Syrah show-off.

Seven days on, the Syrah grapes are progressing through veraison quite nicely.  A bit more advanced than the rest of the Syrah, this specific vine has always been a bit of an overachiever.
One of the original vines planted in Vinoland (circa 2000), the scion (Durell clone) was grafted onto 110 Richter (berlandieri x rupestris) rootstock.  Arguably the worst rootstock for the soil type in Vinoland, tuff and clay, the 110R-grafted vines eventually failed and the Syrah block had to be replanted.  The replant, though, was to 101-14 Millardet et de Grasset (riparia x rupestris), a much more suitable rootstock. There are approximately eight vines surviving from the first planting, my little poser vine being located in a particularly poor area of soil, I mean shockingly bad. Regardless, the vine seems to have tapped into something it likes below ground and it continues to thrive.  Crazy teenager.

Dr. Frank.

The next book, in my personal quest to understand more about the history of Vitis vinifera in the United States, is this book by Tom Russ: Finger Lakes Wine and the Legacy of Dr. Konstantin Frank.
Dr. Frank was by all accounts a bit of a poop disturber; in that he tried to shake up the New York state wine industry by repeatedly insisting that V. vinifera, i.e., European winegrape varieties, could thrive in the eastern United States.  It is in Dr. Frank's expertise as a viticulturalist, and his scientific approach to clonal selections, that I am mostly interested in.
Love wine-history.

True Wine Lover 17.

I have just finished reading Vineyards in the Sky a biography about pioneering California vintner Martin 'Rusty' Ray.  The book, which reads like a novel, was written by his second wife Eleanor (herself, in a small way, a contributor to California's wine history - y'know, behind every successful man...).  It tells of the interesting life of Martin Ray; a man whose persistence, and passion, in championing for strict varietal wine regulations, and the establishment of identifiable viticultural areas in California, made him quite a controversial character.  And, nowadays, hardly anyone in California has ever even heard of Martin Ray.
Martin Ray, a protégé of Burgundian transplant Paul Masson, railed against the production of cheap blended wines - wines whose producers then passed off, onto the unsuspecting consumer, as varietal wines.  (Let me just say, Ray despised Thompson Seedless grapes.)  In 1936, Ray purchased Paul Masson's La Cresta vineyard and winery (2000 feet up in the Santa Cruz mountains).  Six years later, after selling La Cresta to Seagrams, he developed his own vineyard on another crest to the northwest: his very own vineyard in the sky.
Ray made a bit of a nuisance of himself by insisting that California vintners should make 100% varietal wines - wines that he believed could compete with any of the wines coming out of Europe.  He was a bit of a stickler.
Martin Ray was also perhaps one of California's earliest advocates of the use of clonal selections in winegrowing, himself identifying and then propagating Pinot Noir and Chardonnay clones that were originally brought to America by Paul Masson.  Interesting reading - if you're a vine-geek like me.
Today, June 26th, would have been Martin Ray's 112th birthday.  Happy birthday Rusty!

To bloom betimes.

I think 2016 is going to be an unusual vintage.  I say this because today, whilst I was out in the vineyard stuffing shoots, I noticed that Vinoland's Cabernet sauvignon (CS) is further along in bloom than the CS at TWWIAGE.
It is fun to live (and farm) in a relatively cool AVA e.g., Coombsville and work (and observe) in another, noticeably warmer AVA e.g., Oakville. And why do I consider this year's earlier bloom, in spite of a cooler-than-normal spring, unusual?  Because from my personal experience, CS, Clone 4, in Coombsville is normally a bit of a slowcoach in the flowering department.  This year my little mutants apparently want to get an early start.  Go little girls and boys!

Each to their clone.

