Oops! Gravity reading after priming

Post by UmBongo » Tue Jan 22, 2008 10:11 pm

Got a bit cocky and siphoned a Geordie Bitter into a keg assuming fermentation had finished - also primed with 65g of castor sugar.

Anyway, curiosity got the better of me so I took a hydrometer reading which came in at 1016 (was expecting ~1006). Can this whole 10 points be because of the 65g sugar (i'd assume some of it would be)? Also, does using beer enhancer result in a higher then expected FG then using brewing sugar alone?

Cheers

When you make an assumption you make an ass of U and mption :).

I don't think 65g of sugar in 5 gallons could make a 10 point difference when 3 kilos make 40. I would say you might have had a stuck fermentation. I would keep a very close eye on it and make sure it doesn't over pressurise in the keg but otherwise don't worry too much and if it tastes good then drink it.

Assuming your brewlength was 23l beersmith says that adding 65g sugar will increase the gravity by 1 point so it looks like you kegged at 1.015.

Beer enhancer is not as fermentable as table / brewing sugar so the gravity will be slightly higher than you'd normally expect if you make the kit up with a kilo of sugar, although that said I'm not sure if it would be as high as 1.015.

If your keg has a pressure release valve then you should be fine, If you've bottled any then you may want to release the pressure and recap

Thanks for the quick replies chaps.

I was planning on bottling some but changed my mind when I saw the
reading. Hopefully it will ferment down some more in the keg - it has a small rubber ring on the cap which I believe to be a pressure release thingy.

The important thing is that it tastes surprisingly good straight out of primary :)

Well that's certainly a result in my book

Don't thank me thank Samuel L. Jackson in The Long Kiss Goodnight. I was just quoting him. :)
