They retain large amounts of tartaric acid (which few microbes can metabolize, giving yeast a competitive advantage), ripen with enough sugar that the resulting <a href="https://kvalifood.com/wiki/alcohol-science/">alcohol</a> suppresses nearly all other organisms, and offer striking colors and a diversity of flavors. Seventy percent of the world&rsquo;s largest fruit crop goes to wine.</p> <h2 id="why-grapes-are-special">Why grapes are special</h2> <p>Most fruits ferment readily, but grapes do so with unusual reliability and quality. Tartaric acid creates an environment that favors <em>Saccharomyces</em> yeasts over spoilage bacteria. The sugar content at ripeness (typically 20–25%) produces 10–14% alcohol — enough to preserve the wine without any additives. The vast number of grape varieties, each responding differently to soil and climate, explains wine&rsquo;s infinite regional diversity. Pliny noted in Roman times that the same grape produced different wines in different locations — the concept now called terroir.</p>