Lately, (if almost two years to the day can be considered lately), I have become very interested in the different characteristics that can be attributed to specific clonal selections of Vitis vinifera.  But what exactly is a clone?
Hortus Third offers this definition of a clone: "A plant propagated by asexual or vegetative means, including divisions, buds, cuttings, layers etc...Clone is a horticultural rather than a taxonomic term."
In regards to the grape/wine industry, a clone is a variant of a grape variety that is unique in some detectable way, whether by changes in the way a grapevine expresses a particular gene, or minor mutations in the grape variety.  Each clone, in this case let's say a clone of Cabernet sauvignon (CS), will taste like the parent variety, but with slightly varying characteristics, e.g., higher acidity, more concentrated fruit, firmer tannins.  Nowadays, it is common practice for growers, and winemakers, to utilise a variety of different clones, much like a cook will select different herbs and spices, to achieve certain flavour profiles in a finished wine.
The fact that I am interested in geeky viticultural goings-on would not come as a surprise to anyone who knows me.  But something that surprised me was the scarcity of information available about this particular subject matter.  I discovered this (yes, almost two years ago), when I attempted to do some research prior to purchasing some grafted grapevines to fill in the spaces where several vines had died in Vinoland's CS block.
There is a lot of anecdotal information to be had by talking to folks who are interested in viticulture, but a lot of it is useless.  Just recently, an acquaintance of Vinomaker mentioned to him that he thought CS clone 169 was a great clone to grow in the Tundra (aka Vinoland, Coombsville AVA).  I happen to be familiar with this clone, as Vinomaker used to make wine for a couple we know who used to grow this particular clone.  Clone 169 did indeed ripen in a timely fashion in Coombsville.  It is a pity we have clone 4 (a veritable retard, in the nicest possible sense of the word) planted here in Vinoland, (and oh, how I wish we didn't).  But it is what it is.  The little bit of information on clones that is available in written form comes from research conducted by John Caldwell and Anthony Bell of Bell Wine Cellars.  (Hmmm, perhaps someone should seriously consider compiling a reference work.) I eventually settled on clone 337 for my replants.
As for the wine in the photograph, this CS claiming to be made solely from clone 337 was an unremarkable, quotidian quaff.  To be fair, I did not do a comparison tasting of this wine with another made from a different clone.  However, I have comparison-tasted in the past; I have tasted clone 4 (Vinoland), clone 7 (St. Helena Sots) and clone 169 (North Avenue Negociants) side by side and they were quite distinct from one another.
Interesting stuff, I need to know more.

Gaudete, 2015.

It's Gaudete Sunday.  As is the tradition here in Vinoland, the wine of choice for the third Sunday of the Advent season is always something pink.  I have to say, I am absolutely tickled pink with my wine selection this year. (Sorry, couldn't resist).
The Richard Grant, NV Cuvée Rosé Brut (North Coast AVA) may not be the best California sparkling wine I have ever had, but it is definitely a very pleasant tipple.  And it may not be the bubbliest methodé champenoise wine that I have ever had: this Blanc de Noirs has the level of fizz one would more commonly associate with a Crémant.  The nose is delicately floral, the mouth-feel is balanced and the sour-cherry-strawberry-red-apple-skin thing on the palate is quite moreish.  Whilst this sparkling wine may be average, the story behind this wine is anything but average.
Grant is the middle name of  Dr. Richard Peterson.  Dr. Peterson may have had one of the more storied Napa Valley wine industry careers, but now he owns, and farms, a Christmas tree farm just north of the city of Napa.  Dr. Peterson is the winemaker of my 2015 Gaudete rosé selection, a wine he produces from 2 acres of his property which is reserved for a Pinot noir (PN) vineyard.  The backstory of this particular PN clone is great stuff.
Dating back to Roman Britain, a mere 2,000 years, the Wrotham (pronounced root-um) clone of PN was discovered growing in a churchyard in the village of Wrotham, Kent.  Said to be naturally disease-resistant, the leaves of the Wrotham clone apparently have a covering of fine white hairs on the upper surface of the leaf blade - I shall have to try and see this for myself next spring.  Dr. Peterson's website has more information on this most unusual of Vitis vinifera clones.  Good stuff.
Rejoice with something pink.
Sing it Maddy!

A little book of horrors.

