I have SoFlaQuers in the fridge all the time, seems to last weeks no problem, never seems to last longer than that though, bottles always end up empty! Make a double batch if you can.
As a side note, I completely over cooked/smoked a venison front quarter, cut, tugged, pulled it off the bone, tasted it, it was dry, added SoFalQuers and by the next morning everyone that tasted it said it was veni-crack!
That finishing sauce is outstanding in my opinion.
Godspeed,
