In 2006, Francesc Grimalt and Sergio Caballero set up 4 Kilos Vinícola in Mallorca. Its name comes from the initial investment of both founding partners in the former Spanish currency, pesetas (in slang, a million pesetas was called a kilo). This winery produces wines which reflect the strength of grapes and their nuances, but with a different approach and presentation.
Francesc Grimalt is a winemaker, mainly known for rescuing the local grape variety Callet in the Balearic Island wine scene. Sergio Caballero is a musician, founding partner, co-director and responsible for the image of the advanced music and multimedia arts festival SÓNAR. Their work at the winery changes each year depending on the harvest.
First, the grapes are selected at the arrival to the winery. Both the alcoholic and the malolactic fermentation can be conducted in oak and in stainless steel tanks. The length of the ageing in wood, the kind of oak used, the size and the age of the barrels can change from one year to another. Their winemaking concept is based in the interaction of strain-soil-climate-growth. In many vineyards, native vegetation covers are used in order to obtain more concentrated grapes, a better ground porosity and an increased microbial population. At the end of September 2006, in the garage of the fellow winegrower and with few resources but with excellent grapes, they managed to produce their first vintage: 4 Kilos 2006.
In 2007, along with Apolónia Viticultors, they transformed an old sheep farm located in the outskirts of the municipality of Felanitx into a small winery. That is where the harvest was made for the production of 4 Kilos 2007 and where they started their new project: 12 Volts 2007. In 2009, they produced Gallinas y focas for the first time. It is a wine with a rich human content, which resulted from the cooperation with Amadip esment, an organisation that works with disabled people which aims at improving their life standards and their families' so that they have the same opportunities than the rest of the citizens. The winery's last project is Grimalt Caballero, a very personal and direct way of understanding the local grape variety Callet.
