Udemy Lecture Notes

Throughout the semester as I watched Boyer's Udemy lectures, I kept some notes that I thought were helpful and can use as a reference later on/for people who might want to check out my blog and actually be able to learn something! 

Udemy: Dry vs. Sweet
-       How long you let the wine ferment and how much residual sugar is in the grape determines alcohol level; the longer the grape stays on the vine, the more sugar it will have
-       Sweetness gives suppleness
-       White wines are lighter, fruiter, and have a bit of residual sugar (best for beginners) and lower in alcohol; 10-12 % alcohol
-       Red wines are drier, have no sugar, higher in alcohol 13-15%
-       Fermentation is when yeast is allowed to eat the sugar in the grape juice, producing CO2 and alcohol; yeast eats all sugar until there is no more or winemaker kills yeast with chemical or heat
o   A dry wine means all the sugar has been eaten and left with only aromas and flavors
o   Dry wines are therefore more alcoholic
-       Pink wines from America are sweet, pink wines from France are dry
-       Amount of sugar determines German labeling
o   Kabinett – average ripeness
o   Wehlener Spatlese – grapes left on vine longer
o   Graacher Auslese – grapes left on longest (more sugar, more alcohol)
-       Sparkling wines are based on sweetness level
o   Brut – fermented out, totally dry
o   Extra brut
o   Demi-sec – semi-sweet, little residual sugar
o   Dolce/sweet

Udemy: Old World vs. New World
-       New World STYLE vs. Old World STYLE
-       Old World (Europe, France, Italy, Spain, Portugal, Germany)
o   Is labeled by where it’s from and has name of region on label due to history and how they make wine, and
o   Old world expresses pairing of wine with local foods
o   Expresses region
-       New World
o   Is labeled by name of grape and can expect that grape as the core
o   99.9% of new world wines are European but in different places trying to replicate the diet, lifestyle, and food pairings of native lands
o   New world drinks to get drunk and have fun
o   Makes wine that’s ready to drink now, fruit-forward, manipulated by winemaker
o   Expresses grape/winemaker

Udemy: Body & Balance
-       Wine Components
o   Body: tactile sensation, mouth-feel
§  CO2 gives more fullness and fills mouth, alcohol has hot, prickly, creamier feel
o   Balance: harmony in wine
§  Acids and Tannins
·      Acids (tart)
o   Citric acid (orange, lemon, lime), malic acid (green apple), tartaric acid (highest concentration in wine grapes)
o   Without acid, wine is flabby
·      Tannins (dry, puckering, feel is identifiable, dries out mouth, straight black tea/cinnamon does the same effect)
o   Not existent in all wines, mostly derived from skins and seeds of grapes, can come from oak barrels (how whites get tannins)
o   Young wines can be too aggressive
§  We age wines so that tannic components will soften (Bourdeaux/Zinfandel/Malbecs need time)
o   Darker wines are more tannic
§  Alcohol and Sugar
·      Residual sugar
o   Not existent in all wines (dry, fuller wines have none)
o   Whites have more than reds
·      Alcohol (created from sugar)
o   Adds body, creaminess in wine
§  Luscious full flavor (fruit, jam, etc.)
§  Raising one means raising the other to stay in balance (higher acids/tannins = higher alcohol/sugar)

o   Finish: what is left after swallowing (e.g. vodka has long heat finish)
