New Machine Uses Density to Meet Grape Sorting Challenges

To ensure quality, many wineries engaged in grape sorting, and at the basic level, that sorting starts with labor – a scarce commodity in California at this time.A new option in the US market is the Tribaie Grape Sorter, made by the French company Amos Industrie and Staglin Family Vineyard, a high-end winery in Rutherford, Napa Valley was the first U.S. winery to buy and trial the Tribaie grape sorting machine on some of their fruit.Normally the first line of quality control is hand-sorting the clusters of grapes; that is, removing all visible leaves, debris, and obviously bad bunches before the grapes hit the crusher/destemmer. Used for millennia, this process is constrained by the shortage of labor, and even in premier grape-growing areas labor issues push more and more wineries to use machine harvesters.The winemakers at Staglin Family Vineyard were impressed by the Tribaie at a wine show in France and by some of the wineries that use it in Europe and decided to invest and try out in the machine. Company representative Gilles Deschamps was on hand for the trial of the new machine at Staglin during their Cabernet harvest.The Tribaie offered a commanding presence on the crush pad. Using density to sort grapes, the machine bathes grapes in an infinity pool of sugar water and grape juice, which the winemaker adjusts to her preferred brix level by concentrating or de-concentrating the sugar content in the water. Grapes not dense enough due to lack of appropriate ripeness, float to the top of the solution and are siphoned off.Optical sorters that employ high-speed cameras and image-processing software to quickly scan and sort destemmed grapes; eliminating grapes that are lacking in color and shape have received some criticism for removing good grapes inadvertently, and they struggle with white wine variety grapes. However, the Tribaie works equally for white and red grapes, as the machine uses density, not appearance, as a control.Staglin picks everything by hand and the grape clusters were first fed into a de-stemmer. Next, the destemmed grapes were then led into a five-channel feeder, dispersing grapes into the bath in an orderly and even arrangement. Grapes not meeting the specific density settings, floated to the top while those meeting the density setting or heavier than the density setting sank to the bottom. The grapes that floated and the grapes that sank are then collected separately. Winemakers may choose to ferment only one of the groups of grapes or, one group of grapes for their primary wines and the other group for their secondary wines.

The sugar bath responsible for the specific density should be checked approximately every two hours, and be recalibrated as needed. If stored separately after use, the sugar solution can be reused after refrigeration and cold settling.Each machine is made to order by Amos Industrie, who makes many types of winery and fruit harvesting equipment. They started with their first such machine seventeen years ago, and currently have 105 machines operating across Europe in countries like France, Spain, Italy, and Portugal.Asked if they were specifically targeting Napa and Sonoma Counties where the average price per bottle is far higher than anywhere else in the US, Deschamps replied that they are targeting, “anyone who wants top quality, reserve wines.”Taking hand-harvested or mechanically picked grapes equally, the Tribaie can eliminate labor expenses of sorting, while improving wine quality, which seems cost beneficial. However the overall price of the machine may prove prohibitive to wineries that produce wines at lower volume and price point, or are satisfied with their current product.The tribaie is a versatile machine that can adapt itself to the brix level winemakers are looking for, because you can control the density of the bath solution. The machine consists of two different models that range from processing 5 – 20 tons of fruit per hour.Offered in two sizes, Amos Industrie will be showcasing their larger Tribaie at the North Coast Wine Industry Expo, held at the Sonoma County Fairgrounds on November 30 this year. Although the first vintage of Staglin Family Vineyards wine won’t be available for a taste test, Gilles Deschamps will be on hand to discuss the machine with interested parties and will have wine samples from his clients in Europe on hand to show the difference between wines made from the A and B selections. He notes that a designated technician is already in place in the USA for the first Tribaie, and those to follow.Advertisement last_img read more

Projected Week 9 DraftKings ownership percentage, NFL DFS advice

first_imgMORE WEEK 9 DFS: Values | Stacks | Lineup BuilderNFL Week 9 DFS Ownership: Tight EndTravis Kelce ($6,600) has rewarded people for paying up enough this season that they’ll do it again, especially with how badly the more frugal plays bombed out last week. …  Greg Olsen ($4,700) should join plenty of Cam stacks as Carolina gets the Bucs bump.Austin Hooper ($3,800) saw high target volume heading into the Falcons bye, though he may still go contrarian with Atlanta playing an outdoor game. That tends to draw a Falcons fade. The receiver deals at the trade deadline pose some interesting questions in projecting ownership for Week 9 NFL DFS contests. Since it’s important to evaluate roster rates heading into daily fantasy football GPPs and tournaments, let’s mull over these developments as they relate to value for DraftKings lineup picks.Like every week, I’ll reference UFCollective projections in parsing the factors affecting how the DK crowd may approach players and pricing. Week 9 Rankings:Quarterback | Running Back | Wide Receiver | Tight End | D/ST | KickerNFL Week 9 DFS Ownership: QuarterbackCam Newton ($6,600) against the Bucs is locked in for QB chalk since, you know, the Bucs. … Drew Brees ($6,100) and Jared Goff ($6,000) should split a very popular ticket with that Vegas over-under in the Superdome hitting the 60s.The field will likely shy away from Deshaun Watson ($6,300) given his recent lack of rushing volume. Swinging on him as a contrarian requires a bet on health and competitive game flow, but it’s still feasible.WEEK 9 DFS CASH LINEUPS: Yahoo | FanDuel | DraftKingsNFL Week 9 DFS Ownership: Running BackTodd Gurley ($9,500) and Alvin Kamara ($7,300) should bring yet more chalk to New Orleans on Sunday afternoon, though UFCollective tabs Gurley as the fave to break 30 percent. … Kareem Hunt ($7,700) should also get plenty of run with the Browns written off as an crapshow this week and, thus, projected positive game script.Adrian Peterson ($6,000) nabs 25-plus touches when his team avoids getting routed and gets a modest uptick on his historical passing-game opportunity. However, his low receiving volume relative to the premium backs probably gets him faded to single-digit shares in GPPs, even with Chris Thompson out and AP coming off a week converting a red-zone receiving TD. WEEK 9 DFS GPP LINEUPS: Yahoo | FanDuel | DraftKingsNFL Week 9 DFS Ownership: Wide ReceiverThe WR trades aren’t factored into DK pricing, and this makes Courtland Sutton ($3,900) a prime candidate for cheap chalk. … Emmanuel Sanders ($6,400) rode in with the Broncos lead in air yards and still pull in more work during the first week without Demaryius Thomas ($4,500). This could spring Manny to medium ownership and a far lower rate for Thomas. Sammy Watkins ($4,900) comes off a smash week, and if Tyreek Hill’s injury holds him back, Watkins will be destined for chalk. An active Hill would likely cap Watkins short of chalk as heavy-favorite KC visits Cleveland. … Kenny Golladay ($5,500) and Marvin Jones ($5,300) don’t get the same juice from Golden Tate’s absence, as Minny’s feared D comes off a low-volume pass week against the Saints.last_img read more
