Hi Acer. I'll kick off with what little I know. Only yesterday I received my latest order from Hermitage Oils which included Tobacco Absolute. It's very dark with a rich, tenacious aroma. I made a 50% base dilution in ethanol to make it more workable because it's quite thick and I work with drops so I need to have all my materials at a similar, thin viscosity to ensure some degree of accuracy. This is only my second order from Hermitage and I'm blown away by their service: free postage to Australia on orders over £40 and Adam is fantastic and treats every order with his own unique personal touch. Thoroughly recommended.
