Oenology (BrE) or enology (AmE) is the science and study of all aspects of wine and winemaking from the grape harvest to bottle. An expert in the field of oenology is known as an oenologist, but can also be a winemaker.
The name is derived from the Greek term, oenos (οίνος), which means wine, and the suffix -logy (from the Greek λόγος, meaning speech or study).
Viniculture : The cultivation of the vine, esp. for making wine;
Viticulture (from the Latin word for vine) refers to the cultivation of grapes, often for use in the production of wine. When the grapes are used for winemaking, it is also known as viniculture. It is one branch of the science of horticulture.
Viticulture is the science, production and study of grapes which deals with the series of events that occur in the vineyard. Grapes are grown for fresh fruit, dried fruit or for the grape juice, which can be used (amongst others) to produce wine. Duties of the Viticulturalist include: monitoring and controlling pests and diseases, fertilizing, irrigating, canopy management, monitoring fruit development and characteristics, deciding when to harvest and vine pruning during the winter months. Viticulturalists are often intimately involved with winemakers, because vineyard management and the resulting grape characteristics, provide the basis from which winemaking can begin.
