This past weekend I decided to experiment and make some homemade extracts for vaping. My last purchase of juice included some plain PG and VG so I had the base to build on. I also bought 2 organic vanilla beans from Amazon and some cinnamon sticks at the supermarket. I had been reading as much as I could online about extracts for the previous few weeks. Based on that research, I decided to extract coffee, vanilla beans and cinnamon for V 1.0.
THE EXTRACTION
COFFEE
The coffee was the daily favorite for my family - Starbucks Italian Roast beans which I crushed with a mortar & pestle. I didn't want to grind too fine for this first round to keep particle sizes higher and facilitate filtration. Used a heaping tablespoon of beans, ground them up a little, and topped with about 40 ml of PG in mason jar. Added to pan with water on stove and maintained temp below boil (just a few small bubbles) for about 60 min stirring often and covered half the time. Strained three times in coffee filter, each time less sediment...man that [edited] extract is still dark. I had about 20 ml of concentrate left.
VANILLA
I started with one bean split down the middle and cut into 3 pieces in about 20ml of PG in mason jar. Added to pan with water on stove and maintained temp below boil for about 2 1/2 hours stirring often. Strained once in coffee filter and yellow and clear and had about 15 ml. I later took the remaining bean material, split and cut the other bean, and added another 30ml of PG to both and still steeping - getting a little darker every day. I've read you need 4-8 weeks minimum to get optimal flavor.
CINNAMON
One cinnamon stick in about 30ml of PG (I heard it's strong). Still sitting in PG and stir at least 3X per day and also getting darker daily but not as fast as vanilla. In 2015 there were many reported issues related to cinnamon flavors posted online related to lung, throat and mouth, including sores. All the cases I read about were from purchased juice and not sure if it's the juice flavoring or the actual cinnamon. When I get around to trying, it I'll report back.
PRE-STEEP TASTE TEST
The coffee extract tastes and smells great. I mixed about 25% concentrate with VG. I added a few drops of the vanilla extract, about 15 drops of sucralose and tried the 20 ml juice sample. It wasn't a strong flavor but I could definitely taste the coffee and vanilla and it was a little sweet. I vaped about 2-3 ml and could start seeing some fine dark (coffee) residue in my tank - early indication of future coil issues. I think that's a good start pre-steep but needs work. I tried the vanilla alone earlier today after just 2 days of steeping w/o heat and it's really, really good but the flavor needs to be a bit stronger. No cinnamon sampling yet.
NEXT STEPS
Let the cinnamon and vanilla steep more. I may add more heat over the weekend to accelerate the process for vanilla - cinnamon still worries me but will make it stronger and I'll sample soon. I might lose some breadth and/or depth of flavor with more heat but I'm impatient
I need to research filtration options. Based on my research, coffee filters are about 20-50 microns and to get all the crap out that gunks up coils, you need 2-5 micron filtration. In the future I might explore the alcohol extraction method to get around the PG saturation limitations but then I have to let all the alcohol evaporate because I don't want to vape it, despite research that indicates small amounts are fine.
I hope that adds some value for anyone that likes to tinker with extracts. This is just my 2nd post since I joined 3 days ago and look forward to following up and making more contributions.
