This makes me very sad to hear about cultivated wood...
But...I have a little dream, which is to set aside a small amount of land in Sri Lanka, for the growth of very high quality cultivated wood.
The vision is very long term: growing trees on land which mimics the wilderness as closely as possible, perhaps with the consultation of artisanal distillers as to the best conditions for growth, particular plants to grow alongside the oud trees etc....pure water from some rainforest land that we own. It will not be a source of income, so there will be no pressure to rush anything, everything goes towards quality without compromise. I would only start it on the assumption that it is pure sunk cost.
Then for the harvest and distillation many years down the line, it is reserved solely for the artisans. Maybe sending the same wood to different distillers to see their unique take on it.
Anyway, with God's help perhaps it will be possible. I am quietly hopeful
