Study Notes
Fermented Alcoholic Beverages
- Fermentation is anaerobic respiration by yeasts, breaking down sugars into alcohol (ethanol) and carbon dioxide.
- Yeast fermentation is used in bread-making and alcoholic beverage production.
Wine
- Wine is made from fermented grape juice.
- Most wine grapes are Vitis vinifera, originating in the eastern Mediterranean.
- Some cold-hardy varieties are hybrid crosses with North American grape species.
- Grapes take 5 years to mature, with older vines producing better wine.
- Ancient Romans trained grape vines on branches. Modern viticulture involves pruning.
- Grape varieties are vegetatively propagated (clonally) for genetic uniformity.
- Approximately 50 grape varieties are used, but only 10 are considered classic.
- Grapes face pests like fungal mildews and phylloxera (an aphid).
- European grape varieties are grafted onto North American rootstock to combat phylloxera.
White Wine
- Grapes are destemmed and crushed.
- Crushed grapes are pressed horizontally to extract juice.
- Skins are discarded.
- Must is pumped into a fermentation vat.
Red Wine
-
Grapes are destemmed and crushed (only red grapes).
-
Crushed grapes and skins are pumped into a vat.
-
Fermentation lasts ~2 weeks; all sugars are metabolized.
-
Free-run wine is extracted, followed by a pressing of skins for additional liquid.
-
Additional liquid (high in tannins) is added to free-run wine.
-
Wines are filtered to remove yeast. Bottled, corked, and aged.
-
Aging is important, especially for red wines.
Global Wine Industry
- Over 25 million acres of vineyards worldwide.
- Major producers include France, Italy, US (California), Australia, South Africa, and South America (Chile/Argentina).
- Wine grapes grown in warmer regions like Okanagan, Canada.
Wine Production Countries: France
- Pioneered quality control and labeling laws.
- Classification system based on location and reputation.
- Classifications include: Vin de Table, Vin de Pays, VDQS, and AOC (highly supervised).
- AOC wines are further classified by geographical location, vineyard, or single vineyards (most expensive).
- Famous regions: Burgundy, Bordeaux, Champagne.
Wine Production Countries: Italy
- Wine laws introduced in 1963, with 3 classifications.
- Classifications include Vino de Tavola, DOC, and DOCG.
- DOCG wines are highly regarded and exported.
- Examples: Barolo, Barbaresco, Vino Nobile di Montepulciano, Chianti Classico.
Wine Production Countries: Germany
- Most German wines are white, often sweet, and lower in alcohol (9-11%).
- Wine production restricted to warmer southwest regions.
- Wine Law (1971) based on grape quality (sugar content).
- Classifications include: Deutscher Tafelwein, Qualitätswein bestimmter Anbaugebiete (QbA), Qualitätswein mit Prädikat (QmP).
- QmP wines further classified based on maturity (sweetness): Kabinett, Spätlese, Auslese, Beerenauslese, Trockenbeerenauslese.
Wine Production Countries: Spain
- Third largest wine-producing country in Europe.
- Gran Reserva (red: 2 years cask, 3 years bottle; white/rosé: 4 years total, including half in cask)
- Sherry (Jerez): southern Spain, blends of palomino grapes aged in the solera system.
Wine Production Countries: Portugal
- Major producer of fortified wine, port, produced near the Duoro River.
- Port made by adding brandy to partially fermented red wine.
- Aged in barrels (up to 50 years).
Beer
- Beer produced from starch sources (barley malt is principal).
- Other ingredients include sugar, hops, and beer yeast.
- Production steps:
- Germinate malt barley seeds.
- Mash with carbohydrate addition and hot water.
- Boil wort with hops.
- Cool wort and add beer yeast for fermentation.
- Two types of brewer's yeast: top ferments, bottom ferments.
- Beer filtered and aged; commonly artificially carbonated.
Distillation
- Increases alcohol concentration beyond fermentation limits.
- Distillation involves boiling fermented mash, capturing alcohol vapor.
Distilled Alcoholic Products
- Brandy: Distilled wine, aged in wood.
- Whiskey: Aged distillates of grain ferments, aged in white oak barrels (Scotch, Irish, Bourbon, Rye).
- Vodka: Distilled wheat-barley malt mash.
- Rum: Fermented and distilled sugar cane juice or molasses (Puerto Rican, Jamaican).
- Tequila: Fermented agave plant stems, traditionally involves an agave "worm".
- Liqueurs: Distilled beverages flavored with herbs, spices, fruit, and sugar (e.g., bénédictine, chartreuse, Jägermeister, sambuca, amaretto, frangelico).
