Picked up a bottle form Calvin's last weekend and just finished it. Since it is made here in Louisiana I had to give it a try. They have a clear rum and a spiced one and I went with the spiced.
I can't give a professional opinion but I really liked it. It has an extra kick in the spice that I got with the after taste. Obviously it's not a high end rum, but offers a nice new option for rum drinkers. It's m understanding that Martin's may have it in stock soon as well.
