Saturday, I traded massages with one of my almost classmates from Massage School. I was in the "Day Class" and she was in the "Night Class" (they also met on Saturday mornings...).
She agreed to be my guinea pig for the grape seed oil.
Grape seed oil.... that's a lot of seeds for oil. I mean with apricot pits, we know they're pretty big. But grape seeds? wow. SO tiny. (If I see celery seed oil as an option out there, I may just freak out).
I googled grape seed oil, to see what I could learn.
Wikipedia tells me that it is a by-product of wine making; that it is higher in linoleic acid than many other carrier oils (oils used, for example, to "carry" essential aromatherapy oils - which are too strong to use undiluted); and that it's sometimes used as a shaving lubricant. They don't tell me much about how it's made. (They also tell me it's good for cooking and has a high smoke-point, but that's not why I'm here).
Other googling tells me that one uses an oil expeller, but I didn't dig hard enough to find out how those work. There is also, evidently a chemical method out there. I got enough to know that I'm unlikely to be making my own grape seed oil any time soon -- and that many wineries actually do make their own.
Anyway, I gave my friend a massage with the grape seed oil. It's thicker than the Apricot Seed, but not as thick as the jojoba. That thickness meant that it was a bit slicker, and thus better for gliding strokes than the apricot, but not as good for deeper work. Of course, as with all oils, some of that depends simply on how much you use.
It's clear that I'll have to do an oil-off once I've tried them all once. I'm ranking them, sort of. But in the end, I'll have to retry them all to compare the ones I've liked with each other KNOWING what I thought of the others.
