I've been making qwet lately, and IMO it's far superior to qwiso. The oil bath is unnecessary. You can just let it sit out for 24 hours like iso, or you can do a water bath too. I do a water bath in the oven @ 215 once most/all the ethanol has evaporated off. That evaporates any of the remainder water/alcohol off and also decarbs a bit. I cook it for like 45 minutes or so, then thak out and scrape while hot/warm. I find qwet produces a shatter/glass like product which is difficult to harvest after it's cooled even a bit. Also, I dunno about greywolf's suggestion of 3 minutes sitting in the freezer. It does pick up a lot of chlorophyll, but still tastes very good. I think a minute or less agitation with the ethanol is a better bet for a purer end product.
