Educated experts in wine are called oenologists and the comprehensive study of wine is called oenology. Oenology, also spelled enology, focuses on wine and winemaking and not on how the grapes are grown (viticulture). An expert in oenology is knowledgeable in grape varietals, fermentation technology, microbiology, aging, wine tasting, and other areas. Oenologists can be head winemakers in wineries, researchers, developers or winery owners. http://oenologist.org/ Many enologists are also experts in viticulture.
