Sour: tart, tangy, acidic, old-fashioned, tomatoey, assertive, bold, citrus.Sweet: sweet, fruity, tropical, sugary, low-acid, refreshing.When texture detracts from the flavor, a tomato is often referred to as mealy.įlavor, we might say, is in the chemistry of the fruit. Greenhouse and determinate tomatoes-often with fewer days to maturity and thus fewer days of exposure to sun and thus the development of sugars-are firm. Heirloom vining tomatoes often have a pulpy texture that is associated with old-fashioned flavor. Texture or “mouthfeel” can affect tomato flavor. Volatile signals sent from the back of the mouth interact with taste signals sent by the tongue in various parts of the brain to create flavor.) (Volatiles are sniffed through the nose as we chew food-they enter the nasal cavity from the back of the mouth. The fragrance of volatile compounds or oils in fruit cells-while neither sugars nor acids (they include amino acids, fatty acids, and carotenoids–pigments)-contribute to the perception of sweetness independent of sugar concentrations. Tomatoes with low sugar and low acid levels are often described as bland or mild. Tomatoes that are high in acid and low in sugar are described as tart or tangy. Tomatoes described as sweet contain high sugar but low acid content. Traditional tomato flavor-preferred by most people-is a nearly 50-50 combination of sugars and acids this is often referred to as “old-fashioned” tomato flavor. A tomato low in sugars and acids has a bland taste.
A tomato high in sugars and low in acids has a sweet taste. Often tomatoes are classed as sweet flavored, acidic or sour flavored, or balanced. However, environmental factors-the amount of sunlight, nutrients, and water a plant receives as the fruit develops-can affect fruit sugar concentrations and the development of volatile substances
The number of sugars, acids, and volatile compounds in a tomato can vary by variety and are mostly genetically determined. (One tomato can have more than 400 volatile compounds.) There are 15 to 20 assertive volatile compounds in a tomato.

Aroma is integrated with taste to create full flavor. Volatile compounds or oils in the fruit which are released as a fragrance when the fruit is crushed during eating contribute to flavor. Acids in a tomato-mainly citric and malic acids-result in a tart, sometimes sour flavor. Sugars in the tomato-mainly fructose and glucose-result in a sweet flavor. Tomato flavor is sometimes also described as “classic tomato flavor” or “old-fashioned tomato flavor.” And the flavor of some tomatoes is described as mild or bland.
Tomato flavor is commonly described as sweet, tart, tangy, or balanced. Simply put, the human perception of tomato flavor involves the integration of taste and smell. Tomato flavor is a balance of acid and sugar recognized by the tongue and the effect of volatile compounds within the fruit that cause aroma recognized by the nose. Tasting peak-season, just-picked tomatoes each summer is the best way to come up with your short list of tomatoes to grow next year. Getting to know new tomatoes and their tastes will bring added pleasure to kitchen gardening. Once you have identified your favorite tomato (or tomatoes), the memory of that fruit’s flavor will easily get you started in spring and keep you going until harvest year after year. Flavor is probably the best reason for selecting a tomato for kitchen garden growing.
