How did it start ?? Foundation was laid after the Cool Climate Meeting in Rochester ,NY Increased interest in “sustainable” aspect of Viticulture and Wine-making. One research trial looking for a good home Stake holders that dared to look into the future. “A few (good) enthusiastic persons”

Visit in Harrow Fall 1997

Search for new varieties

Bring varieties from

anywhere and make a trial

At least 5 years to

establish a field-trial

Cost before start-up Start with seedlings Define the goals Watch and check After 5 years ready for

wine-making trials

Only Regent survived

Orion, Sirius,Phoenix did not make it

Found Hibernal, Pollux

and Bianca are already in Ontario

Hibernal= GM 322-58 Received Cabernet Foch

from BC

After 3 years 6

individual plants for propagation

HG01 - HG06 Wine-making after 5

years

Start of phase 2 with 12

Some Weather data from 2007

Rain fall in August was

7 ¾ inches , half from Aug.7-9

Before the rain was a 5

week drought with periods of high humidity

Wet spring Early bud break and

bloom

Sprayprogams 2007&2008

Reduce sprays without

compromising fruit quality

Determine key sprays

and find guide-lines

Put the sustainable

protocol to the test

After Bud break Pre-Bloom After Bloom(clean up) Berry closure
