I'd love to hear his opinions on it, Cosmic.
I started using this method when told about it from RonniB from Nightowl Pipeworks several yrs ago.
Charles Rattray used heated blending tables back then in Perth. Robert McConnell pan fired his Virginias (along with others).
Even the original Redmond Balkan Sobranie supposedly used a special Virginia technique that has not been replicated today. Can't verify the Sobranie/Redmond thing, but the Rattray thing is true.
This is totally different from tin baking. I'd never bake a unopened tin in the paper cradle they're incased in. You're baking the chemically infused paper into the tobacco. Many say they have had no ill effects, but smoke a hundred tins of it and let me know. lol.
There's many speculations on these techniques but, as you know, being a grower and experimenting with heat and pressure, there are some true benefits.
