High spring water in Diamond Creek - great start to the growing season

Finally, Diamond Creek is flowing again- and the start to a new growing season is promising!  After a very dry February, we received 15” of rain in March.  Budbreak took place the week of the 21st- early, but about the same as last year. This potentially sets us up for another early harvest, but  now at least we have plenty of soil moisture going into the Spring-- which the vines need in order to grow canes- they'll grow about 1 meter over the next couple of months. We hear Diamond Creek roaring these days as it flows between Dyer Vineyard and the famous winery to which it lends its name, is roaring today. (Probably hard to read in the photo here, but the year 1885 on the bridge shows there were people making wine in the neighborhood way back then). Stay tuned for updates as we progress through the 2016 Vintage in the Diamond Mountain District, Napa Valley.

Managing tannins is key

Managing tannins is key to making wine on Diamond Mountain- all those lovely aromas and flavors can be overwhelmed by hard mountain tannins if not managed properly.  And like most things in winemaking, that management starts in the vineyard.  We are already doing tannin management for the 2015 Cabernet Sauvignon. We recently removed excessive shoots (shooting, so to speak, for 15 shoots per meter), so that the clusters will ripen in an environment of dappled light rather than shade. We are following the wisdom of Goldilocks when it comes to sun exposure: not too much, not too little, but just right. In excessive shade, the skin tannins will be like sandpaper in the mouth. If there is sunburn, they will not form at all. With just the right amount of light they will become supple and plush, and do so in a timely manner—that is, before the sugar levels get too high. High concentration of sugar (aka “brix”) directly leads to high alcohol, which in turn destabilizes tannins (and may destabilize us  end users as well) . But it’s not all about us—the vines’ goal is to produce berries with juice sweet enough to attract birds, without assaulting them with bitter and astringent compounds in the skins and seeds. In nature the birds then help propagate the vines by dropping the seeds (it is considered lucky to get hit)!

Soon we will be cluster thinning—leaving no more than two clusters per shoot. Managing yield involves the balance between leaves and fruit , which affect the rate of ripening. Pulling leaves in the fruit zone helps too—but again this is a matter of balance (remember the goal is dappled light). Later we will be green thinning—removing clusters that are slow to turn color, so as to promote an even ripening.

The decision of when to pick is a critical part of tannin management. In the past the focus was on achieving a target brix level. Now we realize that brix and tannin do not necessarily ripen at the same rate.  As green seeds are reservoirs of harsh and bitter compounds, we observe and taste the seeds, picking after they are brown and crunchy—like “grape-nuts.” Lucky for us that  on our site tannins are ripe at relatively low brix, as the last, critical stages of ripening occur slowly in the cooler and shorter days of fall. On a more sun-exposed site, sometimes the sugar accumulation runs ahead of tannin maturity.

Forty years ago when we came to the valley, these practices were not common. Growers were anxious to rush grapes to the wineries when the target brix level specified in the contract was achieved. Migrant workers often arrived just in time to pick the fruit, making intensive hand-work difficult to achieve anyway. Now we realize that throughout the season we must keep our eyes on the prize: supple, rich, plush tannins.  As you can see, this is an ongoing obsession!

Earth Day, Napa Green

Hooray! Just in time for Earth Day, Dyer Vineyard has received certification by both Napa Green and Fish Friendly Farming. Both these organizations work closely with vineyard owners and wineries to develop specific practices for their sites that will protect and sustain our land and watersheds. Napa Valley Vintners recently set a goal of having all of its members (currently 500 and growing) certified Napa Green by 2020. The certification process looks at the entire property, including roads, in developing each individual plan. With terms such as organic, sustainable, and biodynamic becoming a little fuzzy, it is great to work with these two certifying organizations to lay out programs that are both specific and locally focused

Announcing the Release of Our 2012 Dyer Vineyard Diamond Mountain District Cabernet Sauvignon

On April 16 we will release our 2012 Dyer Vineyard Diamond Mountain District Cabernet Sauvignon. Only 252 cases were produced from our 2.3 acre vineyard—they will be first offered to our mailing list customers.

The 2012 vintage is already being described as a classic vintage for Napa Valley  Cabernet Sauvignon.  In March over a foot of rain fell on our site adjacent to Diamond Mountain Creek. The deep gravely volcanic soils on a gently sloping bench welcomed the long drink, and the vines budded out the first week of April. The remaining spring weather was warm, dry, and frost free, leading to an even fruit set, with all the clusters on the same ripening curve. The summer was warm and mild, with temperatures in the 80’s and 90’s, often dropping into the 40’s at night, conditions favoring development of flavors while retaining acidity.

All in all, it was a wonderful season, and a return to normalcy after the challenges of 2011. So mark your calendars for April 16, and get ready to celebrate a new classic vintage of Napa Valley Cabernet Sauvignon!

Tahiti Cruise

On one of the few rainy days we’ve had here in the Napa Valley this year, I’m day-dreaming about a cruise.  And not just any cruise but traveling to the South Pacific- Tahiti, Bora Bora and Moorea, to be specific.  Years ago Bill and I had a chance to sail on the Paul Gauguin, a small ship specially designed to navigate the aqua waters of Tahiti and named for the painter that first brought it's exotic beuaty to the attention of France and later the world.  It was one of the most gorgeous, visually stimulating, and serene experiences of our lives- and something we’ve longed to do again ever since. 

tahiti cruise

Now the chance has arisen again- this time we’re sharing it with great pals Joel Peterson and Mady Deiniger, their wines from Ravenswood, and our wines from both Dyer and Meteor Vineyards.  And we’d love to have you join us.  We’ve got it figured out so that we’ll all have glorious days on the ship, in the water, and on the beaches with time to sip and swirl our wines together at seminars and dinners.  We’re packing older vintages and big bottles and have been talking to the chef about menus and pairings.


Oh, and did I mention that we’re going for New Years?  December 30, 2015 to January 6, 2016.  Bliss!  If you’d like to join us, see all the details at Food and Wine Trails.
