It has been a little lighter in color this past year - keep in mind it does change color from batch to batch. However, regarding potency, it is still the same. I bottle the product and use it regularly. One thing to note is that if you use regularly people seem to get used to the zing of it - I sure have. I can just put a couple of drops in my mouth now - where others would not dare do that. In filling the last batch I knock over a bottle and while cleaning up I got some on my hands and wrist after removing gloves. I thought I was done and missed a towel and picked up and threw it away. While washing my hands I kinda spreading it around. My hands turned red and itched for a couple of hours - like a brief hive reaction. Yep it's still strong. Hope this helps - CAOH!!!!
