  • Weak shoots and irregular ripening
    A built in survival technique for the vines, not have all fruit ripen at same time
    Seed ripeness and propagation of the vines – wide window of opportunity for birds, etc.
    Role of verasion thinning
    @ 1.5 Brix per week
    2 week wide window of flowering  to minimum of 3 Brix wide window
    To get average Brix right = field sample
    Must have some very over-ripe fruit
    Field sample is a mixture of under and over-ripe fruit
    Effects of unripe fruit in the mix of ripe fruit
    Action is to remove the unripe = green fruit in reds
    At about 85% coloring, drop out the green fruit
    If crop is large, do your crop thinning at this time
    Assumes the vine is not grossly overcropped
    All weak shoot fruit is off already – get it early when less time critical
    This work is time-critical, lot of acres to cover in few days
    Do a variability study

    • 1. Winegrowing @ Vilafonté November 22, 2011 @ Vilafonté Phil Freese & Edward Pietersen
    • 2. Today: “Today: “Beginning With The End In MindBeginning With The End In Mind”” • Defining ‘target’ wine characteristics and attributes – “Absolute” vs. “Relative” • Know the site: Soils, Climate, Plant materials • Know the ‘tools’ available to drive the outcome for the wines • Design vineyard and wine growing to meet the wine objectives using the best ‘tools’ • Seasonal wine growing = “The Game Plan” – Management is sensitive to • “The Game Plan” & overall wine objectives  above • The season  The “Plan” becomes Reality of season
    • 3.  Training is VSP  Vine spacing (1.2 x 1.6 m) = (4.0 x 5.25 feet)  5,200 vines/ha = 2,112 vines/acre

    • 6. Key Wine Growing Issues for VilafonteKey Wine Growing Issues for Vilafonte Soils “Old” soils – highly weathered Sub-surface drainage installed prior to planting row orientation to facilitate drainage “Vilafontes” is one of the soil types  Vilafonté
    • 7. Managing for wine characters and style:Managing for wine characters and style: Training and pruning to set shoot number and position – fruit display Water management – time & amount-stress – Build ‘sufficient’ canopy Leaf Water Potential (LWP) pressure bomb Drainage Crop control & Managing for uniformity of fruit ripening  Low yields per vine and good yields per hectare 7 tons/Ha = 1.4 Kg/vine (3.1 pounds per vine)  Intensity of character  Severe thinning fruit to ‘capacity’ of the shoots  Severe veraison thinning – achieve uniformly ripe fruit
    • 8. Key Wine Growing Issues for VilafonteKey Wine Growing Issues for Vilafonte Climate “Mediterranean” Winter rainfall area - about 25 - 30 inches (April – September) Low frost potential in the spring “Mild” summers Warm days and nights Higher relative humidity vs. California – less vine stress extremes Somewhat more regular ripening weather (more shallow diurnal temperature changes) Long post-harvest time for vine-ripeness Regular phenology Approximately 105 – 110 days, bloom to harvest
    • 9. G. Jones (2006)
    • 10. Grape Vine Phenology Dates And Data:Grape Vine Phenology Dates And Data: Some Practical Uses Within The Growing season:Some Practical Uses Within The Growing season: • Phenology is your ‘timeline’ for the growing season – Budburst to flowering is a ‘squishy’ number (heat limiting in spring) – Other stages are very reproducible (heat saturated – in most “New World” areas) • Timing between events is very regular season-to-season for a given site, variety and vineyard block • Timing within an event is a measure of variability – Number of elapsed days from 5% to 95% • Net – you can project timing of vine events from your phenology data: – Flowering dates and fungicide sprays – Cutoff date for last sulfur application to avoid residue on fruit – Water management – choose a stress level (severity) and (time) to hit this level – When you need to do veraison thinning – Harvest timing – French plan their summer vacations!

    • 18. The Vine: Uneven Fruit RipeningThe Vine: Uneven Fruit Ripening • Non-uniform ripening of fruit is probably a large positive benefit for better evolutionary competition – More chances to have animals feed on some of the berries as they come ripe: • Better chance of ripening in the migration time of birds – Better chance of surviving different climate conditions • Non-uniform ripening is not positive for winemaking objectives! – Lack of ‘focus’ of aroma and flavor – mixed berry characters • Variations within: – Vineyard – area to area – Vine – bunch to bunch – Cluster – berry to berry
    • 19. Normalized Difference Vegetation Index = NDVINormalized Difference Vegetation Index = NDVI (Spatial Variation of Vegetative Index)(Spatial Variation of Vegetative Index)
