Veraison, the change in colour of the grapes, starts a cycle that usually lasts around 20 days. Bit by bit, the bunches will take on the exact qualities they need to become wine: mainly sugars, acids and phenolic compounds. Veraison is the moment prior to ripening, which will determine the colour, aroma and flavour of the grapes that will become our wines.
Every summer is different
The change in colour of our grapes occurs gradually, as the Tempranillo grape stands out for having one of the earliest cycles in Rioja, while the Graciano and Mazuelo varieties are usually much later. So it is necessary to go out into the vineyard and start to check on the conditions of each of our 22 parcels of Viña Lanciano.
What changes occur in the plant?
Thanks to the visible change in the colour of the bunches, every grape starts to fill with pigments that mean that it loses its chlorophyll. The grape berries become softer and more flexible. The sugars are concentrated in the fruit and acids and polyphenols start to come into balance. It is the aroma, colour, taste and structure that will be appear in the first musts. In addition, the change in colour is also significant for the plants’ extremities, the shoots, which up to now, were green and flexible but now turn more woody and dry out, becoming what are known as canes.
Ready to harvest
The grapes will ripen gradually over the following days. It is a time of observation and monitoring, of exhaustive checks on the vineyard, of waiting calmly for each variety and parcel to reach the ideal moment to commence the manual harvest and field selection in Viña Lanciano.
