The choice of organic agriculture was born following the studies that Giovanni Battista d'Orsi undertook on his path at the University of Agriculture and continued after his master degree in environmental impact assessments.
With the purchase of Casaloste in 1992, Giovanni then attended a Masters in Oenology and was able to put into practice all his skills in this matter, deciding immediately to start the production using organic farming methods.
As an agronomist, Giovanni has always considered organic farming as a system of cultivation that is not different for production, quality and efficiency, from the conventional one, but which follows a scale of priorities organized to be absolutely compatible with the environment in which it operates.
The main cultivation rules can be summarized as follows: use of cultivation practices that take into account the structure and balance of the land; use of organic fertilizers; exclusion of chemical synthesis products. The Certification obtained by institutions recognized by EU certifies the regularity of organic farming practices.
It is important to underline that organic farming does not renounce technological progress and scientific research, but combines efficiency of productivity and quality with environmental balance and sustainability.

A courageous choice at the time: first certified organic farm (1994) of Panzano in Chianti and among the first ones in the entire territory of Chianti, the choice of the Bio was a real challenge.

The conviction of the importance of the use of organic farming methods on the territory, was then shared with other producers of Panzano, with which Casaloste established the Unione Viticoltori di Panzano.
The Unione, founded in 1996, mainly links producers in a bond of friendship, sharing the same objectives of quality and respect for the environment while maintaining each one's own identity.
This common commitment has led to the recognition of Panzano as excellence in organic production with about 90% of the organic certified area of Panzano.
In terms of sustainability and respect for the environment, Unione Viticoltori has funded the creation of the SPEVIS Experimental Station, a private facility that studies advanced solutions and strategies to limit the use of insecticides in the management of organic vineyards.

The first monitoring actions, meteorological data surveys, controls and experiments on the territory, has started in Panzano in Chianti, with the intent of observing any critical issues and preventing them using only organic farming methods.
The coordination between the companies is realized through technical-practical bulletins with suggestions on the actions to be carried out in the field.
A team work that helps producers to maintain closer monitoring in the field and to find eco-friendly solutions, whose benefits are reflected in the value of the products obtained.
