Project No. 1: Selection of soils and varieties of grapes for wine export

Description

VCJF born with this project which aimed to take advantage grape varieties has been planted and planted some not found in our country for the production of wines for export. This project was declared of National Interest in 1976 and was considered one of the pioneers in raising the potential of wine for export had Uruguay and the search for new viticultural regions (Project directed by Juan Carrau Pujol in collaboration with the University of California Davis ).

This project is currently ongoing since 1993 in collaboration with Dr. Giuseppe Versibi of San Michelle Institute of Italy (with old materials Nebbiolo and Moscatel honey) and studies of old clones of Tannat original material introduced by Harriague since 1870, in collaboration with Santa Rosa SA seeds since 1995 (selection of virus-free clones with tissue culture) and the financing of the group of Dr. Carina IIB Gaggero EC in the area of molecular genetics vine clones.

Main results

First plantings of plants free of virus clonal selection in Uruguay. Opening markets for Uruguay (Argentina, Sweden, Canada, Germany, Japan, Norway, France, Italy, Spain, Poland, China, Denmark) Development of technology for the development of Tannat wine for export in 1979. First plantations Tanat virus free Uruguay clones

Project No.2: Biotechnology of winemaking. Election of indigenous yeasts for winemaking wines.

Description

Since 1985, FJC has selected another different yeast strains to give their wines characteristics avoiding the use of commercial yeasts for mass use. This project was supported by the University of Caxias Brazil and later the Faculty of Science is now continued in this area in collaboration with the Australian Wine Research Institute, Dr. Paul Henschke, with two doctoral dissertations and master.

Main Results

This project was recognized in 1992 by ICI as only winery among the 100 innovative companies in Latin America. Collection of yeast strains for different uses such as white wines, red and fermentation in Champagne.

Increased understanding of the importance of native flora in winemaking and the use of efficient yeasts in the process (There are international publications about by this company) A project CONCICYT IDB I arising from the experience gained in the development of yeast killer by this company, currently a product of this patent is in the group Dra.Elia Nunez of the Faculty of Medicine and Francisco Carrau (anti-fungal products for human use strains isolated from wine)

Proyecto No.3: Estudios y caracterización del Tannat para vinos de exportación.

Descripción

Proyecto de CSIC e INIA en colaboración con el Dr.Dellacassa de Facultad de Química e Ingeniería Edgardo Disegna para el estudio de aromas y componentes polifenolicos del Tannat. La relación de nuestra empresa con el Dr. Versini de Italia fue uno de los aportes principales para el desarrollo de este proyecto y el entrenamiento de análisis de vinos en la Facultad de Química.

Principales resultados

Primeras caracterizaciones aromáticas de Tannat, puesta a punto de técnicas avanzadas de análisis de aromas por GCMS. Capacitación de personal en manejo de viñedo micro vinificaciónes y evaluación de calidad

No.4 Project: Organic vineyard management. Waste recycling industry came biofertilizers and biocontrol fungi.

Description

In 1989 he began with the tuning method for grape pomace composting and use of these as organic fertilizer in agriculture. Consultant hired with the support of LATU Prof. Melvin Finstein Rutgers University, USA. He is currently involved with CSIC in a master’s thesis in biotechnology on the selection of downy mildew and Botrytis antagonist for use in Vid (Lic. Ximena Rabosto)

Main results

Starting a business pomace composting that after 8 years now passed by with City Garden in the production of Biofértil (biofértil LTDA). Early trials of applying a bacteria against botrytis to agronomic, project preparation in collaboration with the Faculty of Chemistry of chemical INIA.

Health wine and wine Red Tannat effect formation reactions in cholesterol and inhibition of free radical formation

Description

Since 1999 Bodegas Carrau based on a master’s thesis in biotechnology on the protective effect of wine Tannat in cancer and DNA repair reactions using Saccharomyces cerevisiae yeast as similar to the human genetic system biological model. This thesis is done in the department of biophysics at the Medical School by Nelson Brasesco.

On the other hand in inhibition studies of cholesterol formation it is working on a joint project with the biochemist and professor of Uruguayan Alejandro Giuglucci Napa Touro University California one. This project is for the study and characterization of Tannat’s different types of maceration with and without aging in barrels in inhibiting the oxidation of LDL.
