What Event formed many of the diverse soil types in the Okanagan GI
Dramatic Ice Dam
Where was the Dramatic Ice dam Located?
When Did the Dam Break?
-At McIntyre Bluff between Oliver and Okanagan Falls
-Broke 8000 years ago
What is a legally defined boundary for geographic regions known as?
Geographic Indications (GI’s)
Older Vines tend to produce more intensely flavoured grapes
True or False
True
What is a key element of nature that impacts the style and taste of wine
Soil
Soil type impacts the grape by helping the grape ripen faster or slower
True or false
True
What are the best soil types for ripening grapes
-dark soils
-Lots of rocks and gravel near surface: make vineyard warmer; speeds ripening
-(Drain Quickly) Good soil drainage encourage ripening
-Not too fertile
What are Less desirable trails in soil
-Clay soils that are often cool and damp; slows ripening
-Soil with excessive organic matter: this promotes production of lots of shoots and leaves. Known as excessive vine vigour which limit fruit maturation, quality tannins and aromatics.
Calcium carbonate in soil is thought to give what taste to wine?
Give a strong wet stone , chalky, and minerality taste to wine.
What is the main defining soil components of Okanagan and simlikameen valley. compared to other parts of the world?
-Glacial and non-glacial events in a wide range of soil parent material.
-happened 1200 to19000 years ago
- rest of world refer to their bedrock as the defining soil component.
what are 4 geological events that make up parent soil material in Okanagan
1.Glaclolacustrine - temp lake formed during deglaciation.
- Glaciofluvial - Glacial meltwaters
- Glacial Till - materials deposited by glacial ice
- Fluvial - Stream flood materials, non-glacial origin
what is the majority of south Okanagan soil types?
Deep coarse sand deposited by glacial outwash
what is the majority of soil type north of Okanagan Falls on benches adjacent to Skaha lake?
finer silty soils formed from deposited from glacial lakes.
What elevaltion do vinyards generally lie in Okanagan?
On mid level slopes between 300-600 meters off valley floor to avoid frost.
What geological origin of soils in Fraser valley?
Fertial flood plain soils
What geological origin of soils in Vancouver Island?
Vary from Marine sediment to glacial and volcanic soil
What are the 9 soil textures
- Gavel: 2-80 mm
- Sand: 0.05 - 2 mm
- Silt: 0.002 - 0.05 mm
- Clay: less than 0.002 mm
- Loam: sand, silt, clay
- Loamy Sand:
- Sandy Loam:
- Silty Loam:
- Silty clay loam:
What is Glaclolacustrine soil formation?
Material from glacial lakes made up of fine mixture of silt, sand, and clay.
What is Glaciofluvial soil formation?
Meltwater stream deposites: stony, gravelly and sandy
What is Glacial Till soil formation?
Unsorted deposits mixture of soils at higher elevations. Not affected by meltwater sorting.
What is recent stream soil formation?
material deposited by non-glacial streams
What is recent flood plain deposits soil formation?
stream deposited gravel, sand, and silt. subject to spring flooding.
