Nicolas encontré este artículo que le puede servir, no le he leído así que solo me guié por el título... "Quantifying ethanol by high performance liquid chromatography with precolumn enzymatic conversion and derivatization with fluorimetric detection"
If you have a refractive index detector, I'd recommend BioRad's HPX-87H column; many other column manufacturers produce similar ion exchange columns that are perfectly fine for this application. This column also you enables to measure other major fermentation (acetate, lactate, etc) products and sugars (although it cannot always resolve all of the monosaccharides).
An RI detector is also 'very' insensitive so the %Ethanol will have to be >0.1%. A monosaccharides (simple sugars) column is easy to kill (the method will have to be isocratic). While it has a strong backbone of DVBS it cannot tolerate a high amount of Na (ppm level) and complex mixtures.
