@Cossackjack:
The new FDA rules state that any tobacco product not for sale on Feb 15, 2007 will be subject to testing and certification procedures. It is widely believed in the industry that such procedures will be so costly and time consuming that any product failing that date will be forced off the market.
Greg Pease says on his website that the following blends are at risk:
"Embarcadero
Union Square
Maltese Falcon
The Virginia Cream
Key Largo
The entire Old London Series [this includes Sextant and Gaslight]
The entire New World Collection"
Over time, crops change in terms of cost, quality and supply, and sometimes manufacturers may make substitutions or adjustments. Conceivably the FDA could say that an adjusted blend, made since the beginning of time, is now a new mixture and this subject to the burdensome testing regime. That is to say, no blend is safe.
If you love a mix, hoard it now.
