Q

Most Canadian vineyards are planted next to what geological feature to moderate temperatures? What are the three benefits depending on season (3)

A

1) Near lakes
2) The lake effect reduces the risk of winter freeze
2b) In spring the water heats up slowly delaying budbreak usually until after the risk of spring frosts.
2c) It then retains summer warmth into the autumn, extending the growing season.

Q

How are the vines naturally protected from the cold winter air?

A

The moisture from the lakes evaporates and meets the ambient cold air production precipitation in the form of snow offering cover to protect the vines and insulate them.

A

1) Bury their vines

Q

Ontario’s vineyards are mainly planted on or near the shores of which two of the Great Lakes

A

Erie
Ontario

33
Q

Describe the soils of Ontario

A

Clay and sand

The areas around the lakes have a high concentration of limestone from an ancient seabed

34
Q

What are the three primary appellations of Ontario?

A

1) Niagara Peninsula
2) Lake Erie North Shore
3) Prince Edward County

35
Q

Name a significant producer in Ontario?

A

Inniskillin

36
Q

What is the largest appellation within Ontario?

A

Niagara Peninsula

37
Q

What is the Niagara Escarpment?

A

A north-facing limestone bluff which rises to around 100 metres above the level of neighbouring Lake Ontario

38
Q

What are Ontario’s two most planted white vinifera varieties?

A

1) Chardonnay
2) Riesling

39
Q

What four black vinifera varieties can be found in Ontario?

A

1) Cabernet Franc
2) Merlot
3) Pinot Noir
4) Gamay

40
Q

Ontario is one of the deepest of the Great Lakes, meaning what?

A

It takes longer to warm
up in the spring, and takes longer to cool down in the autumn

41
Q

How do the lake and escarpment provide warming air flow in winter and cooling air flow in the summer, prolonging the growing season and reducing the risk of fungal disease and frosts? (4)

A

1) During the winter, the land away from the lake cools quickly.
2) Cold air above this land flows down the slope of the escarpment under the influence of gravity.
3) At the same time relatively warm air over the lake rises and flows inland.
4) As cold air flows down the escarpment, it is replaced by the warm air above.

42
Q

What are the two regional appellations of Niagara Peninsula that fall within its overarching boundaries?

A

1) Niagara Escarpment
2) Niagara-on-the-Lake

43
Q

Why is Niagara Escarpment appellation the coolest part of the Peninsula? (2)

A

1) Altitude
2) Cooling lake breezes

44
Q

What area does the Niagara-on-the-Lake appellation cover?

A

A large area of the relatively flat land along the shores of
Lake Ontario, directly to the west of the Niagara River

45
Q

Why is Niagara-on-the-Lake slightly warmer than Niagara Escarpment?

A

The proximity to the lake reduces the drop in night-time temperatures and means autumns stay warmer longer.

46
Q

Niagara-on-the-Lake also produces the same varieties as Niagara Escarpment but in what style?

A

Slightly riper and fruitier

47
Q

Why is winter freeze more of a concern in Lake Erie North Shore than in Niagara?

A

Lake Erie is the shallowest of the Great Lakes and therefore warms up more quickly in spring but cools down more quickly in autumn than Lake Ontario

48
Q

Where on Lake Ontario is the Niagara Peninsula?

A

South-west

49
Q

Where on Lake Ontario is the Prince Edward County?

A

North-east

50
Q

Is Lake Erie North Shore warmer or cooler than Niagara?

A

Warmer

51
Q

What is Ontario’s most northerly appellation?

A

Prince Edward County

52
Q

What is a regular concern for viticulture in Prince Edward County and why?

A

Winter freeze

Due to latitude

53
Q

What aids ripening in Prince Edward County?

A

The vineyard area is situated on a broad limestone plateau with a stony topsoil that conducts heat and radiates it at night

54
Q

On which side of Canada is Ontario?

A

East

55
Q

On which side of Canada is British Columbia?

A

West

56
Q

What two varieties are most common in Prince Edward County?

A

Pinot Noir
Chardonnay

57
Q

Are British Columbia’s vineyards north or south of Ontario’s?

A

North (48°–51°) resulting in an even shorter growing season, but longer days resulting in warmer conditions and riper fruit

58
Q

What is the most planted black grape in British Columbia?

A

Merlot

59
Q

What is the most planted white grape in British Columbia?

A

Pinot Gris

60
Q

Describe Pinot Noir grown in British Columbia compared with Ontario’s

A

Riper and fruitier than Ontario with relatively high tannins

61
Q

Describe Merlot grown in British Columbia compared with Ontario

A

Tends to be more full-bodied than that in Ontario, with higher tannin levels, higher alcohol and riper fruit flavours.

62
Q

Name a significant producer in British Columbia

A

Le Vieux Pin

63
Q

If named on the label, what per cent of the grapes must have come from that appellation of British Columbia?

A

95 per cent

The remainder from elsewhere within British Columbia.

64
Q

What are the two key appellations of British Columbia?

A

1) Okanagan Valley
2) Similkameen Valley

65
Q

What moderates the hot summer and cold winter temperatures of Okanagan Valley?

A

A chain of lakes, most notably Okanagan Lake in the north (smaller than in Ontario)

66
Q

How can the Okanagan Valley be splitand what are the corresponding soil types?

A

1) North - glacial deposits of various loam
2) South - desert-like sandy where irrigation is essential

67
Q

What is the climate of Okanagan Valley?

A

Extreme continental climate with cold winters, risk of spring frost and very warm summers

68
Q

What role other than moderating temperatures do BC’s lakes play?

A

Irrigation due to low rainfall

69
Q

At what altitude are Okanagan Valley vineyards planted and what role does it play?

A

1) Around 300–600m
2) Diurnal range - cool nights as very hot days

70
Q

What five varieties are best suited to the northern end of the Okanagan Valley and on east-facing slopes that are shaded from the afternoon sun?

A

Pinot Noir, Pinot Gris, Riesling, Chardonnay and Gewürztraminer

71
Q

What four varieties are best suited to the hotter southern end of the Okanagan Valley?

A

Merlot, Cabernet Franc, Cabernet Sauvignon and even Syrah

72
Q

The climate of Similkameen Valley is similar to Okanagan, but why is it hotter? (2)

A

1) There aren’t any lakes to moderate temperature
2) The mountains also trap heat in the valley later into the evening.

73
Q

What are the four main varieties of Similkameen Valley?

A

Merlot, Pinot Noir, Cabernet Sauvignon and Chardonnay

74
Q

What are the three western appellations strongly influenced by the Pacific Ocean?

A

1) Vancouver Island
2) Gulf Islands
3) Fraser Valley

75
Q

What is the climate of Vancouver Island, Gulf Islands and Fraser Valley?

A

Cool, maritime climate moderated by the Pacific Ocean.

76
Q

What variety is best suited to Vancouver Island, Gulf Islands and Fraser Valley?

A

Early- ripening most notably Pinot Noir

77
Q

Demand exceeds supply and Canada is still a large net importer of wine. Why?

A

Due to relatively low production and the inability to produce certain styles of wines (e.g. the full bodied, very ripe wines of lower latitude climates)

78
Q

Where is most Candian wine consumed (excluding Icewine)?

A

Domestically (and within the province it’s made)

78
Q

Why is tourism and cellar door purchases very important for Canadian wineries?

A

Some provinces disallow direct to consumer shipping from Canadian wineries
