In the March edition<\/a>,1<\/sup> AVIPE<\/a> presented several projects where sustainable issues in the\u00a0wine sector were addressed in different ways: LIFE\u2019s H2OLock project<\/a>2<\/sup>\u00a0to reduce water loss; REVINE\u2019s project3<\/sup> to discover new biocontrol solutions against vineyard diseases; SUSMEDHOUSE\u2019s project<\/a>4<\/sup> to implement efficiency and IA in nurseries; and REDWINE\u2019s project5<\/sup> to reduce the emissions of CO2<\/sub>\u00a0in wine fermentations.<\/p>\n The 2023 harvest in Portugal has finished. The year was dry and hot, and in some cases, only one or two phytosanitary treatments against diseases had been carried out. However, if diseases weren\u2019t a problem, pest control was, and farmers had much difficulty controlling them.<\/p>\n The REDWINE project also has the goal of studying the possible effects of chlorella as a biofungicide and biostimulant. Two trials were conducted against downy mildew and heat stress. There have been some promising results, but we will only have the final results in 2025. These trials are implemented with random blocks and consider several modalities like control, commercial solutions, and organic solutions.<\/p>\n Also, in this harvest, the unit used to capture and store CO2<\/sub>\u00a0was installed by NOVIS in Palmela\u2019s cooperative winery. It was possible to collect almost one tonne using a 20,000L tank two times. The process needs some corrections, but it worked very well. We are now ready to use it in the production of chlorella biomass and start the development of new food and cosmetics.<\/p>\n Since last year, we have also used chlorella in the white wine fining process, and compared it with bentonite, the most commonly used product in the wine sector for this process. Bentonite has a strong aggregate action, but this could also reduce the colour and aroma. So far, chlorella has worked well and suggests a possibility of reducing the amount of SO2<\/sub>\u00a0in wines. We have observed that, after alcoholic fermentation, without the use of SO2<\/sub>, wines that had chlorella in the fining process could avoid oxidation for a longer time than the ones without. SO2<\/sub>\u00a0is an antioxidant and preservative that has been used for a long time in the food industry.<\/p>\n In recent years, SO2<\/sub>\u00a0has been connected to several effects on human health, therefore, the reduction in the use of SO2<\/sub>\u00a0 in the wine sector is being encouraged. Alcoholic fermentation is the transformation of sugar into alcohol. When chlorella is under stress, like with an increase in alcohol, it can expel beta-carotene, which is an antioxidant. This explains the positive results, but more tests need to be carried out.<\/p>\nProjects to drive sustainability in the wine sector<\/h3>\n
