The documentary Our Blood is Wine, mentioned in my previous post, has a couple of clips from the 1966 Georgian film Falling Leaves, showing scenes of winemaking in Soviet Georgia. I was motivated to find out more about this film, and discovered it on YouTube with (sadly rather sparse) English subtitles. You might need to turn the English subtitles on, in the settings for the video.
At a simplistic level, Falling Leaves can be used to illustrate the way that Soviet industrial winemaking trampled over Georgian rural traditions, and that might be all that is required of it by a wine-lover with an interest in Georgia. However, the themes of the film run deeper, and if you are interested in exploring the extremes of those depths I can only refer you to the analysis given in an this essay. Or you could just watch the film and enjoy what you can.
