About 30 years ago I decided to have a go at growing tobacco, I did'nt know if would grow in the UK as no-one I knew had done it before, but to my surprise it grew brilliantly and I got a large crop, this I hung up to air dry thouroughly, after this the instructions I had been give with the seeds said it should be boiled for 10 minutes and then simmered for a further 50 minutes, this I did with a sample and it was awful so it was put into cardboard box's and put in the attic where it as remained for 30 years, this week I decided to try again and brought some down, this I moisten with distilled water,destalked it, shredded it, simmered it 3 times which removed most of the black, oven dried it until just a small amount of water remained. When I tried it in a roll-up it still tasted "green" and what I am wondering is does this need to be stored again and if so how, should it be stored damp in sealed containers or left open and for how long. I think the tobacco I grew was Virginia, Burley and Turkis if this makes any difference. Any help be greatly appreciated as I have 10 large cardboard box's and a sack to work through.
