Huh, I can't get plume on my cigars, I have several aged opus, 2 boxes of VSG. One of the boxes are like 3-4 yrs old at minimum. Along with a box of Oliva series V lances. Non of them have plume forming. I keep my wine cooler at 65/65'ish. I wish I could get plume. But homestly don't you want those oils to stay in the cigar? isn't that part of the cigars flavor?
