I used my final remaining dried rose flower heads (including some leaves) and distilled using the copper alembic still (hydro distillation.
I immersed the 40 gm or so of dried flower heads in approx 700 ml of boiling water and heated over the gas stove. I had cold water going over the condenser from the start as from prior experience disllate comes out very quikcly with my littles still. Sure enough with 5 mins. I had distillate coming out. In total I collected approx 670 ml of decent hydrosol. I filled them in 125 ml bottles and labelled each with the time and number as the aroma varied from bottle to bottle. For the final amount I had a paper filter going from the still and was able to see a yellow staining on the paper (some precious otto perhaps). It really was at the end and I am sure all the water had gone from inside as the aroma was a sweet caramel, raw tobacco like with a slight hint of 'cooked. the final 50 ml was a cloudy yellow and I am going to put that bottle and the first one in the freezer to see if there was any non polar aromatic molecules. Intriguing! Enjoy! Wendy
