Although some will list about 4 to 12 or more, the top “tier” of types of barbecue sauces are 2. There are tomato-based and vinegar-based BBQ Sauces. Some will add-in mustard-based BBQ sauces but those are merely vinegar-based as well. Others will convey there are some speci�c geographical types such as Carolina, Texas, Memphis, etc. But, the top tier of 2 types (tomato and vinegar) remains as the standard and the geographical locations will merely have their regional versions of those 2 types. Usually, people will trend towards one of those 2 types of barbecue sauces without being aware. Geographically, as an example, people in the Midwest will lean more towards tomato-based BBQ Sauces. While, people in the South will focus on the vinegar-based BBQ Sauces. However, both types are worldwide favorites, as this is a matter of personal preference, and often is based on what was given most frequently when growing up. As we are given choices, some will then be exposed to a variety and our tastes change. There are also some foreign sauces that equate to their acceptance as a “BBQ sauce”. One example is Korean BBQ Beef (or Pork). They use a soy sauce based marinade and adopted a similar reference to our BBQ sauce as they also sometimes brush it on during grilling.
