Hello! This is a slight amendment I have discovered since creating this thread that the best way to treat your abv is to do a butane extraction, and then dissolve that in ethanol (to extract the fats and waxes the butane extracted). filter and purge. this will leave you with oil that you will be just amazed with. the time and effort to make it is worth it! The taste and effect that this cbd/cbn rich concentrate has is very effective! especially when combined with something that has a standard, or regular thc dose to compliment it!
The experiment was fun and still a worthwhile read. enjoy.
ABV Oil Extraction experiment: QWiso vs Water cure with QWiso vs water cure iso in freezer vs bho vs water cured oz as bho.
Purpose:
To determine which method of extraction will perform the best regarding yield, taste, potency and overall final product
the 5 methods of extraction will be as follows:
1. Quick Wash iso extraction. 1 oz of abv, + iso in the freezer and a 30second shake and strain
2. An oz ran as bho normally
3. An oz water cured abv for a week with daily water changing + 5 days in the freezer iso extraction
4. An oz water cured abv for a week with daily water changing + Quick Wash iso extraction.
5. An oz water cured abv for a week with daily water changing + An oz ran as bho
Hypothesis:
-The batches that have not been water cured will have the largest yield, yet be less desirable quality wise.
-I think the BHO oil will be of better quality than the ISO.
I think the water cured iso will be better than the regular abv iso oil.
Materials:
-5 oz of abv
-3 mason jars to water cure and make ISOhash with
-1 bho/QWiso extraction kits: Plates, razor, vice grips lighter, butane, 99% isopropyl alcohol... Whatever you use normally will be fine.
-5 Vials to contain and weigh the final product
-scale (mine is only accurate to 0.1g)
-freezer
-hot tap water for water baths
Method:
Water cure preparation:
1. Shake container of abv to mix it all well together
2. Weigh out 3 one oz quantities of abv
3. Put abv into panty hose and tie them off
4. submerge in the mason jars with room temperature water. Once waterlogged top up with water and seal the mason jars up
5. Place in a dark location at room temperature
6. replace the water and rinse the jars after 24 hours. Repeat every day for the week
7. After 1 week drain and dry out the final product
8. and oven on the lowers heat setting done in 5 minute batches with turning and cooling seemed to work really well. The process took about 80 minutes
QWiso prep:
1. place ISO(99%) and abv(in mason jars) into freezer the day before extraction is to take place
2. pour in enough iso to cover all the abv in the jar and fasten on the lid
3. shake very vigorously for 30 seconds.
4. drain and filter.
5. evaporate and collect product
Long Soak prep:
1. Freeze the iso and abv with the other jars.
2. Pour in iso to the level of the abv and let it soak for the desired amount of time. I am going with 5 days because it was convenient timing wise
3. drain and filter
4. evaporate and collect product
BHO prep:
1. place abv/wc-abv into extraction tube and run as you would normally
2. once butane is running clear, stop running fuel and wait for final drips
3. evaporate and purge
4 collection
Observations:
Water cure process:
On days one, two and three of the Water cure the water was a very dark and smelled very strong. it was not a very pleasant smell either. I would describe it as an ammonia type smell
the colour intensity began to diminish. I can still see particulate floating in the water. there is sediment on the bottom of the jars and when I pick them up I disturb the water and they mix back up. I assume this is actually pieces of marijuana that are small enough to pass the mesh size of the panty hose. (This will attribute towards a degree of the loss when I weigh the "oz" again after drying.)
when I took the abv out of the panty hose "tea bags" I noticed the abv was markedly much more green than it was when I originally put it in a week ago.
I used the oven at the lowest setting (170F) and cooked it at 5 min intervals with stirring and cooling between each cook. It took about an hour and 20 minutes to get it all dry.After cooking it looked less green and more like black tea. It has noticeably lost it's golden brown colour that it started out with.
I re-weighed the 3 oz of abv i had water cured and they each lost about 34% of their original weight. (I was worried I had lost goodies from this process and yield would be reduced.)
* only performed 1 wash on all samples. this was because I didn't want to handle the materials again or waste iso and butane on them for such a small return.
Water cure BHO:
I was luckily enough able to fit the entire oz into the baster so I only had to do 1 run.
