2. On the sorting tables, the grapes are
examined and unwanted berries and foreign items like leaves and insects
are removed by hand.
3. The grapes are taken by conveyor belt with
a constant, feed to the destemmer that works so gently that the grapes are
NOT squeezed. It only breaks the skin of the berries.
4. The grapes are transported (not pumped) in
a bin by forklift and poured into stainless steel fermenting tank (filled
with nitrogen gas to prevent excessive contact with oxygen) where it is
cold-soaked for 24 hours. To improve the flavour extraction, only sulphur
and enzymes are added during the first 24 hours.
5. On day two pure yeast is added. The
fermentation temperature in the tank is monitored and kept between 28 and
30 degrees Celsius, resulting in optimal fermentation. During primary
fermentation, which may last five to seven days, the must is
<I>punched down<I> at regular intervals to ensure good skin
contact with the juice and to extract all the flavours, tannins and colour
from the skins. The must (sugar) is converted to wine, which contains the
alcohol while the carbon dioxide escapes into the air.
6. After primary fermentation the
free-flowing wine is drawn by gravity to the tank in the hoisting tower
that's been dropped to the bottom of the shaft, six metres below the
cellar floor.
7. The skins (the must) that remained in the
fermentation tank are scooped up and carried to a gentle, hydraulically
controlled basket press where just the right pressure is applied to
extract the desired portion of tannins from the skins (The skins hold the
last 10 percent of the liquid content of the grapes).
8. The basket press wine (more
tannin-structured, arresting and forceful in taste) is drawn by gravity to
the tank at the bottom of the hoisting tower, where the free-flowing wine
(softer and gentler on the tongue) is waiting. The tank is hoisted to a
height of six metres above the cellar floor, from where the wine is drawn
to a tank for secondary fermentation, which may last 7 to 21 days.
9. The wine is then transported (by gravity,
of course!) to small barrels (225 litre capacity) made of new French and
American Oak for a maturation period of at least 12 months. These barrels
are stored in an air-conditioned cellar where a cool 16 degrees Celsius is
maintained.
10. The blending of the five varietals may
occur before or after maturation. The final blending (the exact
proportions of the blend) is determined after various sampled blends are
tasted.
