I think they mean a 1 or 2 Litre bottle of water, couple bottles of wine and some beer depending on which EU country you are in, wine and beer also count toward calorie count so you need to store less food.
Instead of beer or wine, stock a few bottles of liquor. Vodka, preferably. Whisky works, but not as well. Because you can use it to barter, and as an antiseptic.
