Depending what you’re looking for you can make sift without freezing anything.
I prefer sift over hash which I rarely smoke, sift tastes like the bud/trim you get it from only more concentrated, its called live resin in some circles.
Fwiw after sifting I’ve washed trim to see what’s left behind…it isn’t a lot and even when gathered it’s not worth smoking…there might be pics in the link.
Terps are water soluble the process of washing ime removes a lot of the flavour that’s my primary reason for making sift over bubble sift being easier to make is a bonus.
