Volatile compounds production during ripening of cv. “Sangiovese” grapes from different terroir

Abstract

“Sangiovese” (Vitis vinifera L. sativa cv. Sangiovese) is the main grape variety to be established in Italy, being the only country in Europe where this grape is commonly found. Effects of different terroir on the aroma profiles in must of “Sangiovese” grapes were investigated in two Tuscany areas to study the relationship genotype/environment. Grape volatile compounds are the main contributor to the fresh and fruity note in wines. Compounds responsible for this aroma are different depending on the cultural practices and climatic or biological factors and grape volatile composition can greatly vary during ripening. Volatile compounds of grapes are generally present in trace amounts and we used a SPME method to determine aroma composition of “Sangiovese” grapes at different times during ripening and at harvest date. For a full understanding of the process, we also described by agronomic and phenological index the ripening of “Sangiovese” in these two different areas, as well as weather data.

Changes in grape-associated microbiome as a consequence of post-harvest withering

AIM: Grape withering is an oenological post-harvest process used for production of reinforced and sweet wines. Drying can be carried out by keeping the ripe grape in traditional large, well-aired rooms (non-controlled environment) or, more and more often, in a warehouse under controlled conditions of airflow and relative humidity (controlled environment)[1].

Antifungal and Laccase-Suppressing Activity of Phenolic Compounds and Their Oxidation Products on Grey Mold-Fungus Botrytis cinerea

Botrytis cinerea causes grey mold that results in severe problems for wine makers worldwide. Infected grapes lead to quality deterioration including formation of off-flavors or browning. The latter is caused by the enzyme laccase which is capable of oxidizing a wide range of phenolic compounds. Since the use of conventional pesticides is associated with many concerns of consumers and authorities regarding environmental and health related issues and may result in fungicide resistance, the development of green alternatives is gaining more attention.
