What is this entire process called? a Vinification b Distillation c Winification 2 The first step in wine production is the harvesting of grapes. When to harvest is determined by a variety of factors, one of which is the sugar level. What is this measurement called (there are other names, but of these four, only one fits)? a Brix b Helix c Glucose d Trix 3 After the harvest, the grapes are crushed and allowed to ferment. During fermentation, what is the substance that converts the grape juice into alcohol? a Bentonite b Sugar c Tannin d Yeast 4 Grape quality is affected by variety as well as weather, soil minerals, acidity, time of harvest and pruning methods. What is the combination of these effects known as? a Vitus b Lees c Rachis d Terroir 5 After the wine has fermented, fining agents are used to remove excess proteins, reduce astringency and remove particles that cloud the wine. What is used as a traditional method for wine fining or clarifying? a Iodine b Sulphur c Sorbate d Gelatin 6 Preservatives are commonly used to prevent bacterial spoilage and oxidation. What is an example of such a preservative? a Hydrogen Dioxide b Sulphur Dioxide c Potassium Dioxide d Calcium Dioxide 7 Production methods for sparkling wines (2nd Fermentation) have the purpose of introducing gas in the wine to make it "bubbly". Which gas is this? a Carbon Monoxide b Ozone c Hydrogen Dioxide d Carbon Dioxide 8 The final process is the bottling of the wine. Traditionally, what are the bottles sealed with? a Screwcaps b Wax c Stoppers d Corks 9 Which pair are byproducts of a wine's fermentation process? a Sulfites & Oxygen b Vinegar & Sugar c Alcohol & carbon dioxide d Tanins & alcohol 10 Which of the following wines should be stored in the refrigerator once opened? a White wines only b Sweet white wines only c Red wines only d Both red and white wines 11 Tannins in wine primarily come from: a The soil and sunlight b The skins, stems and seeds of the grapes c Alcohol d The byproduct of the yeast's interaction with the sugar 12 Which of the following are grape varietals? a Chianti & Barolo b Bordeaux & Burgundy c Château Latour & Margaux d Merlot & Chardonnay 13 Why would you see or hear wine connoisseurs drawing air in their mouths for a moment BEFORE swallowing? a To absorb the most alcohol b To properly judge the length of the finish c To allow for the wine to become slightly warm d To slightly aerate the wine, releasing more of its flavors 14 The "finish" of a wine refers to: a The lingering aftertaste of a wine once it is swallowed b How many glasses can be poured before the bottle is finished c The final wine tasted in a series of wines d The amount of sugar in the wine 15 If it says "vinted by" on the bottle, it typically means: a Made by b Sold By c Shipped by d Distributed by 16 People store wine on its side to prevent: a The cork from drying out b Sediment from forming c Stress on the glass bottle, which could cause it to shatter d The wine from reverting back to grape juice 17 What color of grape is a Zinfandel wine made from? a White b Red c Rose d Both red and white 18 In the U.S., for a wine to bear a varietal name (e.g., Merlot, Chardonnay), what is the minimum percentage of that grape varietal must comprise the wine a 100% b 95% c 85% d 75% 19 What is the best temperature at which to store wine? a 75 b 55 c 35 d 0 20 Who is the largest wine producer in the world? a U.S. b France c Italy d Spain 21 Tannins are an essential chemical compound for which wines? a White wines b Red wines c Rose Wines d All Wines 22 What does it mean if a red or white sparkling wine has ‘brut’ on its label? a It’s a dry wine b It's a semi-sweet wine c It's a sweet wine d It's a fruity wine 23 Which of the following is NOT used to produce Champagne/Sparkling Wines such as Blanc De Blancs or Blanc De Noir? a Pinot Noir b Sauvignon Blanc c Pinot Meunier d Chardonnay 24 We never ferment reds in the vertical tanks a True b False 25 The Thermal Jackets are used to stop fermentation a True b False 26 We use White Oak because it won’t allow any loss due to evaporation. a True b False 27 Biltmore could call their Sparkling Wine, Champagne, if we wanted to. a True b False 28 Biltmore wines are vegan. a True b False 29 We are not only the largest N.C.
