Q

Describe the difference between a cross and a hybrid

A

• Cross
Derived from two different varieties of the same species
Pinotage = Pinot Noir x Cinsaut
Müller Thurgau = Riesling x Madeline Royale

• Hybrid
Derived from two different species of grapes
Ex: Seibel 5656 x Seibel 4986 = Seyval Blanc

Q

Terroir

A
  • Anything contributing a sense of place to a wine:

Macro-climate – sunshine, temperature, rainfall
Meso-climate – vineyard
Micro-climate
• Elevation
• Slope
• Exposure
• Wind
• Bodies of water
• Plant & animal life
• Some would add: Cultural traditions of region
• Or: the paw mark of the wine grower (H. Jayer)

Q

Maceration

A

This process, used primarily in making red wine, involves steeping grape skins and solids in wine after fermentation, when alcohol acts as a solvent to extract color, tannins and aroma from the skins (aided by heat, the amount of skin contact and time).

Cold maceration (steeping when the must is not heated), takes place before fermentation.

Q

Carbonic Maceration

A

Most frequently associated with Beaujolais, this is a method of producing light-bodied, fresh and fruity red wines. Instead of crushing the grapes and releasing the juices to be fermented by yeasts, whole grape bunches are placed in a tank and the oxygen is displaced by carbon dioxide. Fermentation starts on an intracellular level inside the berry, producing some alcohol as well as fruity aromatics. In practice, the weight of the grapes on the top crushes the grapes on the bottom and yeasts ferment the juice; the wine is partly a product of carbonic maceration and partly of traditional yeast fermentation.

Q

What are the factors that affect wine style and quality?

A
  1. Location/Geography
  2. Climate
  3. Topography/Aspect - German vineyards slopes must face south
  4. Soil
  5. Grape Variety planted
  6. Viticultural practices - sometime appellation laws will only allow certain varieties to be planted

Q

Climate

A

The composite or prevailing weather conditions in an area in general or over a long period of time

17
Q

Types of Climate

A

Macroclimate: the climate of an area like a wine region
Mesoclimate: the climate of a vineyard
Microclimate: the climate around a single vine

18
Q

Latitudinal Winegrowing Zones

A

Ideal Growing Regions 30-50 Degrees North and South Latitude

If it’s less than 30 degrees, it’s too close to the equator and it’s too hot

If it’s beyond 50 degrees North and South Latitude - then it’s too cold

19
Q

Continental Climate

A
  • cool climate
  • general climate within a large land mass, like in the middle of a continent
  • high levels of seasonality: 4 distinct seasons (hot summers & cold winters)
  • diurnality: refers to the range of temperature between day and night

If it cools down at night, the ripening will be slowed down and it allows elongation of the ripening and can yield higher quality grapes

20
Q

Maritime Climate

A
  • proximity to large body of water
  • water can moderate temperatures- so there is less of a swing between temperatures of night and day and also of seasons
  • there is more humidity and precipitation
21
Q

Mediterranean Climate

A
  • closer to large body of water - but warmer and drier temperatures
22
Q

Rain Shadow Effect

A

Requires a mountain range, mountains block the prevailing weather, the clouds, the rain, the wind are all blocked by the mountains

The vineyards on the other side end up being warm, dry and sunny
