I know nothing about these kits except that they are sold at the Superstore in Western Canada. I don't think they are available at Superstores in Ontario.
Nearly every kit is designed to ferment to dry. Some kits will include a sweetening pouch to be added after fermenting to dry, if the manufacturer feels that that wine is typically not dry. EQ Zinfandel Blush.
I would not expect a sweetening pouch in the varieties you mentioned.
