La présente invention concerne un procédé de production d'alcool(s), selon lequel on introduit un milieu de culture contenant un substrat carboné sucré (2) dans une section réactionnelle (1) comprenant un support (4) sur lequel sont immobilisés des micro-organismes, afin de produire par fermentation sous l'action desdits micro-organismes un moût (3) enrichi en alcool(s) et un/des gaz de fermentation, tel que le procédé est opéré en continu en phase liquide, et tel qu'on opère, pour piloter la production, un suivi de la quantité de micro-organismes vivants immobilisés sur le support sans intervention sur lesdits supports. Figure pour l'abrégé : Fig 1 The present invention relates to a process for producing alcohol(s), according to which a culture medium containing a sugary carbon-based substrate (2) is introduced into a reaction section (1) comprising a support (4) on which microorganisms are immobilised, in order to produce, by fermentation under the action of said microorganisms, a must (3) enriched in alcohol(s) and one or more fermentation gases, such that the process is carried out continuously in the liquid phase and such that, in order to control the production, the amount of living microorganisms immobilised on the support is monitored without intervention on said supports.
