Using nanopore skim-sequencing to characterise regional epigenetic variability in New Zealand Sauvignon Blanc

Terroir method has been used for assessment of growing site in the world for years. In Slovakia actually regionalisation is used as the similar method which does not cover all the elements of wine quality evaluation however.

The aims of this study were to examine the effect of high sugar concentrations of must and copper residues on different commercial wine yeasts. Copper originating from pesticides has been known to inhibit yeast, but it’s effect on fermentation performance and VA production of different yeast strains had not been investigated in detail.

Hail damage can have a major impact on the vine’s physiological growth (defoliation, wood and cane damage) and can lead to significant yield and economic losses.

In the pursuit of increasing sustainability, climate change resiliency and independence of synthetic pesticides in agriculture, the interest of consumers and producers in organic and biodynamic farming is steadily increasing. This is in particular the case for the vitivinicultural industry in Europe, where more and more producers are converting from organic to biodynamic farming. However, clear scientific evidence showing that biodynamic farming improves vine physiology, vine stress resilience, berry or wine quality, or is more sustainable for the environment is still lacking although this issue has been addressed by several research teams worldwide.

The development of off-flavours in wine distillates, particularly those associated with the tails fraction, is a key issue in the production of high-quality spirits.
