-: These are De Chaunac vines
that have been cut off at the base,
and regrowing new trunks.
And several shoots have been retained
in order to disperse the nutrients and metabolites
that the vine would be producing from the roots,
which would be quite strong.
The vineyard manager will take into account
that one or two of the best shoots
will be the ones to use for the new trunks
in the next year.
So, this growth actually has taken place
in a matter of a few months after cutting the vine off
at the base.
Why cut it off at the base?
Well, the vines were becoming less productive
and although we don't know for sure
whether they became less productive because of winter injury
or grapevine trunk disease, probably a combination of both.
So this is remedial action a grower can take
to retrain new trunks and refurbish the vine
to the point where next year it should begin to produce.
Camera Person: Go.
-: The vineyard manager has tied up these trunks,
selected several of the best ones,
and these are already bringing them up
after eight weeks of growth
has taken place since the old trunks were cut off.
And this gives him some vertical growth
that will be easily managed next year.

These are a couple of examples of the trunks
that were cut off.
The vines had become unproductive.
You can see that they're very difficult to manage,
they've become sprawling around.
This one has a split trunk,
so this is definitely a non-productive vine.
Cutting them off as we've just discussed
enables regrowth that will be perfect,
easily managed by the vineyard manager next year.
