Description
Technical field
The present invention relates to wine making technical field, is that in a kind of Production of Wine, omnidistance dissolved oxygen is controlled technique specifically.
background technology
Dissolved oxygen in grape wine refers to molecularity and is dissolved in the oxygen in grape wine.Oxygen level in grape wine is in dynamic change, and one side reacts and is consumed with the component in grape wine, on the other hand, in brewing grape wine, storage, the process of circulation, can dissolve in because of certain operations.The nineties in 20th century, the people such as Patrick proposed by special instrument, lentamente, controlledly in wine, add micro-oxygen, and add oak chip, the condition of analogy oak barrel during aging, wine is carried out to micro-oxygen technology of slaking ageing, since then, at Grape Wine Industry, about oxygen, the research of grape wine quality impact is become common practise.Yet people pay close attention to micro-oxygen in the effect of the aspects such as help fermentation, reduction Reduction Smell, raw blue or green taste, softening tannin, softening mouthfeel, raising colour stability, have but ignored excessive dissolution oxygen to hazardness vinous.
For the weak daily wine of going with rice or bread of self resistance of oxidation, if brewage, be not good at causing dissolved oxygen excessive because of process management in storage at it, will cause a series of wicked problems such as fruital disappearance, wine body deterioration by oxidation, pigementation, shelf-lives shortening.Therefore, grasp the Changing Pattern of dissolved oxygen in whole brewing process comprehensively, and apply to neatly each operation stage, give full play to the Chen Zuoyong that urges of dissolved oxygen, become the difficult problem that each EnologistWinemaker will face.And at present in Grape Wine Industry, for measure how the to take science system of going, control dissolved oxygen, make it maintain the problems such as what kind of reasonable level also not explore a set of complete effective technical process.
