The effect of the recycling of foreshots and feints during batch distillation of marc has been evaluated. The
distillation behaviour of ethanol and congeners was found to be unchanged by the recycle. Instead, the
chemical composition of the middle-cut fraction obtained with recycle of foreshots and feints proved to be
richer in ethanol (+4%), higher alcohols (+7%), esters (+13%) and aldehydes (+10%)
