Which of the following refers to '特別本醸造酒'?

The term '特別本醸造酒' translates to 'Special Honjozo Sake'. This designation indicates a particular classification of sake where the brewing process includes the addition of distilled alcohol. The term '特別' (tokubetsu) signifies that this is a special category of honjozo, which typically means that the rice used is polished more than the standard level for regular honjozo sake (which usually requires a polishing ratio of at least 70%).

In this context, 'Special Honjozo Sake' is created under specific guidelines that differentiate it from regular honjozo, elevating it with a unique character and flavor profile. This classification allows for a more nuanced expression of the sake's aroma and taste, often resulting in a richer and more complex flavor compared to its regular counterpart.

Other choices, while they might reference aspects of sake, do not accurately reflect the specific definition and classification associated with '特別本醸造酒.' Such distinctions in sake classifications are essential for understanding the nuances in flavor, aroma, and production methods.
