Effects of organic viticulture on carabid beetles

Effects of organic viticulture on carabid beetles

Background & Aim Agricultural intensification is a major cause of biodiversity loss. Organic farming may counteract the loss of species, however, knowledge about its benefits for perennial agroecosystems such as vineyards is incomplete. Researchers, therefore, analysed the effects of organic viticulture on carabid beetles, a frequently used indicator group in agroecology. Methods &...

The effects of microwave treatment of grapes on wine chemical composition

The effects of microwave treatment of grapes on wine chemical composition

The objective of this study was to evaluate the effect of microwave treatment of crushed grapes on the yeast population of the must and on the development of alcoholic fermentation, as well as on the extraction of different compounds from the grapes such as polysaccharides and amino acids that can affect the organoleptic quality and stability of the wine.   Experimental layout Cabernet...