I am always looking for good viticulture reference books and my brand new copy of Vitibook just happens to be a great one.  Written by Diego Barison et al., Vitibook was actually published last year, however, I only just learnt about it.  I had contacted Glenn McCourty, who is a Viticulture & Plant Science Advisor at the U.C. Davis Cooperative Extension for Lake and Mendocino counties (on the advice of wine columnist Dan Berger), to ask if he knew of any published data on Vitis clonal selections that are available to the grapegrower.  And yes, he did.
Vitibook is a little gem of a book out of Italy that is just perfect for a vino-geek like me.  The book is very thorough in its coverage of grapevine morphology and phenology and it includes interesting statistical data about grape-growing regions around the world.  The section on clones is informative and is exactly what I was looking for.  It is the horrifyingly graphic chapters on grapevine diseases and pests that really make this book worth owning.  Replete with full colour photographs that document all sorts of grape maladies and creepy-crawlies, it is a small wonder that anyone would ever decide to develop a vineyard at all.  Frightening.
Vitibook is a wonderful addition to my modest collection of all-things-grapey-reference books.

Afternoon in the Vineyards: 2014.

The 14th annual 'Afternoon in the Vineyards' was held today, so Vinomaker and I put on some sensible vineyard-boots and headed over to the Carneros American Viticultural Area.  The closest vineyard, on the list of six from which to choose, was that of Pine Ridge Vineyards - their Carneros Collines vineyard on Buhman Avenue.
Pine Ridge grow Chardonnay and Merlot at this location and both varietal wines were available for tasting, so we did (Vinomaker even went back for seconds).  It's a nice vineyard.  Viticultural experts who work for the Napa Valley Grapegrowers, a co-sponsor of the event, were on hand to answer any questions visitors may have had.  The bottom, level half of the vineyard had originally been planted to Merlot and had been grafted over to Chardonnay clones 76, 95 and 96 within the last 2 years (I would guess). 
The old Merlot trunks were quite old and gnarly.  There were lots of questions from the attendees about these not-so-normal looking grapevines; How does one go about attaching the bud?  And how does one end up with the two arms of a bi-lateral cordon?  It was fun to stand in the sun, with my 2 ounces of Merlot, and just listen to the conversations.  Vinomaker and I didn't stay for too long, after all, I had things to do in my own vineyard.  It's always a fun event.

It's not rocket science.

A friend, Sky King, brought this newly released cult wine (Sky King's words, not mine) over for Vinomaker and me to try last night.  The 2006 Rocket Science, from Caldwell Vineyard, had great colour extraction, a high alcohol content (14.9%), heavy mouth feel, not a lot of tannins, an underripe red plum fruitiness and a burst of vanilla on the finish. Yes, being a 2006 it is young, but I think you can take its youthfulness out of the equation: this wine just seemed a little out of balance to me. Thankfully, this is not John Caldwell's (famous in these parts for his suitcase clones) primary label, other Caldwell wines I have tasted have been far more enjoyable. The name, Rocket Science, I am assuming is a tongue-in-cheek attempt at saying that winemaking is NOT rocket science.  That's right, it's not.  But it can get awfully complicated.
Is Caldwell a cult wine?  I personally don't buy into the whole cult wine fad.  Last year I was fortunate enough to be able to partake in a blind tasting of wines commonly referred to as 'cult wines' - Bond, Harlan, Phelps, etc., all 2002 Cabernet Sauvignons.  My favourite was a David Arthur Elevation 1147.  I'm a bit of an 'emperors new clothes' type person, so I'm usually not easily influenced by the opinions of others. To me, the David Arthur was simply the best of the bunch because I was assessing it with my taste buds, nobody else's.
Rocket Science is great if you like a particular brand of humour paired with your wine.  Admittedly, it was a rather nice quaffing wine once it opened up, albeit a little young right now.  In the end, I was just left feeling sorry for the poor retailer who is trying to merchandise this wine, on it's side, in a bin.  The angled sides of this bottle would make it rocket right out onto the floor, whoosh!
To quote Colin McPhail of Larkmead Vineyards, "Less cult, more cultivation". With that being said, I'm launching myself out into the vineyard.
