Sweetness on dry wine
Make seem lose fruit and unpleasantly acidic
Umami: High Risk
Pair with more fruity than tannic; can be balanced by acid or salt, but not alter character of dish
Sweet Wine Temp
6-8 (43-47)
Roostock uses:
Soil salinity, drought, nematodes, vigor
Chardonnay temps
cool
more favorable sites or moderate
warm and hot
very hot
Cabernet Regions
Chile (colchagua)
Water Hazards
Prolonged Drought: h2o stress, may stop photosynthesis, leaves wilt, grapes fail to ripen, can weaken or kill
Too Much h2o during Growing Season: excessive vegetative growth; divert glucose, increase risk of shading; impede ripening
Excess Rainfall toward end: damp rot, dilute, swell, burst
Summer Hail: damage grapes and wine; netting, seeding clouds
Continental Temperatures
Short summers with large drop in autumn
Cool: spring frost, disrupt ripening, flowering fruitset
Moderate
Warm and Hot: may need irrigation as summers very dry
Maritime Spring and Summer Rain
Significant risk to flowering,, fruitset, health of grapes at harvest
Mediterranean
Summers tend to be warm and dry
Mediterranean, coastal cali, chile, SE Australia, Cape Winelands
Extra warmth compared to Maritime: fuller body, riper tannin, high alcohol, lower acid
Summer Pruning
Trim canopy to restrict vegetative growth and direct sugar production to grapes rather than shoots or leaves
Downey Mildew
Warm, humid. Attack green parts.
Leaves: ripening
Grapes: yield
Powdery Mildew
warm, shady, attack green
damage bud development and shoots
berries, split, dilute flavors mold bitter taint
Grey Rot
Mainly immature berries; taint, lose color, decrease yields
Fanleaf and Leafroll
Spread by cuttings and nematodes
Ideal Harvest
ideal balance between physiological and sugar ripeness fro variety, style and quality
Too Much O2
Extreme cases acetic acid bacteria to vinegar
decrease intensity and flavor, lack fruit, browning, unfit to sell.
Altering Sugar and Alcohol
Must Enrichment
Reverse Osmosis, Vacuum Distillation
Tartaric acid solubility
Less soluble in alcohol than grape juice
Tartaric Acid Processing
Filter
Remove Colloids via fining
Oxygen Stability
So2 in line with aging
Anaerobic bottling
Flush
Goals of Closures
Protect from harm until consumed
Allow for maturation if intended; happens with inert closures
