Even with trying a whole bunch of high end juices, I go back to EC Blends Fire and Ice as my 'background' vape. I pretty much always have it in one tank or another. And it definitely has a lot of menthol to it. But it's a nice palate cleaner and very refreshing.
Also keeps me away from the sodas. It's like brushing your teeth constantly all day long. Minty fresh doesn't combine well with soda.
But pretty much any juice with 'ice' in the name has a bit of menthol, some more than others. It's a really easy flavor to work with. Also, The Vapor Chef has an Absolute Zero that's made for blending with other juices to turn them into a menthol. Then you can make it as menthol as you like without having to deal with menthol crystals.
