It works and can yield a nice golden oil I’ve done it many times but the evaporation process leaves little/no terpenes and alcohol tends to pull undesirable things like waxes and chlorophyll. If you evaporate under vacuum it would help immensely.
Keep the alcohol cold as hell and wash quickly helps prevent pulling undesirables but it’s far less efficient than butane, overall.
For home use, though, making rosin from bubble hash or open blast BHO are your best options.
