Summer heat
is upon us 11 November 2005
How different it is from the gentler
conditions of France, muses Kobus von Ierop
Spring
started nice and cool with some thunderstorms and lots of growth in the
vineyards. But it seems as if the party is over and the heat is here.
Harvest is just three months away.
A dangerous thing
to do is to compare our growing conditions and vines to, for example,
those of France. For example:
-
I always have to
wear a rainjacket or something warm whilst harvesting in France. It
is cold, autumn, when they harvest. The season has turned and the
colour of the leaves are changing. We harvest in the heat of summer.
Even the so called cooler climates in South Africa harvest most of
their grapes during March when it is still boiling hot.
-
In France they
also have some very hot days - in Alsace in the north of France a 39
degree Celcius day is not impossible, but their heat comes before
veraison (when the berries soften and change colour). In most places
the season changes in France at the time of veraison. We have heat
before and after veraison and right into harvest. The quality of the
grape is determined more by temperaure (heat waves) after
veraison and not so much before. Cooler weather after veraison
always favours better quality.
-
In
France farmers do not irrigate. Of course they don't. Because they
don't have to, most of the time. In the last four harvests I have
been to France it has been raining right into harvest.
-
We have more
wind here, as far as I know, than anywhere in France or Italy or
California. Wind, heat and little water causes stress in our
vineyards more than anywhere I have seen.
-
The heated issue
of breaking away of leaves: Some French winemakers believe
in removing leaves around the bunches to expose the grapes to direct
sunlight. That works in France where the climate is mild before
harvest. Our pre-harvest period is so hot not even the crickets eat
during the day.
-
Low yields. Much
to say for that, but I have seen many blocks of so-called 3 tons/ha
in Europe where the other 7 is somehow just not counted!
This is truly a
country of extremes. I always get the feeling that the vineyards in
Europe are so civilised, ours are so wild! Their climate seems mild,
almost gentle, while with us the wind blows you off your feet and the
sun burns you into a head spin. What a lovely place to be, though!
