Planting a new vineyard, replanting an old vineyard—where does that new vine material come from? There are a couple different options growers have, each with their own benefits and downfalls. Let’s take a look…
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.

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.)
Yo. Don’t ask why yo. Just yo. Yo—I gotta study for my WSET Diploma (D1) exam. One thing that really helped me pass my Level 3 exam was writing posts that simulated questions I could expect to see on the exam. So, that’s what the next (several) posts will be. Interspersed with wine notes (probably). My first exam is in one month. On my birthday no less. So…help me study? Thanks.
Let’s start with grape development…
