But if you don’t try it right out of the gate how do you grade the change? You might love it “fresh”.I've got a quarter pound of Newminster 400 in a jar in the back of my cellar. It has about 6 months on it now, so I'm going to let it mellow. I haven't even tried it yet. Before I break into that, Stokkebye's Luxury Navy Flake is my go-to.
