This was the health advice given about wine consumption in 1930 here in the Midi.
I don’t think we would any longer recommend giving it to 4 year olds, even diluted, or say up to 2 litres a day would be good for health but, otherwise it seems closer to modern thinking that one would expect.
NB Pasteur preferred it to water as a health drink and he was no daw in the health fields.
