planning on trying a no-boil hefeweizen this weekend. I have 3 lbs pilsner DME, 3 lbs what DME, and 1 oz. of tettenanger pellets. Has anyone seen a formula for boil time vs. IBUs for a pure-water hop extract? Trying to target 10 IBUs, but I don't know how to calculate alpha acid extraction in water instead of wort.
Or should I just get a Hop Shot syringe?

This says 1 mL gives 10 IBUs in 5 gallons of wort. As long as I'm making the EasyMac&Cheese, I might as well cut as many corners as possible!
edit: apparently the HopShot must still be boiled, which defeats the purpose. I have read of "pre-isomerized hop extract" but having trouble finding anyone online who sells it.
