I am so excited about this new hobby of distilling oils and making hydrosols. My first attempt is with my own fresh lavender, picked right here on my own little farm. The water will steam the plant material carrying all the goodness from the plant into the tube and pass the coils. As the steam passes thru the lavender, it turns back into a liquid and collects in the jar. This liquid is my hydrosol! Pretty cool, uh?
