The oldest form of barbecue, coming from the Spanish colonies we spoke of earlier, in the eastern part of the United States, has been widely known to be the first type of variation since it was brought from the Caribbean islands. The first form of barbecue we will look at it is known as Carolina Style. The style that has been formed in the North Carolinas and Virginia is known for using the whole hog when roasting, and using a thin sauce that is a mix between vinegar and spices. It's believed that the British first thought of using vinegar on the hog, as they had an affinity from their Homeland for tart sauces.
