Ok, I give up. What does "DGT" mean?
as in "This flake is the standard by which I judge most Virginias. 2010 has a nice, sweet taste without the addition of a topping, it ages with excellence, like a fine Virginia should, and it only gets better as you work your way down to the bottom of a bowl. I assume this would be an excellent candidate for your DGT effect, though I must admit I am too impatient to bother with the experiment."
