STB after cold water mimosa extraction

[Blimey]

Can anyone who is more versed in chemistry advise if doing a cold water mimosa extraction (3-5 days, then straining, filtering and letting the tannins settle then decanting) first, then adding lye to that before doing the naphtha thing is an effective extraction method?
Just wondering if it might be easier to get the spice out and produce better yields, with less gunk, or if that's unnecessary and a STB with all the mimosa material still present is just as effective.
I'm not a chemist but have some experience with Nomans Tek, and have made rather nice oral cold water mimosa brews with MAOIs. Thanks in advance.

Should work just fine, you can do a search for 'CWE' too.

Thanks. I thought it would work in principle Is it more effective/any better than just doing a standard STB with the material still in solution though?

I figured leaving the mimosa in to soak for longer before adding lye might mean needing less lye (I understand extra is used for its caustic properties in Nomans tek to break down the material), and resulting in less impurities being pulled through.
