Pistachio Shells Rapid Aging

[LabDistiller]

My spirit was overpoweringly flora, to a degree I really didn't like. I boiled, then oven roasted those shells, they range from black to almost pale.
After 2 days the color is like this, the smell is a bit nutty now and the floral notes have been tamed. Overall it did really improve the nose, will filter it (cold filtering) after 2-3 days as I am afraid the pistachio will overpower if I leave it longer.
As for the flavor I am the worst person to ask lol, my tongue can't differentiate alcohol flavor easily.
