Abstract

This work, relates the wine production with efficient use of water, energy and fuel, and the greenhouse gases generation. A web platform was developed, based on the results of a set of six test runs in vineyards, which production are in the range of 3 to 25 million of liters of wine per year. The following stages was considered: 1. Winemaking Stage. 2. Reception of grape in hoppers or selection tables. 3. Alcohol Fermentation, Maceration and Reassembly. 4. Take-off and pressing. 5. Malolactic fermentation. 6. Stabilization and Filtered. 7. Bottling. The process of white wine is quite similar, except for the order of the stages and the absence of maceration. The platform results are based on the experimental data, which was used to formulate a model among the wine production geographic location and utility consumption: water, fuel and electricity. At the time, the platform is based on excel and visual basic, so it can be run on any standard computer. Main results of the web platform are expressed in kWh/liters of wine, or liters of water/liters of wine, for example, parameters that are useful for the generation of opportunities to improve best practices in the industry of wine.
