I'm really enjoying this kava, as the other review noted, it's pretty balanced, but also potent. It's got a nice mood lift, as well as nice heavy effects. Puts a smile on my face and melts my anxiety away, as well as loosening my muscles and helping me sleep.
The taste of the Bir Kar is a little less appetizing than something like the koro island, but it's all kava, so it's kind of expected that it's not going to taste good.
Highly recommend this one if you're looking for something strong and balanced.
