2009 Vineyard Log: The Importance of Good Records

Good record keeping is part of being a good steward of the land and a good winemaker. Keeping records is also a requirement to achieve "sustainable vineyard" designation. I've decided to post records of significant vineyard events & milestones under this journal headline, returning periodically to update. (I keep similar records of wine vintages as well.) Alas, no life and death stories today; just dreary facts. I am reminded of my friend Dr. Hugh Straley of Seattle who once observed, " When marathon runners get together they discuss their bowl movements." When I see my vineyard buddies this week I'll say, "I'm going through veraison." (I describe veraison as the grape's version of menopause as they make that transition from young, hard, green-pea to mature, luscious nectar, with heat flashes to boot.) To which the other grower asks, "What are the brix?" The Tempranillo (which means "early" in Spanish) are about 95% through veraison today, and yes I'll go out and measure the brix after I finish this post, and finish paying the bills (yes, there is that).... A few hours later.... The brix are at 15 and just for fun here's a little video showing how I picked the berries and measured the sugar.

2009 Vineyard Log

Last water in 2008 (mid-Nov., 2008)

Good rain storms November, December '08

Jan 30th started pruning in earnest, finishing February 14th (mostly)

Feb 21 - 22 (last major rain) Finished all pruning. Finished rain. Total season rainfall less than normal after getting out to a great start, about 8 inches.

Feb. 28 - March 8: Sprayed lime sulphur and oil


Planted about 40 Tempranillo Vines. (About 30 of these were a mistake and will be transplanted in winter.)

Bud Break: March 21. Lower part of vineyard (Petit Sirah), first bud break. Also, lower part of Petite Sirah on less vigorous root stock are netted early July. (Much mildew damage there).

April 17: Admire Treatment First Irrigation. Glassy wing sharpshooters appear in early April. Also, in July after setting yellow traps we catch 5 sharpshooters in one week. In August, the sharpshooters are gathering around the two rows of Tempranillo vines which have found their own source of water putting out green shoots. Cannot add Admire -- too close to harvest. This could be a problem.

2nd Irrigation two weeks later. (in hindsight, this one unnecessary)

May Water Usage: 26 HCF, 53% decrease from May 08 (May weather unseasonable cool, foggy, cloudy.) Vigorous growth throughout vineyard --especially lower Tempranillo and Petit Sirah on 5C rootstock--and should be able to cut back irrigation even more next year.

Planted 18 "potted" Aglianico vines end of May to fill in gaps.

Powdery mildew developed in late May (should have been spraying. Must implement spray program next year.) Treated with 10 pounds wettable sulphur and 2.5 lbs. Kaligreen, spraying June 10 - June 17 with backpack sprayer. Sunrise Vineyards management sprays with Rubigan on June 26th (whole vineyard in less than two hours).

June--Petiole analysis of Zinfandel block. Results show nitrogen deficiency, which can be remedied by composting. (Will order compost in fall for nutrition and erosion control.)

June Water Usage: 46 HCF (15% under water rationing allotment of 54 HCF).

July 19: Tempranillo veraison, 15 brix. (Picture at top shows the berries.) Zinfandel veraison beginning. Petit Sirah, heavily damaged by mildew, seems mostly a lost cause. Many Petit Sirah bunches "tight"--need to address. Aglianico -- just a few grapes turning. Aglianico crop is light, and we may decide not to pick. Grenache grapes still green; lost 1/2 to mildew. Promising harvest this year is Tempranillo and Zinfandel.

July Water Usage (7/6 - 8/5): 42 HCF (Allocation was 63 HCF). Except for one week of "hot weather" the week of July 18th, weather has been unseasonable cool.

August 1st: Tempranillo at 19 brix (100+ berry sample); taste is still tart. Will we be harvesting in 3 weeks? Petit Sirah lower block is already ready, but since block is small, holding back. Two lower rows of Tempranillo have found a water source, putting out green shoots. (Not good.) Must cut irrigation to them next year. Birds are finding holes in nets and penetrating, causing damage. Bees have arrived. Irrigated 1.5 hours (2 gallon/hr) this week. (Just one hour last week.) Zinfandel at 70% veraison. Grenache at 50% veraison. Aglianico still mostly green. Will drop most of the fruit. The Lord giveth and the Lord taketh away. Blessed be the name of the Lord.

August 7th: Zinfandel finishes veraison. Aglianico veraison beginning.

August 14: Tempranillo at 22 brix (100+ berry sample with hydrometer); pH=3.63; acid= .787 Zinfandel block at 19 brix; pH=2.98; acid = 1.54 Caught and released 5 birds today that had penetrated the nets. Grenache veraison complete. Last, light watering of Tempranillo (one hour) August 16th. Cool for 6 days, not much ripening.

August 26 (Weds): Tempranillo at 24 brix. pH= 3.75 acid (TA) = .7 Acid test done with Accuvin quick test, so accuracy is questionable. I also question accuracy of pH meter. (Will need to recalibrate.) Temperatures have warmed up since Sunday into the mid-80s, reaching 90+ today. No water last weekend. Grapes are ripening quickly now. Many (but not all) of the grapes damaged by birds have become sweet raisins. This may add "jam" characteristics to the wine and raise sugars.
Last week in August heat wave. Temperatures climbed above 90, close to 100 degrees. Zinfandel grapes dehydrating and at 26 brix on Saturday. Watered for one hour on Saturday to try and bring down the sugars. Mad rush to harvest the Tempranillio & Zinfandel last Sunday in August. (One container 1/2 full of Zin grapes left in vineyard ... must thoroughly check next year, and remind friends/pickers to bring grapes to the center of the vineyard, dumped ton larger containers, which can be easily transported downhill.) Tempranillo come in at 25 brix. Zinfandel come in at 27 brix and cold soak to 28 brix the next day. pH's of Zinfandel & Tempranillio are high. May need to water more next year during August to prevent such rapid ripening, but we'll see. The new wines made from these groups are fruit forward, and taste surprising good for new vines. About 1,100 pounds of Tempranillo, 500 lbs. Zinfandel, 100 lbs. Aglianico are harvested that Sunday. Mid-week, we harvest the Petit Sirah (about 400 lbs.) and the next Saturday (Sept. 5th) the Grenache. Full account of the wines (including brix, TA and pH is kept in the 2009 vintage log.) Some remaining Aglianico grapes/raisins used to raise sugar of Ramona Brunello grapes and Valley Center Petit Sirah grapes.
September watering: heavy watering after harvest. Seems to have been much stress on some of the vines, because of heat wave. Will need to see how they recover. Removed emitters from over vigorous vines near leach fields; and gave .5 gallon emitters to some other vines near leach field.
Sharpshooters in lower part of vineyard (Tempranillo mostly, some Petit Sirah vines) in August concentrated on over-vigorous vines. This is serious. Not sure yet of damage caused and extent of Pierce's disease infection. (Until now, it seems we've lost about 3 vines to PD.)
November 1, 2009 - Last deep watering. Water usage for October, including Nov. 1st watering was 35 HCF. Bill for October watering is $135.82 (Bill for September watering is )$173.62.

Education: Took Pete Anderson's course at Mira Costa Community College on Vineyard Management. Attended sustainability seminar put on by California Winegrower's Institute and am completing self-assessment.

More later.
