Quarter, actually. Grandmother was Quebecois. But I was more going for the French as in French cuisine which underlines much of our understanding of food.
One could argue that HCl is design for human consumption insofar as it is found in the stomach and is used in our consumption of food. But then then the counterargument would be equally one of semantics. More to the point, I used exaggerated examples to point out the fact that we use litres to measure liquids yet being a liquid is not a sufficient condition for something to be a drink, only a necessary one.
Moreover, depending on your definition of "designed for human consumption", you could argue that the milk of other mammals are not designed for human consumption, yet we still consume them. Therein there is an argument to say that milk, specifically cow's milk, is not a drink. Also, it points to the interesting paradox that as a species we are more comfortable with consuming the milk of another animal than our own. Given the issue around breastfeeding in public as well as the idea of human milk products being marketable.
