Canadians love to eat table grapes( $500,000,000/yr). Why then are our vineyards only doing wine grapes? Seedless grapes are Canada's #1 imported food( in fresh, dried and juiced form). We have hundreds of grape farms(vineyards) from Nova Scotia to BC....producing the more fragile vinifera wine grapes( very input intensive) ...but where are the Canadian vineyards producing the much hardier seedless table grapes? Agriculture statistics lists total Canadian production as zero.........so the $900,000,000 Canadian consumers spent on seedless grapes in 2014 all went into foreign pockets...would be nice if more Canadian farmers started producing food that Canadians want to eat...we now import 90% of our fruit, nuts, berries and veggies...no wonder Canada now imports more food than it exports! Young farmers are being given lots of excellent advice on how to farm but very poor suggestions on what to grow. Seedless grapes should be part of the discussion when farmers are considering a crop change. Farmers work hard to get a $300/acre corn crop and spend that $300 on inputs...not a very profitable venture....yet seedless grapes that can produce $40,000/acre are ignored. 
Earliblue is best blue seedless to start...and then add red seedless Somerset and maybe green seedless Polar Green.  Our Farm offers the most diverse hardy table grape selection in Canada...no excuses.....start growing "made in Canada" eating grapes.
