20.3 Producing Inexpensive, High-Volume Red Wine Flashcards
Inexpensive Red Wine Production
CAP MANAGEMENT
CHOICE (2)?
REASON (3)?
INFLUENCE ON STYLE / QUALITY / PRICE (3)?
CHOICE: 1) Standard mechanized pump-over and/or punch down.
2) Option of rotary fermenter.
REASON: 1) Extraction of desired color/aroma compounds/tannins.
2) Rack and return would involve availability of additional empty vessels.
3) Roto-fermenters = efficient extraction.
INFLUENCE: 1) Fruity wine w/ desire color intensity + medium tannins.
2) Roto-fermenters = more intense color/tannin/flavor, best for darker varieties (e.g. Cab Sauv)
3) Roto-fermenters = $$$ (can be recovered via high volume + quick throughput)

HARVEST
CHOICE?
REASON (2)?
INFLUENCE ON STYLE / QUALITY / PRICE?
CHOICE: Machine Harvest
REASON: 1) Quicker / Cheaper / Allows cooler night harvesting.
2) Fruit already removed from stems = destemming not needed.
INFLUENCE: Cheaper option for larger vineyards = lower price.

MALOLACTIC CONVERSION
CHOICE?
REASON?
INFLUENCE ON STYLE / QUALITY / PRICE?
CHOICE: Will occur naturally, but can be hastened by adding lactic acid bacteria so it occurs simultaneously w/alcoholic fermentation.
REASON: Speeds up process, freeing up tank space, allows wine to be sold sooner.
INFLUENCE: Smoother, softer style + microbial stability.

CRUSHED FRUIT FERMENTATION
CHOICE?
REASON (2)?
INFLUENCE ON STYLE / QUALITY / PRICE?
CHOICE: Grapes crushed to release juice + begin fermentation. Cold maceration unlikely.
REASON: 1) Facilitates beginning of fermentation + color / flavor / tannin / aroma extraction.
2) Cold maceration = slower process.
INFLUENCE: Adequate depth of color / flavor / tannin level.

GRAPE RECEPTION
CHOICE?
REASON?
INFLUENCE ON STYLE / QUALITY / PRICE?
CHOICE: 1) Limited sorting (MOG only.)
REASON: 1) Saves $$$ on time, labor, equipment and lowering yield.
INFLUENCE: 1) Keeps $$$ low = price of wine low.

PRESSING
CHOICE?
REASON (2)?
INFLUENCE ON STYLE / QUALITY / PRICE (2)?
CHOICE: Pneumatic Press either during or after ferementation.
REASON: 1) Large loads of grapes
2) Pressing during fermentation lessens extraction of tannin.
INFLUENCE: 1) Larger loads = less processing time = less $$$.
2) Lower tannins = smoother wine, appropriate for style desired.

TRANSPORTATION TO WINERY
CHOICES (2)?
REASON (2)?
INFLUENCE ON STYLE / QUALITY / PRICE (2)?
CHOICE: 1) At night / early morning if viable (otherwise daytime is fine.)
2) addition of SO2.
REASON: 1) Cooler conditions for grapes
2) SO2 protection from microbial spoilage + oxidation.
INFLUENCE: 1) Limits effects of oxidation and microbial spoilage = better quality, retains aromatic style. Warmer = higher risk of oxidation + microbial spoilage.
2) SO2 retains quality.

EXTRACTION USING HEAT
CHOICE (2)?
REASON?
INFLUENCE ON STYLE / QUALITY / PRICE (3)?
CHOICE: 1) Flash détente
2) Thermovinification
REASON: Rapid extraction of color w/low extraction of tannins = faster, no need for extended maceration on skins.
INFLUENCE: 1) Fruity, low tannin wines suitable for early sale/consumption.
2) Thermovinification = added cost (but money is saved via less time/tank space)
3) Flash détente = substantial initial investment (but money is recovered by large volume production + time/tanks space saved.)

ADJUSTMENTS
CHOICE?
REASON?
INFLUENCE ON STYLE / QUALITY / PRICE?
CHOICE: Acidification / Deacidification / Chaptalization dones as necessary.
REASON: Depends on ripeness of grapes.
INFLUENCE: Enhances balance of wine = higher quality. Might add slight cost.

VESSEL + TEMPERATURE DURING FERMENTATION
CHOICE (2)?
REASON (2)?
INFLUENCE ON STYLE / QUALITY / PRICE (2)?
CHOICE: Cool - Mod. Temps (17-25 C / 63-77 F)
Stainless Steel.
REASON: Warm enough to extract flavor+tannins, but retains aromatic compounds.
Steel tanks allow for temperature control + ease of cleaning
INFLUENCE: Creates + retains aromatic, fruity style.
After initial investment in computerized, temp-controlled tanks, costs are recovered through high volume + fast throughput.

YEAST FOR ALCOHOLIC FERMENTATION
CHOICE?
REASON?
INFLUENCE ON STYLE / QUALITY / PRICE?
CHOICE: Cultured Yeast.
REASON: Reliable, specific strains can increase aroma release+creation.
INFLUENCE: Creates + retains aromatic, fruity style. Less risk of off-flavors which would lower quality.
Inexpensive Red Wine Production
CARBONIC / SEMI-CARBONIC MACERATION
CHOICE?
REASON?
INFLUENCE ON STYLE / QUALITY / PRICE (2)?
CHOICE: Promoting intracellular fermentation.
REASON: To produce fruity, low tannin wine.
INFLUENCE: 1) Distinctive kirsch / cinnamon / bubblegum / banana flavors.
2) Generally used for early-release+consumption wines.
Inexpensive Red Wine Production
BLENDING
CHOICE (2)?
REASON?
INFLUENCE ON STYLE / QUALITY / PRICE?
CHOICE: 1) Blending might occur to maximize volume and maintain continuity of style.
2) Free run wine might be blended w/press fractions.
REASON: More volume of acceptable quality level.
INFLUENCE: Acceptable quality. More wine = More $$$
Inexpensive Red Wine Production
POST-FERMENTATION MACERATION
CHOICE?
REASON (2)?
INFLUENCE ON STYLE / QUALITY / PRICE (2)?
CHOICE: Usually not carried out (at most 3-5 days.)
REASON: 1) Takes up time / tank space.
2) If done, extraction is increased.
INFLUENCE: 1) Fruity wine w/desired level of color + med. tannins.
2) Additional maceration = $$$ for monitoring + usage of tanks that may be needed for other wine.

FINISHING
CHOICES (3)?
REASON (3)?
INFLUENCE ON STYLE / QUALITY / PRICE (3)?
CHOICE: 1) Tartrate Stabalization (contact process, metatartaric acid or CMC.)
2) Fining
3) Sterile Fertilization
REASON: 1) Consumers will not accept tartrate crystals. CMC + metatartartic acid = cheaper than cold stabalization.
2) Ensures wine’s clarity + brightness.
3) Avoids risk of faults developing in bottle.
INFLUENCE: 1) Quicker release of wine = less $$$ for storage = cheaper wine + faster return.
2) Maintains style + quality
3) Extends shelf-life.
