Sanctuary’s House Blend Distillate…What’s a Distillate? Distillation involves the same process that turns corn and barley mash into your favorite bourbon or crude oil into everything from the propane in your grill to petroleum jelly in your beauty products. Our pharmaceutical grade distillation setup puts raw extract under ultra high vacuum and carefully heats it to vaporize, separate, and re-condense pure cannabinoids, leaving everything else behind.
