So I guess I had to find it out the hard way not to leave liquid in a warm car. I left my johnson creek red oak domestic in my glove box a couple of days and now it has almost no flavor. In place of the cookie like flavor that originally was in the bottle is a horrible bland but somehow overwhelming metallic yuck. Fortunately I have some of there arctic menthol left (which tastes exactly like their original but with a very slight mint finish) until my order of new liquid arrives. Anyone else have a similar experience?
