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!

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.
