Stalled MTN DEW Recipe

Recommended Posts

Hi  not many here any more. I read what's new and some old posts. Thought I would post my current issue here with a smaller group  other then HBT. Wont get lost in the mix

I brewed the subject recipe, used regular MTN DEW soda NOT diet.  OG 1.063 ferment 3 weeks in LBK  FG 1.030  WAY off per MRB. Yeast US-05.

I was going to bottle it but was concerned the high residual sugar would give me bottle bombs.  So I did the radical fix, add a pkt of CMRB yeast, stirred the trub increased temp from cold crash temp to 70, put back in fermentation chamber at 68.  After 2 days there is NO yeast/fermentation activity. I am guessing there is no fermentable sugars. The high readings are related to the other ingredients ? in the soda.   Plan is to wait a week then transfer to a 2.5g keg, add 2 oz of sugar, attach a pressure gage /CO2 charger and see what it does.   Aside, I keg about half of my recipes these days.

See if it self carbs in the keg then add CO2 to force carb it for drinking.

Taste sample was OK  a bit hoppy but good. 

Thoughts?

I've never brewed that one, but it sounds like you're on the right track.

did not think of that. It is sort of carbed  I only tasted the hydrometer sample. Was some foam in the sample. Well it  is not doing anything now, so keep to the plan, go 7 days  then keg it. Might condition OK. 

I also took a refractometer reading was 11, way  high also - should be about 4 to 6 - so both devices are affected by something. Both indicating high sugar content.  very strange.  Per MRB FG should be close to 1.009.. but I never get FG according to the MRB recipe sheets anyway.

Yes, I know refractometer is not accurate with alcohol content...

thanks

After 7 days of no action after I added a pkt of MRB yeast, I decided to keg the batch. I added 2.25oz corn sugar to the keg and filled it with the beer from the lbk, used bottling wand to reduce 02  ingress.  FG was 1.029.  Should be 5.2% ABV.  I kegged in case it took off after priming. Kegged 10/3  -so far the pressure has not increased above the base of 15 psi.  I 'bottle' all my kegged beer vs forced carb.  If the process works I should see a increase of  keg pressure. I plan on letting sit for 2 weeks to condition, same as I would with bottling. Then move to cold and increase CO2  to 20 psi for another week.  Hydro sample tastes OK, It will be a drinkable beer.. More to come

I wonder if residual carbonation from the Dew is causing an inaccurate FG reading.

 

Too late, but the sample should have been degassed.  Basically cover the sample tube, shake it like crazy, and let the gas come off the sample, repeating until it's flat.  Then test it.  

 

Of course it could just be the beer gods punishing the OP for making beer with Mountain Dew.
