  1. What latitudes limit where grape vines grow best?
    • Too warm if < 30° N or S
    • Too cold if > 50° N or S
  2. What variety has smaller berries -- Cabernet Sauvignon or Cabernet Franc?
    • Petit indicates smaller berries and is usually better.
    • Cabernet Sauvignon is also known as Petit Vidure.
    • Cabernet Franc is also known as Gros Vidure.
    • Note: Vidure is also known as the Carmenere grape.
  3. What is an organic wine?
    Wines made using minimal SO2 using grapes grown without chemicsls (fertilizers, pesticides, herbicides).
  4. Why is grape skin important?
    • Grape skin contains most of the aroma associated with a grape variety.
    • Examples:
    • Sauvignon Blac has thick skin Ripe aromas include peach in warm climates and gooseberry in cool climates.
    • Underripe aromas are grassy, elderflower, cat pee.
    • Semillion has thin skin. It is a neutral wine and susceptible to noble rot.
  5. What is the difference between oxidative and reductive wine making?
    • Oxidative is fermentation in the presence of oxygen.
    • This allows removal of oxidized elements so wine can age better.
    • Reductive is fermentation in the absense of oxygen.
    • This allows the fruity characteristics to be kept intact but results in shorter shelf life.
  6. Name 5 wine faults, what they are, and how to identify them.
    • 2-4-6 Trichloroanisole (TCA) - "corked"
    • Results from tainted cork
    • Smells like wet moldy cardboard

    • Volatile Acidity (VA)
    • Results from fatty acids, e.g., acetic and carbonic acid
    • Smells like vinegar or fingernail polish

    • Brettanomyces (Brett)
    • Results from a genus of yeast, usually affecting red wine
    • Smells "horsey", leather, band-aid, urine/fecal notes

    • Excess SO2
    • Added during winemaking
    • Smells like a matchstick or wet wool

    • Oxidation/Heat
    • Results from age or poor storage
    • Smells of cooked fruit with vegetal notes, and has a flat finish
  7. What characteristics does a fine wine have?
    • Natural balance and finesse
    • Distinctive individual character within its own type or style
  8. Why swirl the glass?
    • To volatize the esters, thus release the flavor elements attached to the alcohol
    • Esters are chemicals formed by the reaction between alcohol and acid
  9. What are the 4 steps of the deductive tasting method and which is the most important step in blind tasting?
    • Sight (aka Eye)
    • Smell (aka Nose)

    • Iron: for photosynthesis
    • Magnesium: for chlorophyll

  25. What is Terroir?
    Anything that contributes a sense of place.

    Such factors include soil, location, aspect, climate, and weather (vintage, temperature, sunshine, rainfall, frost).

    Aspect refers to the vineyard's topography--which direction the vines face, the angle and height of any slope, etc.--and how this interrelates with the climate.
  26. Describe the annual lifecycle of the vine (9 steps)
    Add 6 months for Southern Hemisphere:

    • Feb: Weeping (sap oozing out of the pruned cane ends)
    • Mar-Apr: Bud-break (vines secured to training frames)
    • Apr-May: Emergence of shoots, foliage, and embryo bunches (spraying begins)
    • May-Jun: Flowering of the vine (68°-77°F is ideal)
    • Jun-Jul: Fruit Set (29-53% of the embryo bunch evolve into grapes depending on variety)
    • Aug: Ripening of the grapes (after skin turns color--veraison)
    • Aug-Oct: Harvest (earlier nearer to the equator; white grapes ripen before black grapes)
    • Nov-Dec: Botrytis cinerea (Edelfaule in Germany) -- grapes dehydrate and are subject to cold which induces chemical changes called passerillage; this can lead to "noble rot".
    • Dec-Jan: Eiswein (in Germany and Canada, frozen grapes are harvested, the frozen water is skimmed off pressed grapes, leaving a super-concentrated pulp)
  27. Why is oak the only wood used for barrel-making?
    Other woods are either too porous or contain overpowering aromatic substances that unpleasantly taint wine.

    White oak is easily bent, has a low porosity, acceptable tannin content, and mild, creamy aromatic substances.
  28. How many gallons does a wine cask ("barrique") hold?
    • Traditional sizes range from
    • 54 gallons (Champagne)
    • 59 gallons (Bordeaux, Spain)

  29. What is a tonnelier?
    A cooper (barrel maker)
  30. Where should a wine bung be positioned during fermentation?
    When fermenting white wines, the bung is always uppermost. After racking the barrels are filled to the very top and positioned so the bung is to one side, visually reminding cellar-workers that the casks are full.
  31. How do you know if oak chips were used?
    The wine label mentions oak, but not barriques, barrels, or casks.
  32. Describe the steps of vinification
    • Hopper/Crusher/Destemmer: red wines are pumped into a vat because they must be fermented along with a manta, or cap, of grapeskins; remontage or pigeage is used to keep the juice in contact with the grapeskins during fermentation; some aromatic white wines undergo prefermentation maceration in a vinimatic
    • Fermentation: yeast cells excrete enzymes that convert natural fruit sugars into almost equal quantities of alcohol and carbonic gas; optimum temperature is 85°F for red wine and 64°F for white wine
    • Pressing: free-run wine, or vin de goutte, and press wine, or vin de presse, are pumped into separate vats to undergo MLC separately
    • Malolactic fermentation: converts the hard malic acid of unripe grapes into two parts soft lactic acid and one part carbonic gas
    • Racking: draining the clear wine off its lees into another cask
    • Fining: adding egg white, tannin, gelatin, bentonite, isinglass, or casein to wine which adheres to cloudy matter and thereby clarifies the wine
    • Cold stabilization: dropping the temperature very low for a few days so harmless crystalline tartrates can be precipitated)
    • Filtration: 4 types: earth, pad, membrane, and crossflow
    • Bottling: automates cork, capsule, label, and box operations; some systems print a lot number on the bottle or label.
  33. What are pigeage, remontage, and vinimatic?
    • Systems to keep the fermenting juice in contact with the grapeskins.
    • Pigeage means the manta is manually pushed under fermenting juice using poles.
    • Remontage means pumping fermenting juice over the manta of grapeskins.
    • Vinimatic keeps the manta submerged in a sealed rotating stainless-steel tank (like a cement mixer).
    • Other methods include vats with grids that prevent the manta from rising, relying on carbonic gas to build up pressure and periodically push the manta under the surface.
  34. What is wine?
    Wholly or partially fermented fruit juice (usually grapes).
  35. What are the 5 types of wine labels?
    • Varietal: New World and Alsace, Germany, Austria

  36. What is MLC? (aka MLF)

    • Turns malic acid into lactic acid to make the wine softer.

    • Tannin (cut fatty, match bitter greens)
  51. Name 4 foods that are wine "killers"
    • Artichokes: cynarin makes wine taste sweet) so serve with wine that is tart, thin, dry, acidic
    • Asparagus: cynarin makes wine taste sweet) so serve with wine that is dry, grassy (SB), or herbal (Gruner Veltliner) or mitigate by grilling, roasting or only serving tips
    • Vinaigrettes: makes wine taste flabby so use less vinegar or replace with citrus or verjus (tart, underripe grape juice)
