Hmmmmmmm, I’m not sure what Tulsi is. Ok I know what google says it is, but I don’t think I’ve ever run into it before. I’m going out on a limb and assume that tulsi is the weirdness in this chai. It’s not bad just had a weird taste amongst the spices. It’s really spicy, I may have to try other Fusion Tea chai to see how they compare, but if you take that “weird” out of this it would be amazing. This is getting more mellow as it cools, the flavors are coming together more harmoniously. Glad to have tried it, not sure it will become my go to chai, but I like it (weirdness and all).
