Advanced Sake Professional Practice Test

Junmai Ginjo sake is characterized by a specific level of rice milling, which plays a crucial role in defining its flavor profile, aroma, and overall quality. For Junmai Ginjo sake, the rice used must be polished to at least 60% of its original size. This means that at least 40% of the outer layers, which include fats, proteins, and other impurities, are removed during the milling process.

The emphasis on milling to this specific degree is significant because the outer layers of the rice tend to contain compounds that can negatively influence the flavor and purity of the sake. By removing these layers, a more refined and aromatic sake is produced, which is a hallmark of the Junmai Ginjo category. The result is a sake that often exhibits fruity and floral characteristics, with a smooth and clean finish.

In contrast, higher milling percentages like 70% or 80% would categorize the sake as Ginjo or Daiginjo, respectively, which are expressed through even more refined flavors and qualities. Therefore, the definition of Junmai Ginjo lies firmly at the 60% milling standard, distinguishing it from other sake types with different milling requirements.
