Fortified black currant

[Marinus]

Hello.
I am making a fortified black currant wine and I'm having a weird issue. I fermented 3 gallons of black currant must down to taste (about 1.04). Then using an online fortification calculator, I added 1.5 liters of 150 proof everclear which had been infused with more currants (to about 20%). This should have killed fermentation and stabilized the wine. But for some reason the airlock is still bubbling, although very slowly. I was wondering if I didn't get the alcohol content quite high enough. The yeast I used (Lalvin K1V-1116) has a high alcohol tolerance. Has anyone ever had this issue? I'm hesitant to just add more booze, so maybe I'll have to stabilize some other way.

try some potassium sorbate and kmeta. maybe able to get the yeast to stop and die off in the alcohol environment.

Bubbling is a sign of CO2 coming out, not fermentation. Check the SG. If is is the same for 3 or so days fermentation is done.
