Started with 148 grams of high quality shake and small bud.
Divided it into three quart jars (near filled all three).
Shake was chilled.
ISO came out of the freezer and I filled the first jar to the top.
Shook vigorously for about a minute and poured what I could into the second jar.
Got second jar mostly full of dripping solvent, and again shook for a minute.
Then into jar three. Still plenty of solvent to do the job.
After this last shake I drained off the solvent for filtration and distillation, yielding sample one.(on left)

All of the solvent saturated residual vegetation was dumped in a pan and set aside while sample one was attended to.
Results: Both washes yielded identical weight 7.5 gram concentrates.
15 grams total (10% return)

I had to gob some oil out in order to see any difference.
Left is first extraction and is more clear amber than the second wash, which still looks amber, but by comparison it looks green.
I am not experienced in evaluating vaping differences.
They both seem to vape the same, but the quick wash looks a bit better.
