I've had my little sample bottle of Prime 15 that I got from a friend here on ECF early this week. I had tried it in a carto that I had run a couple other juices through. I filled it as soon as the carto went dry. I didn't really like it. It tasted like plastic.. But I couldn't tell if that was because it had mixed with the previous juice. The previous juice was one that I had liked. So, I was curious to try it in a new carto. Thats what I did earlier this evening and I learned that Prime 15 tastes nothing like plastic. It tastes like a roasted... A roasted.... I can't quite put my finger on it... But I want to say, a roasted butternut squash. lol. A very very light in flavor roasted butternut squash with some type of smokey notes... I'm not sure how to explain it. I will try it as soon as the carto I'm using dies. I'll put it in the new carto I tried it in tonight and I'll write a review in my blog. Until then, my memories of it are clouded but it tasted roasted... maybe roasted squash? smokey, light, roasted squash? lol
