Happy first day of spring!

My vineyard is just starting to come to life.  The above champini will probably be the first to break bud, perhaps in 2 days.  You can already see the green leaf shapes pushing out of the red fuzzy scales.

I've been spraying dormant oil on a 2 week schedule, with 6 selected vines getting sprayed on a 1 week schedule.  It seems to be doing a good job of delaying bud burst.  Also, it seems to be differentially impacting buds such that there is a much wider spread in 'start times'.  Combined with my late pruning (no pruning done, yet), I think my chances of getting at least a few primary buds to survive the frost season (Feb 15 to April 15) is much, much better.

Based on the forecast, there is a fair chance of a freeze here on April 3 and 4th.   The forecast is for 43 and 44, but I'm often 10 degrees cooler.

Below is a record of low temps in my vineyard.  The temps come from Opossum Hollow, about 2 miles up the river.   I've spot checked my vineyard temps, and they match very well.  Out of 8 years, there was only 1 spring without a freeze between 3/29 and 4/15.  The chances this early bud will survive are low, but a lot of other buds will be fine.  Those late buds will be the ones that produce the next generation of grape seeds here.

Typical 1st week of March - temp 26F and falling


As I write, the temperature in the vineyard is 26 F and falling. Sleet was expected tonight, and arrived on schedule.

Last night I noticed a hole in the greenhouse roof.  I'm glad I check on the seedlings before going to bed.

searching for a 2 liter auto-vinification system

Tonight, I've continued my search for a system/equipment combo capable of turning 2 liters of grape juice into a representative bottle of wine.

from: Showstoppers From SIMEI and Enovitis

auto-vinification tank systems: automated cap management, temperature control and the handling of lees, seeds and pomace

Automated fermentation systems have a number of advantages over manual pump overs.
1.  labor savings,
2.  automated systems can deliver precise and repeatable regimens day and night
3. respond to tank temps, Brix level, carbon dioxide evolution rate, etc.
4. Cross-contamination among tanks is avoided, (line of sight guesses about pipe connections is dangerous)

DEFRANCESCHI FERMENTERS

punchdown-vs-pumpover
"Pumpovers can extract higher amounts of tannin in a wine depending on the frequency and force. Some pump over systems are basically wine sprinklers, offering a gentler extraction and some aggressively stir up the fermentation tank. For larger fermentation tanks in commercial operations, much needed oxygen comes through a pumpover device.

Punch downs, on the other hand, are a very delicate way of stirring a wine. They keep skins from getting too extracted and little to no amount of added oxygen in the fermentation. Punch downs are typically done by hand and are more popular with non-interventionist winemaking."

An alternative view of the Loire salons:

"Everything is getting bigger. La Dive Bouteille had a spacious new home in the troglodite caves of Caves Ackerman; Salon Les Penitantes covered two floors. The dinner after Les Vins Anonymes - arguably the smallest of the tastings - exerted such a gravitational social pull that I wondered how all the attendees would ever fit in the Collegiale Saint-Martin. (I hadn't been tempted to go to this year's dinner, because I'd heard last year's event had all the organisation of the Katrina response. But perhaps I'll go next year.)"

...

" if we agree that natural winemaking favors the inherently communal concept of terroir, rather than the more individualist, auteur-focused winemaker culture that obtains in most modernised New World regions, then we should admit that European natural wine buyers, and in turn their clientele, can learn very little from the isolated examples of one winemaker or one importer."

NY Times take on Loire natural wines

from: In France, Pesticides Get in Way of Natural Wines (NY Times) 

The first of the weekend tastings, Renaissance, in Angers on Jan. 31 and Feb. 1, brought together producers who make organic, pesticide-free, but not necessarily sulfite-free, wines.  ...



If the Renaissance salon was the most established of the nonpesticide tastings, Les Anonymes, a short distance away, was the most radical and uncompromising...


In Saumur, about 26 miles away, a much larger group of nearly 200 winemakers from 15 countries displayed its wares in a warren of cold, damp troglodyte caves. Called La Dive Bouteille, it has become the world’s largest annual natural wine exposition, with 3,000 visitors this year....

The article lists the three largest pesticide users as the United States, Japan and France, and suggests restricting pesticide use is gaining popularity.  Despite this:

"The pesticide and big-agriculture lobbies are strong, resisting any initiative that could affect farm yields, so there is little political will to take risks. In late January, the French agriculture minister, Stéphane Le Foll, announced that a government pledge to cut pesticide use in half by 2018 would be delayed until 2025..."

Why did I start breeding grapes?

There are many mustang grapes on my property.  They make lots of grapes each year, but they taste like chili peppers.

In 2005, I decided to grow some interesting grapes I found in a local nursery.  One was called Himrod, another was Thompson seedless.

My neighbors said I couldn't grow grapes on a Texas river bank, especially the river I lived on.  I needed to be up on a hilltop, where frost was rare.

They were right about the frost.  I had late frosts every year.  After a late frost, I would want to cry.  Almost all my vines would lose their flowers.  No matter how good I got at keeping them healthy the rest of the year, there would be little or no fruit.

After losing the 2009 crop to a late frost, I came across some vines flowering on a river bank 30 miles from my home.   I was on my way to visit a place called 'Sand Hill', but to get there we crossed a number of creeks.  One had these magnificent flowering vines.

When I tasted the fruit that fall, it was small, but very good. The obvious solution was breeding.

Why cry?  As a breeder, the late frosts are just helping me select good vines.
