the link and wondered if you went for the Windsor yeast?

Would it be worth pitching another sachet of yeast?

It's a bit of a funny beast, it has an apparent low attenuation, but does have a bit of a reputation for carrying on very slowly, so may appear stuck or finished, but it actually still fermenting.

I gave the fermenter another gentle shoogle yesterday morning and tonight I have a fine layer of krausen on top! Looks like it's going to come down some more!
