I don't know if they'll brew in space, but the rules haven't prevented people taking alcohol with them into space. In my former career I designed air quality monitoring equipment, and I had a few conversations with some people involved in designing equipment used on the shuttle. They were primarily concerned about the possible presence of toxic compounds, primarily as outgassing from components. What they found was traces of ethanol, on every flight. For obvious PR reasons, NASA never publicized the data, but a quiet investigation turned up evidence that there was some booze smuggled on most flights, going back to Gemini. No word on whether they found any trace hop aromatics.
