These days, it seems like Mentos are more known for their reaction with Diet Coke, but I can't help but remember the goofy ads from the early 90s (or the parody music video by the Foo Fighters) where ordinary citizens solved their problems with breath mints.
This Korean flavor of Mentos was provided by Tsunami.hk. The English slogan for Mentos is The FreshMaker, but the Korean website included a few others, like That's so Mentos and Be fresh with world best seller Mentos. If freshness is your goal, a fruity flavor like Fuji Apple probably isn't the best choice, but it's an orange Tic Tac situation: these are candies, not breath mints.
The candies had an intensely powerful and realistic apple juice flavor, but the strength did hurt the authenticity just a bit. Still, the Mentos were very juicy and tart, and it was easy to knock back several in one sitting.
These would probably please anyone with a favorable opinion of apples, and though I can't say for sure that they taste like the Fuji variety, I was impressed that these tasted like apple without tasting like cider. Still, I can't imagine a worse breath mint, so you may want to pop some regular Mentos afterward, just in case.
