Nutrients Needed from Vine to Wine

It may be an obvious statement, but for a vine to grow and for grapes to ripen, adequate water and nutrients are required. The nutrients required are predominantly found in the soil. The good news is that vines themselves require pretty low levels of nutrients. However, those nutrients do get depleted by viticulture, so that’s why grapegrowers are constantly testing their soils and monitoring nutrient levels.

Why Vineyard Slopes & Aspect Matter

[Information based on DipWSET D1 material]

Steep hillside vineyards in the Mosel-Saar-Ruwer region in Germany produce outstanding Riesling wines. Germany is reveling in a raft of young producers, people like A.J. Adam and Florian Lauer, as conversant with dry styles as they are with sweet. Photo: German Wine Institute

IF all other factors were equal, regions at lower latitudes (nearer the Equator, like Mendoza, South Africa, New South Wales) will receive more solar radiation per annum than regions at higher latitudes (nearer the Poles, like northern France and Germany).” But we know that “all other factors” are not equal are they? Where a vineyard is planted within its give region has more specific influence than just the mere latitude it happens to reside. To make this point, I’m going to be looking at the Northern Hemisphere—specifically cooler climate regions of the Northern Hemisphere. So travel with me, if you will, to your favorite cool climate wine region. (I like Alsace, but whatever you fancy.)
