sake served in a masu; sake sold in a masu
Refers to sake (or occasionally other alcohol) that is either served in or sold in a small square wooden box called a masu. This is a traditional way of drinking sake, often associated with celebrations or old-style izakaya.
When I ordered masuzake at the izakaya, they poured it so generously that it overflowed from the masu.
It's our family custom to toast with masuzake on New Year's.
