I looooove yuzu, loooove sake, and have had many Winter trips to Japan with my mouth wide open to all sorts of local treats. This is a great light styled drink that evokes the taste of yuzushu without the impact of typical sake drinking. It is not overly sweet, and very light in tone. It's not like 'lemonade'. It is addictively refreshing. As I am off the hooch it is a great comfort to have something delicious like this to enjoy at the end of the day! I expect it would be very refreshing in summer.
If you are not accustomed to yuzu taste, it is a very unique Japanese citrus that is a bit like lemon, a bit like mandarin, a bit like grapefruit...but it's totally unique. In this drink, it's just a hint - not a citrusy overload. Very drinkable. If you are expecting a strong flavour I am not sure it will be to your taste. Yuzushu spritz is a 'soft' drink, but because it is soft I think it does make it easier to appreciate, I think.
