I get the feeling he is not so widely known, but in excellent critical standing. He was pegged as a minimalist early on, a tag he did not like. I have probably read about half of his stories, and some are indeed memorable and come back later with haunting images and scenes.
It is also said that he preceded each story by working out certain details in a poem. He did not have a large output, partly attributable to an early death at 50. He was an alcoholic. I have no idea whether the poem Wine was story fodder or not.
