If 8,000 litres of beer are consumed by a country of 8,000 people then that's a consumption rate of 1 litre per person. Even though some of those 8,000 people are likely to be one year old babies and so not drinking any beer themselves. The actual ammount the drinkers of beer are drinking will be higher.
If 50% of the population drink then they're drinking 2 litres each, but if only 25% of the population drink it's 4 litres each for the drinkers and yet the stat you're using of consumption per person stays the same.
In 1925 drinking among women was much rarer so the % of the population that drank was lower so even though each individual drinker was drinking more, the greater percentage of non drinkers means that the consumption rate in litres per person is lower. But the average drinking person was still drinking more then they do now.
