[Growwine] Environment Canada Degree Days Averages Back To 1961Sudbury, Ontario vs., Brandon Manitoba.xls

I'm not sure how you are getting to the numbers you report from the Environment Canada information for Degree Days 10 C.   Sudbury showing 912 and Brandon 930 seem about right  yet you have adjusted the numbers upward.

There are grape varieties (not to mention other fruit suitable to wine) that will ripen in this type of heat.  But they certainly don't include vinifera, or most of the well-known French hybrids.

The other two serious factors are frost (spring and fall) and winter minimums.  Frost can be dealt with in many ways, from planting on steep slopes through smudge-pot fires (ask about Raymond Huneault!) to wind turbines.  Winter minimums can be dealt with by either some type of more or less intensive protection measure.  But best if you have a site that has hardy vines (to the climate of that site) which will work to it.

In Peterborough there are four Env. Cda sites with full information, reporting in turn the following dd 10C:
1009
1087
1153
1206

showing that particular site within a small region can be very important indeed.

For comparative purposes Picton in Prince Edward County shows 1239 dd 10C,  Vineland Station 1334 and Harrow shows 1527

Another significant difference is that the record cold in Vineland Station is -26C, Harrow -29C, Picton -36C, Peterborough -38C, Brandon -46C and Sudbury -39C.  -39C with a limitation of 912 degree days is a poser.  

Any of the experts online want to recommend fruit of any kind suited to these limitations, assuming frost control can be done, and that a normal expectation would be -35C with 900 dd 10C?

Folk have a a look at the attached data sheet, keep an open mind as one reviews the attached viticulture support data not much of a stretch of the imagination is required.  I would strongly advocate that presently with the horticultural - viticulture and Viniculture technology that is available there is no sound reason why, except for of course the ever present eye and control of government, including stigmas and folks sitting on hands, no reason why it should not be possible to expand the grape growing territory in central and North central Ontario.  I would contend that those in the wine producing center of the universe down in Niagara should be shown were the grapes grow in the pine trees.
