I usually order 120ml of 100mg at a time...if I use half of it and put half in a 50ml brown glass bottle in the freezer...and come back say a month latter and mix a new batch of juice with the nic in the freezer...I just hate the taste it seems like it totally screws up the flavor of the juice,and is to peppery,I try and leave it exposed to air for the shortest possible time, but it still seems to oxidize...Am I a nic Queen or does anybody else have this experince.
