This year’s wine grape harvest is in high gear, and growers say this season is returning to normal after a couple of drought-impacted vintages. or leaf removal within the canopy to increase air flow and filter sunlight and using drip irrigation and sprin- klers during major heat spikes, she said. Growers have been watching their vineyards closely and managing them by hand to ensure quality and avoid fruit damage, she said. “No growing season is ever the same and farmers are experts at quickly and thoughtfully responding to varying weather conditions,” she said. A reprieve from the hot weath- er was expected this week, as Napa Valley temperatures were slated to top out in the low 80s this weekend, according to the National Weather Service. Long-range forecasts show valley highs averaging in the low to mid-80s for the remainder of Sep- tember. Parts of the San Francisco Bay area had of rain on Sept. 11. Growers throughout California are in the midst of harvesting an an- ticipated 4 million ton wine grape crop, down slightly from last year’s production of 4.03 million tons, ac- cording to the National Agricultural Statistics Service. The industry is getting back to normal after drought-related water shortages led to lighter crops in 2014 and 2015. Wine represents 60 per- cent of the state’s total grape crop. While the first grapes for Napa Valley sparkling wine were picked Aug. 7, fog and cooler daytime tem- peratures slowed the pace of harvest in early August, but grapes start- ed coming in at a steady pace once warmer days arrived, the Napa Val- ley Grapegrowers reported. FRESNO, Calif. — Raisin producers who were already ex- pecting a smaller crop are assess- ing the damage from stray show- ers that spritzed grapes that were drying on the ground. Thunderstorms that passed over the San Joaquin Valley on Sept. 4 dumped as much as a half- inch of rain in some vineyards, said Kalem Barserian, the Raisin Bargaining Association’s chief ex- ecutive officer. Rain can make raisins drying on paper trays dirty or moldy. It could take several weeks before growers know the extent to which their crop was damaged, industry officials said. “The biggest thing when it rains is, ‘Can I get them dry?’ and the key to that is to get good weather immediately following,” said Rick Stark, grower relations manager for Sun-Maid Growers of California. Temperatures in the valley reached triple-digits on Sept. 5 with a slight breeze, he said. “You couldn’t ask for better than that,” Stark said. “We’ve gotten good weather since that. There’s actually people out boxing and there are still people picking. They’re doing the same thing they were doing before the rain. It just took a couple of days to get ev- erything dried back out to where it was.” The setback comes as farms faced insurance policy-imposed at North Idaho Fair Submitted by Sharla Wilson, Kootenai Extension Educator – 4-H Youth Development deadlines of Sept. 20 to finish hand-picking grapes for raisins and Sept. 25 to finish continu- ous-tray harvests by machine, Stark said. All the raisins have to be out of the field by Oct. 20, he said. Growers are expected to pro- duce a 1.45 million-ton raisin crop in 2017, down from 1.54 million fresh-weight tons last year, ac- cording to the National Agricul- tural Statistics Service. But they could have difficulty even meeting the NASS estimate. Barserian said it’s the shortest crop he’s seen since 1998, another big rain year. That year, California produced only 248,000 dry tons of raisins while it averaged 336,000 dry tons. About 4 to 4.5 pounds of fresh grapes dry into a pound of raisins, according to the Universi- ty of California-Davis. “That year we had 20 inches of rain and this year we had 18 inches,” he said. “The vine takes a rest when there’s a lot of water. … Typically your bunch count is 39 bunches per vine. This year it’s 27.” The shorter crop could help the industry rebound from a price slide. Last year, prices bottomed out at $1,100 per ton, down from $1,600 the previous year, and the cost of production is about $1,400 per ton for a standard vineyard, Barserian said. While prices for this season have yet to be negotiated, some packers are already offering from $1,500 a ton to as much as $1,700 on a contract basis, he said.

NAPA, Calif. — The latest in a string of heat waves this summer has complicated a wine grape harvest that vintners had considered a post- drought return to normal. Triple-digit afternoon tempera- tures in California’s prime wine-pro- ducing regions early this month left vintners scrambling to take protec- tive measures to keep grapes from shriveling on the vines before crews could pick them. In the Napa Valley, where tem- peratures reached as high as 107 de- grees on Sept. 2, growers say fruit quality remains high because of win- ter rainfall and vineyard practices they employed during the growing season. Heavy winter rains replenished reservoirs and brought soil moisture levels back to full capacity, said Hei- di Soldinger, the Napa Valley Grape- growers’ marketing and communica- tions manager. “Grapevines draw from these stores of moisture throughout the warmest summer months,” Soldinger said in an email. “In this way, stable soil moisture levels act as a natural heat buffer. Also, to date, air humid- ity levels remain high, even on the hottest days. The damp air, as with soil moisture, acts as a cooling ele- ment in the heat.” Further, certain vineyard man- agement practices helped growers protect their crop, Soldinger said. Techniques have included tunneling 11 Garret Booth, 10, shows his hog at the North Idaho State Fair in Coeur d’Alene. The Kootenai/Shoshone 4-H Program had a strong presence during the North Idaho State Fair in Coeur d’ Alene Idaho August 23-27. We had over 1,700 4-H entries from our 705 enrolled members who were supported by over 230 adult volunteers this year. The 4-H projects entries ranged from the traditional sewing, cooking and livestock to robotics, aerospace and everything in between. One of the highlights was the first annual Small Animal Market sale where we sold a combined total of 21 pens of poultry and rabbits bringing in over $7,000 for those members. Even more notable, at our large animal sale we had a sale total of over $520,000. This year we sold 183 hogs, 51 steers, 43 market lambs and 17 meat goats. committed to donating the proceeds of his market lamb to Garret Booth’s family to help with medical expenses. Additional highlights from our sale also included the community support of Garret Booth and his family. Garret, age 10, battled cancer this year but remained determined to continue his involvement in the 4-H program. He had the reserve champion market hog and during the sale his hog was not sold once but twice with those additional proceeds going to help him and his family. To his surprise when he picked up his lamb this spring from the Hansons he was also given all of the feed that he would need to finish his project. Staying true to his word, he committed his entire market lamb check to the Booth family. We also had a market lamb member, Cyrus Vore, who had received a lamb through a Pay It Forward essay program in conjunction with Hanson Livestock. In his winning essay he It is moments like this that you truly get to see the heart of a community and we are reassured that there are youth leaders in the next generation that are headed in the right direction. Our wonderful community supporters raised the bids on both Garret’s Hog and Cyrus’s lamb to over $20 a pound. 38-1/HOU
