 Only count nouns can be prefaced unqualifiedly by numerals or the indefinite article, and be pluralized without a category shift. When we switch from speaking of ‘a horse’ to ‘five horses’ we have not switched from speaking of things to speaking of kinds of things. However, when we switch from speaking of ‘wine’ to ‘a wine’ or ‘seven wines’, we usually switch from speaking about wine (+MASS/-COUNT) to either portions of it (-MASS/+COUNT), or to kinds of wine (-MASS/+COUNT) (Pelletier 1974). (Compare ‘The wine is over there’ to ‘Gallo sells seven wines.’) While we do say things like “We’ll have six beers,” or “I need five milks for the children,” these are understood, depending on context, as shorthand for ‘six bottles/kegs of beer,’ or ‘six cartons/pints of milk’ (Higginbotham 1995, Pelletier 1979 pp. 2–4, 2012). If you pour some wine on the floor you cannot, if grammar is your guide, count the number of ‘wines’ (+MASS/-COUNT) (in the non-kind sense) on the floor. There are no things (or at least no commonsense things, by which we individuate and track persistence) which are wines, such that there are a number of them on the floor. Even if there were, say, seven pools (or droplets, puddles, etc.) on the floor, we think the same wine remains on the floor even if the pools cease to be, e.g. if they are merged or further divided.