I was surprised at the level of brown green colour coming out when the butane first started running though the end of the tube. It nearly consumed the entire 300 ml can of butane in the process.
Amount produced: 0.6g
ABV BHO:
This had to be done in 2 runs, as it would not all fit in my tube in one go. This ran the more expected brown colour. Only required 1 can also even though 2 runs were done.
Amount produced: 0.5g
Water cure QWISO:
Purging took place in a hot water bath on the stove with the ventilation fan on max. I DO NOT recommend evaporating indoors. the purging after the alcohol has gone is fine. the process took 30 min
Amount produced: 0.5g
Water cure 5 days freezer iso soak:
Purging took place in a hot water bath on the stove with the ventilation fan on max. I DO NOT recommend evaporating indoors. the purging after the alcohol has gone is fine. the process took 30 min
Amount produced:0.8
ABV QWISO:
Purging took place in a hot water bath on the stove with the ventilation fan on max. I DO NOT recommend evaporating indoors. the purging after the alcohol has gone is fine. the process took 40 min. This is longer than the other ones because more iso was needed to cover the volume that the abv took up compared to water cured abv.
Amount produced: 0.5g
Picture: 1= BHO 2= W.C BHO 3= W.C QWISO 4= QWISO 5= W.C.ISO
Conclusions:
*the best type of reclaimed oil to make would seem to be the Water cured BHO oil for taste and getting a slight yield perk over standard non water cured runs (0.6 vs. 0.5 return). the water curing process did indeed improve the flavour and smoothness of the dabs.
Water curing your abv seems to increase the return in your yield with BHO, but not with QWISO. (No 5 day soak for regular abv was done to compare against the 0.8g return.)
Water cured abv soaked in iso for 5 days gave the largest amount with 0.8 grams of oil produced. The Water cured BHO method came in second at 0.6 grams
Water cured vs standard abv in a QWiso returned the same yield, however other methods that had been water cured did return higher than non water cured material (BHO)
taste testing initial thoughts and comments:
1. QWiso ABV: (0.5g)
- Classic Iso based hash oil taste, no real flavour to speak of
- More chunky than runny
- Smooth hitting
2. WC QWiso ABV
0.5g)
- Classic Iso based hash oil taste, no real flavour to speak of
- Smooth hitting
- thick but clearly fluid and not chunky
3. WC 5 day freezer soak (0.8g)
- Harsh
- Sparked on the Ti plate when doing the dab
- Described as tasting like "motor oil" , I would agree it was not pleasurable tasting.
- thicker than the other WC QWiso batch
4. BHO ABV: (0.5g)
- Dry and a little harsh with a strong oil flavour (slightly nutty)
- Notable different and no iso extracted taste to come with it.
- Didn't want to stick on a hot dabber
5. WC BHO ABV (0.6g)
- Best tasting, smoothest
- Didn't want to stick on a hot dabber
So rating them from best to worst we think
Best being 1st=5 , 2nd=4, 3rd/4th=1/2 and then 5th=3 as the worst.
Errors and comments:
It would have been nice to have used a scale with better accuracy because the 0.01g readings would be a little more interesting for comparison.
A 6th run should have been done with an oz done in a frozen iso soak for 5 days along side with the water cured batch. This would allow us to compare the yield of that fairly against the 0.8 gram that came from the water cured batch. I know it would be nasty and gross oil, which is why I didn't want to do it.
concern: personally, I have always questioned the water cure method because I have done ice water hash extractions before. I know the cold temp helps make the crystals break off more easily, but I think it still happens in water of any temperature. It happens in my jars and bags I get my buds in and that's just in the air. I was careful not to be too rough with the sacks of abv when changing the water. This so far seems not to be true. in the case of the BHO runs, the water cured batch out performed the regular abv bho run. I think more tests need to be repeated before we can definitively say these findings are solid. but they are what I have found so far.
I suggest you all do the comparisons you are interested in and report back to us with your findings too!
ABV info:
about 40% of the abv was made using a volcano of various "a" grade strains i could get my hands on (i only want the best herbs i can get) the rest is made from the ssv, mflb, pd probably in that order too.

Really impressed with your exacting technique. We need more people doing these kinds of basic science experiments to further our knowledge of the herb and its uses.
but i will do that for ya sure!
But after 12 hour cure the taste is only a fraction nasty of what it was..
