What does the term "tate" mean in sake serving?

The term "tate" refers to a vertical pouring method in sake serving. This approach is characterized by pouring the sake straight down from a height into the glass or cup, typically allowing the sake to be aerated slightly as it is poured. This method is often used for visual and aromatic enhancement, allowing the drinker to appreciate the fragrance and character of the sake more fully upon serving.

The other options, while related to sake, do not describe the "tate" method correctly. The horizontal pouring method is not characteristic of "tate," as it implies a lateral movement, which is not the focus of this term. Similarly, serving sake warm pertains to temperature rather than pouring style, and methods of sake aging deal with how the sake is stored over time rather than how it is served. Therefore, understanding that "tate" is specifically about vertical pouring clarifies its significance within the context of sake serving techniques.
