Bump
I have been trying to figure this out also. Many juices have a tangy, strong, almost tart base note that I don't care for. Yet the are very highly recommended and loved by many people. I also think it might be ta. I've pm'd a few people and vendors who I thought might know but haven't gotten very far. I really didn't want to name the ones I don't like on the open forum because I don't want it to sound like I am cutting the vendor down and I certainly don't want to offend anyone. But I'm tired of wasting money and time trying to figure this out. I agree with Jonner that naming ones we like and don't like may help us figure out if it is ta (or what?) that gives that flavor and steer us towards juices that are more agreeable to our taste.
So I will start and hope others will join in the discussion:
I get "that" negative flavor from V4L Wow tobaccos, BWB (especially Casablanca), AVE Gorilla and slightly from Boba's, Blumist, CC Voodoo and Twisted Tobacco and I think maybe Vaperite but I can't remember for sure. I have steeped these for up to 3 months. The flavor diminishes some but is still there.
I like and don't get "that" taste from CC House Blend, KBV OMG and Phillips, The Vapor Girl or JC.
I would love to find more tobacco juices that don't have whatever that strong base note is - ta or something else? I've heard that ta gives very good/true tobacco flavor which I find odd because after 5 months analog free I am still craving a good strong tobacco like Marlboro Red. Yes, I already know you can't replicate an analog but I would like something that doesn't have a tart, vinegary, tangy flavor to it. Tobacco never tasted like that to me before.
