Reasoned Viticulture

To practice “Reasoned Viticulture” is to put the Vineyard System at the centre of quality and production logistics. The vineyard should be considered as a defined ecosystem, whose equilibrium must be perfectly maintained in order to become the basis for producing Sustainable Quality, strongly linked to the area. A “reasoned approach to viticulture” involves considering all the primary and secondary effects of every process in the management of the vineyard so as to preserve its health, biodiversity and qualitative productivity. The use of modern technology, together with a deep knowledge of our own cultivation environment brings a guaranteed consistent and high level of quality to the product, as well as the utmost respect and seriousness in protecting the health of customers with the least possible environmental impact in the management of seasonal variability.

Precision Farming or Precision Agriculture

This is based on the development of detailed satellite photographs that are developed into vine vigour maps showing the vegetative state of the vines during different stages of the season. This type of map therefore subdivides the various plots into different areas characterised by vine vigour and quality output similar to their own. This fundamental agronomic information will enable the establishment of fertilisation plans and the management of specific green harvesting for each individual area, so as to balance production across the entire vineyard, creating the plants required to achieve the desired quality of grape.
The indirect benefits of this type of approach are as important as the direct benefit of having a healthier plant as they will ensure that there is less need for mechanical intervention in the vineyard and a generally higher level of health for the grapes. For
the grape harvest, this will result in a reduction in the use of sulphites and, in general, fewer interventions in the transformative process between grape and wine, consequently better exploiting the intrinsic qualities of the grape.
From precision farming a design idea was derived, resulting in a patent for a piece of fertilisation machinery, linked to GPS and to vine vigour maps, to nourish the vines with the right quantities, dosed plant by plant.

Grape harvesting in a controlled environment

This applies to the entire journey, from the removal of the grape from the plant to the arrival of the must inside the fermentation vats.
Each stage is undertaken in the total absence of oxygen, which otherwise would in some cases result in the partial alteration or loss of some of the grape’s more delicate characteristics.
Such a process is achieved through the establishment of modified atmospheres, or through saturation of carbon dioxide. These practices have allowed for a general reduction in the use of sulphites.


In recent years Bosco del Merlo has established a Research & Development working group, made up of resident experts, agronomists and oenologists, linked to the University of Milan thanks to Prof. Leonardo Valenti.
Amongst the environmentally themed plans already in a stage of development there are two very important ongoing studies assessing the winery carbon footprint and the containment of emissions.

In particular Bosco del Merlo is the first winery company in Italy to have a station for measuring (rather than estimating) absorption of CO2 by the vineyards. The station was installed between the rows of Sauvignon Blanc in the vineyards of Lison, through collaboration with a team from the University di Padua, overseen by Prof. Pitacco.

1) Ita.Ca® in conjunction with 50 other companies across Italy is developing an emissions calculator, in line with OIV Protocol.
The aim of the project is to apply the unique internationally recognised (FIVS and WFA) Italian method of calculation, for assessing carbon emissions and estimating the balance of CO2 in a business context.

2) Winezero: the project, overseen by the University di Padua, aims to analyse the absorption of carbon dioxide by the vineyard.
The projects innovatively combine absorption and emission calculations (which have thus far never been integrated in any other country) for this important production industry, with the intention of certifying the area subject to checks, from a carbon balance perspective.
