Processing Damask Rose Flowers For Rose Water and Essential Oil
Hello friends,
And welcome to 2025 on my blog. I did a bunch of stuff over the Christmas break, so in the coming weeks you'll see what I got up to crafting and gardening wise during that time. One of the things I got up to in November and December, was to harvest, and then process my own damask rose flowers.
Damask roses hail from Syria, and their flowers have been used to make rose essential oil and rose water for thousands of years, for use in both perfumes and food. In New Zealand, damask rose plants are hard to come by, and it took me a few years to get hold of two rose bushes from small, specialty rose growers. The two varieties of damask rose bushes in my back garden are Duc De Cambridge and Isapahan.

Damask roses only flower once in spring, and their flowering happens over the course of a month. After some research, I found a scientific paper which said that the damask rose flowers could be stored at -20˚C for a month without losing any rose essential oil, in order to collect enough rose flowers to process them by steam distillation. From mid-November to mid-December, I went out into the back garden each morning, and collected flowers from my damask rose bushes, and them stored them in our chest freezer.
When flowering finished in mid-December, I defrosted my damask rose flowers and placed them inside my Air Still pot still for distillation. After filling the still with enough water to cover the roses, I began distilling the rose essential oil and rose water.
After about twenty minutes of heating, the strong scent of rose essential oil gases began filling the kitchen. A minute after that, the combined liquid of rose essential oil and rose water began exiting the pot still.
The distilling process took about an hour, and I was left with 700 mL of combined rose essential oil and rose water afterward. The amount of rose essential oil was tiny compared to the rose water, so I decided to leave the two combined for storage. I split the resultant rose water into two 350 mL containers, and gave one to my sister, who likes to make natural products for her home.
I'm really pleased with the resulting rose water, which smells lovely, and in the coming years as my rose bushes grow, I'll get bigger harvests of rose flowers each year. My plan with the rose water this year is to use it in my cold-processed soap recipe later on this summer.
Have a wonderful day

Distilling Peppermint Essential Oil and Hydrosol From My Peppermint Plants
Hello friends,
Earlier this year, in the middle of summer as I was harvesting some of my many lavender bushes, an idea popped into my head to one day extract my own essential oil from the flowers. I dreamed up so many ideas of what I could do with the resulting essential oil and hydrosol, that I knew it was something I wanted to do in the future.
I had done this many times before in the lab when I worked as a plant biochemist, but back then I had a lab full of equipment at my command, but now, not so much. I couldn't exactly call up a local lab supply place any longer, since I didn't belong to a scientific group where this was thought of as an appropriate use of said equipment. So I had to come up with better idea. I did come across alembic stills for sale in New Zealand, but the stills were very large, and there was no way I could fill up any one of their stills.
Then I came across a small pot still from Still Spirits called the Air Still. With a big base like a kettle, and an air cooled distiller on top, it was perfect for me in home use. It is typically made to make and distill alcoholic beverages like gin and rum, but the instructions also include a method to distill essential oils and hydrosols from plants. After waiting for a while, one was finally available for sale on special, and I ordered one for us. Unfortunately by this time it was the middle of winter, and there was nothing to distill yet.
When it arrived, I was quite happy with it. I did the first cleaning, and then did a trial run by making distilled water, which could potentially be helpful in a natural disaster when water is contaminated. Ever since then I've been waiting impatiently for some plant material to be ready.
And our growing peppermint plant was the first plant material ready to actually try the Air Still out on. I started by harvesting a big bunch of peppermint leaves from the edge of the plant. I washed them in water to clean them, patted them dry, and then cut them up into smaller sections to fit into the still. The total weight of the peppermint plants going into the still was 234 grams.
I popped them into the still pot, and then boiled up 3L of water in the kettle. Once I added the boiling water, I inserted the still head, and turned it on. It
was less than 10 minutes before the liquid began to come off the still as the water boiled, and there on top of the hydrosol was a fine layer of peppermint essential oil. I was so excited.
The peppermint and hydrosol came off at a decently fast rate, and it wasn't long before I had 0.6L of combined peppermint essential oil and hydrosol.
All that there was left to do was separate the hydrosol from the peppermint essential oil. I bought a chemistry separator funnel online, and was able to separate out the hydrosol on the bottom of the liquid, from the essential oil on the top.
In the end I got about 0.5 mL of peppermint essential oil, and 0.6L of peppermint hydrosol.
Considering that I only added 234 grams of plant material to the still, I thought that it was a pretty good harvest rate. It didn't take a lot of effort and time, and it's a fun project to do. I will definitely be repeating this method with my lavender and rose harvests in the future. I will be using the essential oils and hydrosols in my home, and my sister as also requested some for her to use at home as well.
Have you ever done something so completely geeky around the home, that it makes you really happy to see the results of your endeavors? I'd love to know...
Have a wonderful day
