What’s Onda®?

Onda® is a patented invention by Ghidi Metalli srl:
It has come after over 2 years of Experimentation,
led in collaboration with the Course of Viticulture and Oenology of the Faculty of Agriculture
of the University of Pisa.
It turns upside down the current techniques of wine-making, refinement an maintenance
of all types of wine, both red and white wine.

Advantages

- Suitable for all types of wine-making, both white and red;
- Reduce stress for the must respect to the current techniques;
- Possibility to modulate the Kinetics fermentation;
- Greater potential of extraction of anthocyanins, tannins, phenols and aromatic components;
- Just one container is suitable for the wine-making, the refinement and the preservation of all types of wine;
- Reduces the necessity of labour in the cave.

N.B.: Pictures and Drawings as a demonstration.

ONDA
Has come into existence the movement for quality!

Onda® is a container equipped with a patented system made up of two components:
the technical gas injection system and the motion and riddling system of the liquid of the must.

The container has a kit of insufflators placed at the base (fig. 5), for the injection of technical gases (carbon dioxide, argon, nitrogen, compressed air etc.) which allows to make the liquid mass homogeneous,
control the Kinetics of the fermentation process, the refinement and the preservation of the wine.

The motion and riddling system of the liquid of the must operated by a pneumatic ram (fig. 1),
is entirely made in stainless steel, and is made up of a pipe (fig. 2), which is split on the upper side,
and to which a disc is applied (fig. 3) as well as a control valve (fig. 4).

While the ram is working it sets the pipe in alternating motion, as a result the disc produces
a delicate movement to the liquid part of the must, while the control valve makes the liquid rise up
along the pipe which it gets to moisten the upper side of the cap. With this system the maximum extraction levels are obtained without stressing directly the cap, reducing the production of lees and the loss of aromas, besides all traditional riddling mechanical techniques, such as the use oenological pumps, pressers etc… become unnecessary.

The riddling system is totally automated and it allows to modulate the pause/working times over a 24 hour period.

The Onda® container can be used as well for the white wine making: the injection of inert gases right from the bottom (argon, nitrogen etc.)
it allows to reduce to the minimum the oxidation processes bad for the flower must and to preserve unchanged the aromas and the quality.

Onda® further allows to perform the refinement and the maturation on the lees which can be riddled from the
bottom through the injection of argon or nitrogen or oxygen in case of bad smell due to lack of the oxygen itself, and also the preservation of long-term wine through the use of inert gases (argon or nitrogen).
