Consequences of Climate Change on the Quality and Stability of Spirits – Part 1

Climate change spares no domain, and the production of spirits, especially their aging in barrels, is no exception. The influence of climate variations on the organoleptic properties and stability of finished products is becoming a key concern for quality-conscious producers.
To understand the impacts of climate change, it is essential to revisit the origin of the compounds that form the very essence of spirits. Since only volatile compounds from the fermented matter remain in the distillate after distillation, this first article focuses on the origin and organoleptic impact of these compounds.

Blending of eaux-de-vie, a very strange phenomenon of contraction

When diluting a hydroalcoholic mixture with water, the final volume is lower than the sum of the volume of water + the starting volume.
This article explains its origin. He presents a study which demonstrates that in the case where analysis by distillation requires dilution, it is nevertheless possible to obtain good precision in the measurement of the alcohol level.
