DipWSET Theory: 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.

DipWSET Theory: Why Vineyard Slopes & Aspect Matter

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.)

DipWSET Theory: Flowering and Fruit Set

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…

This Week’s Latest Wine Headlines: June 28—July 3

It’s a short week this week for those of us in the US, and I hope everyone has some way they’ll be enjoying the time off. Of course, celebrating our country’s heritage is a bit bitter sweet this year—for many reasons—so, I’d like to highlight a few positive pieces that came out in this week’s wine-related news. Wine Industry Advisor speaks to Sonoma viticulturist Brenae Royal, who speaks to how racial inclusivity within the wine business means creating a simultaneously broader, yet more intimate and meaningful, wine consumer base. For more on that kind of perspective, check out the Forbes piece that profiles three Black wine experts—including one of my favorite local producers Theodora Lee. And for those of you in the biz who are looking to hire, work or network with, or just become familiar with qualified Black wine industry pros, Julie Coney has spearheaded, and officially launched, the Black Wine Professionals website just this past week.

Need a bit of a laugh? Well, there’s a company making wine bottles out of paper. Yeah…

Oh, and for my wine nerds out there, check out Tim Gaiser’s blog post on deductive tasting and Young Gun of Wines’ dive into ageable Aussie Chard.

That’s some of the good/fun news. However, I do want to say that if you have outdoor plans for this Fourth of July weekend, please stay safe. Here in California Newsom has shutdown indoor businesses (including bars, restaurants, wineries, and tasting rooms) in 19 counties, as well as state beaches from Monterey to Sonoma. But before you get any ideas about packing up the truck and heading toward the North Bay, be warned: Sonoma County is not immune and is, in fact, probably next on that list.

So, again, wherever you are, however you choose to celebrate, please make smart decisions, stay safe, protect yourself and others. That’s all from me for now. Have a happy weekend and drink some good wine.
