Hi all, pretty new to the forum but this is something I have a fair bit of experience with. With yaupon being the most common species on my property, I have naturally tried various versions of it. Overall, yaupon has an extremely similar taste profile to “regular tea”, but with much less bitterness. This is excellent news because you can put less sugar in the end product.
To understand how to process it, you need to think about what kind of product you want to consume. The skillet method will result in something more akin to black tea, while a dehydrator on ~140 degrees overnight will result in something more like green tea. Dehydrator on ~105 for 24 hrs is closer to white tea. These are not apples to apples but a decent starting point. There is a bit more to the way Asian teas are made. Main goal is to get the leaves dry and crumbly to the touch, even if the leaves are still green in color.. Any moisture remaining and they won’t store well.
Another factor with yaupon is that it is the ONLY plant native to North America which actually contains caffeine. This caffeine is heat soluble, which means that eating a handful of raw yaupon leaves straight off the shrub will net you exactly zero caffeine. You have to roast it or heat it in some way. As a result, you are going to get higher amounts of caffeine from the “black tea” version. A cup of strongly brewed black tea will give you the same or slightly more caffeine as an average cup of coffee.
Once you are done roasting, simply slide your fingers down the stems and the brittle leaves will fall right off of the stems. You can then grind them in a mortar and pestle, coffee grinder, blender, etc.
As for the black drink, most sources hint that the yaupon would be roasted dark, stems and berries included. This is backed by the fact that yaupon was a highly valued trade commodity for indigenous people which was found hundreds of miles outside its native range. Yaupon keeps for maybe a couple of days if not dried. I don’t have any experience eating the berries, but supposedly they will induce vomiting, as would high amounts of any strongly flavored drink.
And I believe that is the most I have posted on this forum.
