Long time lurker, first time poster here.

I have been making wine for a few months now, and I just purchased a
house. I have a fairly good sized yard and would like to start a
garden or hedgerow to support my winemaking.

Does anyone have any good ideas about what I should plant? I don't have
huge amounts of space or disposable income, and I live in Saskatchewan
which is very cold in winter, very hot in summer and receives little
rainfall. Good growing season here, is generally from Victoria day
(May 22) to about Labour Day (early Sept).

My trees are fairly bare right now, but there is a lot of them so I
suspect there might be a direct sunlight issue.

Rubarb would grow well, and I know there are a few varities of
Saskatoons (local name, I don't remember what the rest of the world
calls them but they are much like blueberries) cherries, raspberries,
highbush cranberries, and apples which I could probably produce.

So my question is, what gives me the lowest cost, best volume, and most
pleasant wine. Also is there much difference between Wine Rhubarb and
the regular kind?
