I made a prickly pear memomel back in September 2017. O.G. 1.117. Racked three months later at only 1.112.
I have lost my notes as to the yeast I used, etc. I've been ignoring it, hoping I guess that it would slowly ferment.

Last week, I decided to see what was up. Gravity now at only 1.110. Super sweet, almost syrupy so. I added some Lavlin D47, and 1/2 tsp of yeast nutrient.

Still no activity. Any suggestions?
