What's up update.
I keep playing kitchen chemist. Kicknitup and I keep "Searching for the Grail".
This is an email I sent a few days ago, less the personal stuff.

===================================
We are doing well for our age [;>).
I don’t pay as much attention to State news as I should. I do know that they finalized a rule that increased the maximum plant count that can be grown by the suppliers from 450 to 2500 plants.
And, I think that there will be a recreational bill introduced again this year. It probably will pass. I may be overly optimistic on that.
The way you are doing keif is close to what I am doing. I breakup the buds to about the size of rolling material. Then I dump it onto a 300um screen followed by a 150um screen, then add a few chunks of dry ice to each screen and shake it.
The last batch was from everything I could find around the house that was less than good buds, maybe two ounces of old buds and another 6 ounces of assorted trim. I alcohol extracted what went through the 300 and not the 150. It yielded about 20% of the starting weight. So, baking with it or saving up a quantity worth extracting would probably be what it is good for.
I have about 35 grams of the keif that went through both screens left. The next time I do an alcohol extract I will run at least some of it to see what it will yield.
I have reclaimed alcohol by modifying a cheap stainless pressure cooker and heating it in an oil bath. I was reclaiming about 80% but it takes a lot of time and is scary enough that I was never comfortable doing it.
There are small distillers on the market. The problem is they are for water, not alcohol. SweetSue found one that was for alcohol if I remember correctly.
I am refining an alcohol and dry ice method that is yielding better than 20% of non decarbed extract. So, THCA & CBDA plus a concentration of the terpenes and anything else. Though, it could be decarbed before or after extracting.
The idea is to keep everything well below the freezing point of water.
I start with ground and frozen buds in a beaker. I add dry ice, then I add enough frozen 190 proof to cover plus a little. It will boil rapidly for a while, then slow down as the alcohol cools to about -40F.
Stir for about 30 minutes. Add more dry ice as needed. Strain into a vacuum funnel, return the material and add more alcohol and dry ice. The material volume will be reduced and take less alcohol to cover. Then another 30 minutes with stirring. Strain, then I pour a little alcohol over the strained material to wash out more of the oil-bearing alcohol.
The first time I tried this method, I kept the two rounds of solvent separate for drying. The second batch was about 10 to 20% of the first and had very little color difference. This tells me that the second run is worthwhile but combining them for drying is fine.
I filtered the extract twice, then poured it into a Pyrex baking dish with one end elevated. Then I set a small fan to blow across it. I let it mostly dry (A day or two) then rinse and wipe down the sides and bottom of the dish with alcohol and pour off the extract into a small beaker until the dish is clean..ish. The extract can be air dried or heated to speed things up. I leave it in a 40 or 50ml beaker to dry and use. The only problem I have had is some pockets of water can form under the oil when it is in the dish. Tilting the dish and a little picking at the water will speed up drying.
The product dries to a very heavy oil at room temperature. It will stay on a dab tool and it takes about an hour for the tracks from scraping up dabs to relevel.
The batch that I did was a little less than 500ml of ground buds and can barley be done with one bottle of Everclear.
I seldom do the cherry read titanium hits any more. I tend to melt a dab on top of ground bud in a pipe or bong.
The high is noticeably different than say shatter. It is not as intense or hard hitting at first. The high comes on rather slowly for an extract. It builds up to a very intense, clear headed, rather long lasting high.
That is as far as I have taken the experiment. If you try it, let me know how it turns out.
