Just had a look - the Capella one has a poor review regarding chocolate flavour strength vs. the mint, the DV one has hints of citrus & nutmeg in it
- but worth a try perhaps, and although I see no reviews for the One on One, I see a lot of chocolate ones on their own website - I had to search for the Chocolate Peppermint Candy, but it is there. I haven't had a chance to look for any reviews elsewhere, but they have a huge range of concentrates and give a percentage suggestion for each:
Concentrated Flavor | One-on-One Flavors
I'll ask Karl if the MCV concentrate will be available occasionally or to order - I'd rather be able to get that than have to do a lot of hunting around for an equal ..which likely doesn't exist due to the 'vapetto' angle, and even if I knew how to get that added, I don't want to get too involved in mixing various flavours together if I can help it.
Did you see the new flavour announced earlier: Grandmas Lemonade? I have ordered a bottle to see what it's like - 80% VG, so fine for me if it has a good flavour.
I also ordered a few concentrates: Toasted Almond, Bavarian Cream & Mocha. I could actually imagine all three of those mixed in varying quantities.
Wish I had more time (and patience) to 'muck around' with these things!
