With all this information, we determine the ideal moment for the harvest, deciding at the correct time the patches we should harvest and when this should happen.
According to these parameters, we classify the grapes into different qualities eliminating the ones that do not reach the existing standards of our wines.
To continue, the vine bunches are going through our stainless steel circuit to separate the fruit from the stem. The red grapes go directly to the fermentation deposits. The white grapes go through the pneumatic press initially to abstract the actual juice that will then go into the deposits for its fermentation.
In Viticultores de Barros winery, we have got a fermentation plant with 40 stainless steel deposits. Their capacities vary from twenty thousand to 40 thousand kilos in the case of red grapes and from twenty five thousand to five hundred thousand kilos in the case of white grape juice.
Thanks to this wide variety of possibilities, we can vinify individually a lot of batches. The fermentation is done with a control of the temperature that can be varied from 18ºC to 24ºC for the reds and from 12ºC to 16ºC for the whites.
Storage and aging in barrel
In the case of our wine “Vizana”, it starts its aging in French barrels from 8 to 12 months depending on the wine itself. Every 4 months, we proceed with gravity racking, a process that consists of passing the wine from the barrels it has been kept to other empty ones. During this important procedure we eliminate the precipitated impurities we can observe during the aging whilst at the same time we oxygenise the wine.
Once this process concludes, we extract the wine from the deposit to bottle it, leaving the impurities in the deposit.
Bottling and aging in bottle
This is to achieve the tartaric stability, which will obviate tartaric remains in the bottle.
Once this process finishes, the wine is filtered and bottled. It will remain like this in its bottle, in the winery for more or less time, depending on the type of wine. During this time the wine is refined within the bottle in order to be a real delight for the final customer when this bottle opens.
