Rum Wash Ferment Concern and Issue

[Grayp]

I made a 5 gallon rum wash that started off great with lots of fast burst nonstop bubbles and on day 5 completely shut off.



The recipe was:

· Brown Sugar – 6 lbs.

· Molasses – 24 oz.

· Multi Vitamin -2 crushed and dissolved

· Yeast Nutrients – 1 tablespoon

· Epson Salts – pinch

. Lemon Juice - 2 Tsp (since I have no Dunder)

· Banana Peel - 1

· 2 packets EC- 1118 (the yeast was hydrated per the packet instructions prior to being pitched)


The starting readings were:

· Spec Grav Starting - 1.085

· Potential Alcohol – 11%

· Sugar Content – 20%


The wash temp was about 80 deg F when the yeast was added and it started at a medium bubble rate. The next morning it was 78-79 and bubbling nonstop in fast continuous bursts.

The temp was held steady and on day 5 the wash stopped and the temps 74 deg F. I shook the bucket and it started up again, very slow (1 bubble every min)



What’s going on? It’s not an air leak in my bucket lid or bubbler since if I apply a little pressure to the lid the bubbler works.

Is it a temp issue?

or is my recipe totally off?

Is it a yeast nutritional issue?



Thanks for your thoughts
