|My wife and I love really tangy tomatoes. I would like to know which varieties have the highest acid content.|
|According to the University of Minnesota Extension, "a lot of misinformation has been printed in the popular press about "low acid" tomatoes, referring to those with a sweet, non-tart taste. These tomatoes are often white, yellow, or pink in color but are not low in acid content. The higher sugar masks the acidic flavor."|
The goal, then, might be to find a relatively low sugar tomato, rather than a high acid one. Some people say that the older varieties of tomatoes--the "heirlooms"--have the best taste (examples include Amish Paste, Mortgage Lifter, and Black Krim.) And I've noticed that yellow, orange, and pink varieties are often described as mild-flavored. So you might want to try a few plants of some of the older varieties, especially those described as having deep red fruits, and do your own taste test. I suggest you also plant at least a few of the newer, disease-resistant hybrids as well, because the old varieties are often susceptible to common tomato diseases.
