Noun
house wine (countable and uncountable, plural house wines)
A relatively inexpensive wine sold in a restaurant, often by the glass as well as by the bottle or unmarked carafe; both red and white are normally offered.
No need for confusion, my dear Mulgrave... Beautiful wine and sour vinegar come from exactly the same source. Curiously if one leaves a bottle of wine open for long enough it will become vinegar. Happily in this house wine never survives long enough to go bad. David Gemmell
