Hello.
I'm pretty new in field of tobacco growing and making tobacco products but Spirit of Tobacco has taught me a lot since I asked guidance from Him. It was my second year of growing tobacco and i had two strains - Virginia and n.rustica.
I have been experimenting with making chimo aswell and last batch came out pretty good. Although it took me 1.5 months to complete the full process from boiling material (from roots to the flower) to boiling all the liquid down and add some ash from alder and cherry tree. I use to cook all the stuff on self-made stone heater with firelogs in 30 liter metal pot that's why all the process for me took some time (3 times full pot of plant material + boiling down after straining). Mainly i used Virginia but added some of rustica for flavor and nicotine content. While boiling plant material i added some lemon juice to make it more acidic. Also on the way of cooking plant material i throwed in some marigold and rosehip flowers. After straining and boiling down the liquid (on the way boiling down i added some tobacco brandy made just by stuffing some fresh cuttings of green tobacco leaves into glass jar and cover it with brandy and let it stay in warm place couple weeks, shake every day to get it stirred up ) i add little honey for sweetener, bit tonka bean for extra flavoring and for final step if everything gets quite a thick mass almost equal quantity of ash to make stuff more alkaline so that it is easier to assimilate to the body. After ash has done its chemical process i pour blackish thick stuff on the baking paper and put it in top of oven to dehydrate a bit more until consistence is right.
Last batch outcome was 1.1 kg pure nicotine bars.
I have done my research by reading some from available sources in the internet and later on guidance from tobacco Spirit. And of course practice practice practice.
I add some pictures aswell.
