4.Subject product review

4-1. YOIYO <Mars Tsunuki Distillery> Single Malt

I think it is a bitter and heavy marriage that has not been seen in YOIYO so far.
I think we have created a bitter and heavy marriage that has never been seen before.
First of all, we would like you to take your time and immerse yourself in it on its own.
And for Mars whisky lovers, I would like to recommend
Komagatake and Tsunuki tasting with this YOIYO.
Komagatake is clean & rich, Tsunuki is deep & energetic.
And then there is the aggressive taste of YOIYO original covered with chocolate.
Tsunuki, YOIYO’s original blend with an aggressive taste.
Please enjoy the difference in taste as if you were on a trip to each place.
Tatsuro Kusano, Blender, Mars Tsunuki Distillery

Taken from Lotte’s official website

A unique 6-year-old cask with a sweet and sour red fruit aroma is used as the key malt, and multiple peaty casks are mixed to create a single malt that is not too cohesive.
By wrapping it in YOIYO’s first semi-bitter chocolate, in which the cocoa stands out, a powerful piece was created that complements each other.


Tsunuki Distillery’s whisky is characterized by its robust and heavy body, so it is easy to match the sweet bitterness of the bitter chocolate. The use of 6-year-old casks shows how serious they are about this whisky. I would definitely like to taste it.
