There is an entire thread about making Budder at International Cannagraphic mag. Here is part of that thread:
"Here's a quick explanation (it's basically dried REALLY GOOD honey oil)
It takes BUDS to make budder of this quality with ISO, tops preferably, of a super-crystally strain (ones with lots of terpenes seem to do it well)
rinse #1
the product, frozen buds, previously pulled apart to individual nugs (each about marble size), are put into a 4 cup pyrex measuring cup (2/3 full), and frozen iso is poured into it (enough to cover the buds, stirred , and drained immediately into said sieve/filter setup (holding back the bud while letting alcohol drain)
rinse#2
again fill the measuring cup with (fresh) frozen iso over the same batch of buds, this time crunching a little bit of the bud, and again drain
rinse #3
again fill the measuring cup with (fresh) frozen iso over the same batch of buds, this time crunching them fairly well, and again drain
remember, keep your rinses seperate (i have 3 or 4 stations set up with sieves/filter ready so I don't have to wait or slow down, at the end you can decide @ what point the rinses are impotent, or have color, or taste bad, allowing you to maximize not just yield, but potency. (some of us custom tailor our rinses, #1 & #3 together, etc., as they all produce adifferent high.
this is what I consider 3 rinses.
Remember, this can easily produce a dark, poor tasting product, the process MUST be done extremely fast, all 3 rinses in 15- 30 seconds.
The key i found in success was allowing normally dry buds out for several days in a dry, warm environment, until they are light colored, and puff into dust when squeezed.
It should be that dry, get rid of as much of the chlorophyl before hand, and the extreme rinsing has that much less of a chance to pull it out.
this is also why everything is frozen, the iso has less of a chance to soak into the plant material, the coldness and dryness and the broken up state of the buds all help in allowing as much crystal to be washed off the plant as possible.
I found #1 rinse isn't as good as when U add #2 and sometimes #3 to it. there is something to that, as well as increased yield.
typical yield off 28 g. of excellent bud - 3.5 - 4 g. of budder, although I've seen up to 5 g. on some peoples weed (where are U now) Although most strains give less than 3, and plenty of so called killer strains won't even "budder up'. By this I mean the final step, when it dries into paste from a liquid state, and the color changes to very light, even white some strains, the crystal is so pure. adding the second rinse to 1 really helps. typically I would get 1.5 g. off #1, about the same off #2, and less than 1/2 of that off #3 (1/2 - 3/4 g.)
butane yields more, up to 50% more in some cases."
