I got it about a year ago. It was an opaque yellow solution. It is a bottle that is heat sealed in a bag and now the fluid is clear yellow/orange with the yellow opaque remnants stuck to the side of the bottle. It has been stored inside my house the entire time. 73-80 degrees. Shaking it up does not bring it back into solution. I have not opened it either in hopes that maybe Lars will take it back. There is no indication of a shelf life on the bottle to my knowledge. Much of the label is in German.
