I can't figure this out.

If a Bordeaux blend is made up of several grapes, and terroir is so
important, does a winery that blends several grapes also own several
terroirs (plots of land) where he grows the different grapes that he uses in
his wine that he labels that is from his winery?



Thanks a lot for any who can understand my question as phrased, and answer.
