Of all the mandarins in Wakayama, the Natsu Mikan, or "Summer Orange" is the most prestigious. The oranges are squeezed with the skin left on, giving this sake a certain bitterness mixed in with the sweet, but more importantly, it allows this drink to capture more of the zest flavor. This organic, and vibrant fruit sake is only available seasonally, and is best served chilled. Perfect for a hot summer day.
