first mash is in a hurry it seems

[big blue nation]

hey i am new just got my still up and started a mash while i am cleaning it and doing my vinegar run...I an using wposw and it is doing good start sg 106, third day 102 , fifth day .99 it is still fizzing and bubling. my question is should i add more sugar at this point ..i also left out the epsom salt and added some fermax yeast nutrient from a wine and beer store..was that a mistake too.. I look forward to your feed back guys . It smells better than some shine i bought earlier this year just thought I'd throw that in there

Just wait for it to stop bubbling. At .990 it should be done anyways. Why do you want to add more choogur?

thought it would raise the abv since maybe the yeast was still working hard

That's done at the beginning not the end.................

If your hydrometer is reading 0.990 it is done(unless your hydrometer is way off calibration), you are probably seeing trapped gas escaping from the original ferment. You can degas it with a lees stirrer or a spoon but I'd only do that if you are ready to run it fairly soon. Also, adding more sugar now would be like step feeding it. You CAN do it but then you start the primary cycle all over and have to wait for it to finish again. If you do that you raise the ABV but eventually the yeast will just knock off due to too high ABV. Probably better to run it since it's done and save the sugar for future washes.
