Kansas City's Cowtown Night Of The Living Barbq Sauce, Rev. Marvin's Original or Hot, Blues Hog Original and Tennesseee Red, Bone Suck'n Sauce, and the others generously cut with apple cider vinegar.
I helped make 30 gallons of sauce for our church BBQ last week and it was Cattlemans with vinegar and a lot of spices - NC Piedmont sauce.
