OK, first off: if a film has vinegar smell, keep it separated from other fims, as this syndrome is "infectitious" and contagion is almost sure to happen. Also it's a good measure to wind and rewind films like these: it won't stop the syndrome from worsen (which is impossible once the process has started), but it will slow it down; needless to say, it is a good precautionary measure to take the habit to screen/wind/rewind films in general at least a couple of times/year, as this will let the substances released by the film out instead of remaining 'inside' the spool windings like a soaked sponge.
This should be done with all non-Kodachrome stocks on a regular basis: if the syndrome hasn't begun yet, chances are it won't, provided you stick with this simple rule AND store the films in a ventilated area, with mild room temperature (between 15-20° Celsius) and humidity not exceeding 60%. Do not use cardboard boxes: they impregnate the fumes from the film, nor wrap the films in any plastic wraps/foil: the film must be able and 'breathe' if you want to prevent the syndrome to start.
Kodachrome films are less prone to this problem because of their peculiar and highly standardized preocess (including lso final washing and drying, which are critical as long as VS is concerned). Nonetheless if you care for these films the same way you do for non-Kodachrome ones, they will certainly outlive you: some early Kodachrome shots taken in the early 1930's still have excellent color. Hope this helps.
