Etymology: Before it came to English as a technical term in winemaking and oenology, the word mustum was a Latin noun meaning "new wine" or "freshly pressed grape juice." In Roman times, mustum referred specifically to the sweet, unfermented juice that had just been extracted from grapes, before the onset of fermentation. This early usage captures the essence of what the substance really was: a raw, natural liquid at the very start of the winemaking process. The Latin term likely derives from an older Italic root, related to the idea of freshness or sweetness, though exact origins remain somewhat uncertain. The Romans valued mustum not only as the precursor to wine but also as a drink in its own right, sometimes boiled down to concentrate its sweetness into a syrup called defrutum or sapa. This practice appears in classical texts and recipes, highlighting the practical and culinary importance of mustum in antiquity. Its entry into English and other modern European languages is quite specialized, mostly through scholarly and technical contexts rather than everyday speech. During the Renaissance and later periods, as interest in classical texts and ancient viticulture revived, mustum was borrowed directly from Latin by wine experts and botanists to denote the freshly pressed grape juice still rich with natural sugars, not yet transformed by yeast. This term remains a niche but precise label within viticulture and enology, preserving the connection to its Roman heritage. Unlike many wine-related words that evolved through Old French or Italian, mustum’s usage in English is more of a direct classical borrowing, reflecting the scientific and historical lens through which we study winemaking traditions today.
