Has anyone tried reverse osmosis to fortify beer -

Based on laboratory work, it was found that the present-day thin-film composite desalination membranes can be used for partial concentration of beer solution to about 20 to 30% alcohol concentration. The water permeation coefficient for these membranes in reverse osmosis with 7.6% alcohol feed at 60 atm was about 10 kg/m2-day-atm (2 lb/ft2-day-atm).
Due to the high osmotic pressures of ethanol/water mixtures, reverse osmosis can be used only for the initial concentration of beer solution and for the final dehydration of 95% alcohol to produce 199 proof alcohol. Thus, a distillation unit would have to be used for the intermediate concentration of alcohol solution.
So 20 to 30% is possible starting at 7.6% and 95 to 99.5% is possible.
Wonder if the hop artifacts go with the water or stay behind in the higher alcohol.
What would the alcohol % in the water be ?
Cool.
