Back in the 2003-2007 time in central California, I used to occasionally get a bag of great bud that smelt like old fashioned lye soap when smoked. It had that sharp, bar soap smell. Is that what you were reffering to with “soap haze.” It still is one of the most distinctive smells and smokes I’ve ever had. I’ve been chasing it for years.
I’ve extracted a strain called “NYPD” several times recently that has a great gas/sour profile.
