Tabasco sauce is a hot spice sauce. It is only used drop by drop. It is based on Tabasco chillies, vinegar, salt and other spices. The three-year maturing period in oak barrels gives the Tabasco sauce its typical taste. Tabasco sauce is available in different varieties and pungency grades, with the Habanero sauce being the most pungent. The second sharpest is the classic Tabasco Pepper Sauce. The Green Pepper Sauce, which is prepared from green chillies, has a slightly milder taste.
