"Manche Frauen trinken Wein."
These quantifier words are quite tricky as they don´t match one to one. "Some" in English can have different meanings which take different words in German (eg einige, etwas). The meaning of "manche" is some but not all. In english you could say "many Germans catch a train to work" just as well as "some Germans catch the train to work", because not all do.
