The journey from vine to glass is a matter of science and circumstance. There are a wide number of species of vines which bears a variety of grapes, known as varietals. For instance, the Chardonnay grape is green and produces white or ‘blanc’, Chardonnay wine. Each varietal, affected by soil type, climate, wind, farming practices and other factors, produces various characteristics. In South Africa, it is not legal to add flavourants. As such, when Chardonnay is said to exhibit vanilla, for instance, certain winemaking processes might exhibit that character. For example, aging, or maturing wine in wood can produce certain tastes and smells.
