Stuck fermentation?
« on: January 09, 2013, 09:01:56 AM »
Brewing a British bitter using Wyeast 1098

OG: 1.059

Temp: 66-68F

8 days passed and there appeared no activity and I was at 1.030

I aerated it by shaking and after 2 days I am still at 1.030

Pitch another pack of 1098 or...?

Thank you

Are you using a hydrometer or a refractometer to take your readings?  I'm just making sure you have done the corrections that are need for using a refractometer.  Using the reading you gave us, if you used a refractometer, you are sitting around 1.011-1.011. 

If you used a hydrometer, can you post the recipe and your process?  That can help generate ideas from the gang.

Thanks!

Where the heck are we going?  And what's with this hand basket?

Good catch! Thank you.

A refractometer.

The first time I've used it :-)

Seems I am good to rack then?

Is there a calculator that I may refer to so that I may compensate for the alcohol in the liquid and still get a reasonably accurate reading?

Cheers! (literally, now ;-)

IME and depending on the quality of the refractometer, even with proper conversion there is still a possibility of an off reading, best to use a hydrometer when checking for FG IMO.
