Slow Yeast and / or no evidence any fermentation
« on: August 27, 2012, 04:46:45 PM »
I brewed a Belgian Wheat IPA on Friday (8-24-12) from the kit the Austin Home Brew.  My OG was 1.070 which was on target and I pitched 2 WYEAST Belgian Strong Ale 1388.  Fermentation started within 12 hours and was kicking until this morning.  I opened up the carboy and there was no evidence of any real noticeable fermentation as the top fermenting yeast cake I guess had begun settling to the bottom.  I took a gravity reading and it was at 1.028.  It has only been 3 to 3/12 days since I brewed this batch.  Is there reason to be concerned?

Here is the recipe:
7lb Belgian Pilsen Malt
6 LBS White Wheat
1/2 lb Aromatic Malt
1/2 lb Flaked Wheat.

Mashed for 1 hour at 154 then mashout for 15 minutes at 168.  Fly Sparged for 1 hour using 170 degree water.  60 minute boil.

Thank you in advance!

was the fermentation temp steady? What temp did you start the fermentation at? What temp did you hold the fermentation?

I have a swamp cooler set up.  I pitched the yeast at 69 and it has hovered the entire time between 71 and 73.

I have an IPA right next to it in another carboy with the same swamp cooler setup and its temps have remained just like the Belgian Wheat IPA

How are you measuring gravity? Hydrometer or refractometer?

I don't think there is anything to worry about. it's only been 3.5 days you say. I think it's still working. take another reading in another 2 days and if it is still at 1.028 then start worrying.

Hydrometer
You are certain the hydrometer was floating and not touching the bottom of the tube right?

I typically don't pull a sample.  JUst drop my sanitized hydrometer into the fermenter and take a reading.

If there is still alot of co2 disolved in the beer it's going to cling to the hydro and lift it up a bit. Take a sample, degas by shaking or pouring back and forth from one vessel to another and then take a reading. I don't think it would explain 20 points but it might well knock of 5 or so points.

OK. Then I'd recommend patience. Worry if it hasn't changed in a few days.
