Objectives

The winemaking process is a key factor for many experiments on vines and wines and its implementation is essential to assess the quality and the characteristics of wines. The design of a device allowing winemaking for small batches of grapes (1 to 1.5kg) from the pre-fermentation stage to the fermentation in heterogeneous phase should allow:

  • To integrate the potential of winemaking at the earliest stages of plant breeding.
  • To increase and assess the potential and skills of winemaking for existing varieties.
  • To guide the plant breeding.
  • To assess the impact on wine of a large number of genotypes subject to different stresses.
  • To multiply vinifications in repeatable and scalable conditions.
  • To carry out fundamental studies on fermentation in heterogeneous phase.

Actions

Sampling
Study of quick sampling methods for small homogeneous batches of grapes.
Preparation of musts and fermentation
Design of the multi-micro vinifications robot. 
Applications
Incorporate the potential of winemaking in plant breeding and the creation of new varieties (in connection with UMT Géno-Vigne®) and understanding of interaction between yeasts and polyphenols during vinifications in heterogeneous phase.
