Above all, this can happen to one fermentation stop or at one malolactic fermentation related to too weak sulfurization respectively. Often it is diacetyl and volatile acid (acetic acid) is formed. In a weak form, this gives the wine a buttery Note, the more pronounced the Lactic acid sting, The error is caused by sulfur dioxide and mechanically controlled by whirring the mucus. The slimy structure of the wine is dissolved by the mechanical stress.
