If I may, for those that don't live in a BBQ region, and if you're in the UK you don't, there is no substitute for making your own BBQ sauce. Google recipes and experiment. Nothing you get from a bottle will compare! Nothing!
Being a Texan and having grown up with some of the best BBQ in the world, I can assure you that I never buy any brand of commercially available BBQ sauce. I either buy from local joints or I make it myself. There's no comparison imo.
Honestly, it's not that hard to make it yourself. After a few batches you'll know what you like and can tailor it to your taste. Tomato based? No problem. Vinegar based? No problem. Spicy? Mild? Medium?... anything goes.
Don't settle for SuperHyperMega commercial brands!! Do you settle for commercial BBQ? Lordy, I hope not.
