Since JFC isn’t here, I can bring up DIY. Has anyone mixed using either cactus, guava or cucumber? (Not together, I haven’t totally lost it. Yet)
Cactus adds a juicy feel to a dry mix, start at .5%, can overwhelm other flavors. Use at higher percentage for a sort of gum flavor.
Most guava flavors are sweet and add a tropical note. Pairs well with hibiscus, oranges, pineapple, and can soften the sharper notes in a mix. FLV pink guava has nice grapefruit notes, would probably be nice with your tea and cherry blossom, start low at 1%, 2.5% for a single.
Haven't had a desire for cucumber. Love peeled cukes but the concentrates all have skin notes.
