Ripening is the third stage of Grape Development. Starting from the top…
During grape berry formation—the first stage of Grape Development— malic and tartaric acids begin to accumulate, aroma compounds and precursors begin to form (also check out Aromatic Compounds post), tannins start to accumulate. But the grapes themselves are green and quite bitter—very little sugar has accumulated at this point.
Another interesting anecdote is that water flow is quite high during grape berry formation, but too much water and nitrogen (please also see Stuck Fermentation to learn about soil nutrients) can prolong this phase, as it will encourage green growth, not grape growth. So “mild” water stress is the way to go here.
Veraisonis considered second stage of Grape Development. This is when grapes begin to change their color, skins become more supple, stretchy. But regarding the grape growth, it actually slows down. This phase is what many viticulturists refer to as a “lag phase.”
Last week I participated in a webinar, discussion, and virtual tasting highlighting the Paso Robles AVA through the eyes of three prominent winery representatives: Jason Haas, partner and general manager of Tablas Creek Vineyard; Jordan Fiorentini, vice president of winemaking and vineyards for Epoch Wine Estates; and Amanda Wittstrom Higgins, newly appointed executive vice president of Ancient Peaks Winery.
The main takeaway (at least to my eyes and ears): Paso rocks. I mean, yes, it rocks in the figurative sense as well. But I was really digging (pun sort of intended) all the geeky geological stuff these guys got into. The show-and-tell of vineyard rocks was one for the record books. Have you seen fossilized whale bone in your backyard? Thought not. And of course, how these soil types and topography of each vineyard’s location affects the wine style is a connection I love making.
So, I thought I’d take some time to talk a bit about each winery, why they “rock,” and of course include mini wine reviews for each. Please, enjoy.
Napa, Calif.—The Napa Valley Farmworker Foundation (FWF) and Napa Valley Grapegrowers (NVG) announce a partnership with St. Helena Hospital Foundation (SHHF) to increase access to COVID-19 screening for farmworkers. NVG and FWF have jointly funded supplying and staffing a mobile health unit, capable of traveling to vineyard sites and testing up to 100 vineyard workers per day. These funds have secured an initial order of 3,000 tests to be made available throughout harvest to vineyard workers.
“The St. Helena Hospital Foundation established the Mobile Health Unit to provide accessible medical resources to the community. We’ve worked on the project for over a year and to see it used in this way, to provide COVID-19 testing support for our agricultural workforce through the Napa Valley Grapegrowers and Farmworker Foundation, I couldn’t be more proud,” said Karen Cakebread, Director for the NVG and SHHF, who helped launch the mobile testing effort, “It is exciting that the synergy between the organizations came together at a time when our community needs creative solutions and quick action to support our work force.”
Since the pandemic was declared in March, the FWF and NVG have dedicated over $200,000 to provide comprehensive safety resources in Spanish and English, social distancing vineyard signs, cloth face masks to over 10,000 farmworkers, and recently launched a statewide bilingual community education campaign via the FWF COVID-19 Task Force. Providing critical access to testing is an important piece to ensure the continued health and wellbeing of Napa’s farmworkers. With the Mobile Health Unit launched, NVG and FWF continue to develop plans for increasing testing capabilities and opportunities in the community, to prevent COVID-19 and keep workers safe.

If you’ve been sticking with me through my WSET studies, you’ll know that the last two posts were all about soil types and soil health. In keeping with that theme, I want to highlight a new-for-me winery, Notre Vue Estate from Windsor, California whose latest releases dive into the soil types and structures throughout their vineyard.
As I talked about in my Vineyard Soil post, it’s not just soil composition but vine row orientation—i.e. slope and aspect—that dictate what vines will thrive best where in the vineyard. So, let’s take a look at what viticulturist Daniel Charles has to say about the Notre Vue soils and then have a little taste of what those soils have produced…
Six ways growers can manage the health of vineyard soil.
In our last exciting episode of WSET studying, we discovered the world of soil and left off acknowledging that there are loads of tests that growers can conduct before a vineyard is established to understand the composition and overall health of his/her/their potential vineyard. Just as important are regularly scheduled tests—think of it as your vineyard’s annual checkup. Soil health tests can indicate what, if anything, needs to be improved—be it the structure, nutrient level, water availability, or pest management.
