For e liquids 70/30 pg to vg ratio seems to work. Add 7% everclear pure grain alcohol. it sands off the higher notes in the flavor profiles. Most flavors do best in the 15-20% range. E Cig forums will direct you to calculators to make flavors.The Perfumers Apprentice sells good flavors. For vaping cannabis I use all vg and the alcohol is 7% but I use green dragon concoction. Fill canning jars with good weed and top off with vg. Pressure cook at 250 for 30 minutes. Use a tank ecig system and vape anywhere anytime. Essential Depot sells PG VG. PG tastes like shit. But it works for eliquids. Food industry puts PG into everything. It enhances flavor but doesn't taste good by itself.

Since vaping does not achieve high temperatures pressure cooking decarboxylates the THCV and it makes the trichomes weak and sluff off their attatchment points on the leaf.VG tinctures taste pretty good I think. PG works good with nicotine, and even 0 nic e liquids benefit from PG as a flavor enhancer but it is useless in tincture. And Essential Depot VG is non GMO, lab and food quality, other companies are probably just as good. By using a green dragon type mix as your alcohol component you are bumping up the available trichomes in the tincture without going through the trouble of making BHO or some other concentrate.
Here is a 10 ml bottle taken off my recipe calculator: 70-30 PG VG 7% alcohol-19% flavor-
PG= 4.89 ml or 161 drops
Alcohol= 7 drops
VG=3.00 ml or 99 drops
Flavor=!9% or 63 drops
In your recipe you can equally divide the flavor component or give one an advantage. Caramel vanilla sounds right at 50/50, maybe lean more vanilla. Also you should buy some "cotton candy" flavor. It is methyl alto and is used to give a touch of sweetnesss and flavor buffering. 1 or two drops /10ml is enough. Almost all e liquids contain cotton candy.

Krunch, We have been doing e cig vapes for a while now. They are the coolest
fucking thing since sliced bread. You can hit it anywhere in public, even in
non med states. We have sat at the beach bar right next to folks all of us vaping.
You need to make a glycerin tincture and infuse it with concentrates. I just take
bud and decarboxylize it, then put in canning jars and cover with vegetable
glycerin. You have to let the glycerin sit for a while to get the trichomes to
slough off. When you actually make the vape liquid it helps to cut the glycerin
with alcohol because glycerin is so thick. I make green dragon and cut the VG
with that. At the end of the process you add your concentrate. You could bypass
the whole process by just adding concentrate to VG. You could make gallons easy.
I buy VG 2 gallons at a time for 50 bucks from Essential Depot.com. Food grade
Kosher. Enjoy. This is the future of medicating, no doubt.

cool. i will add you recipe into my list and hold onto your method, might just use it. sounds safer than a double boiler and exposed alcohol method. sounds quicker than a 90-120 cold process decarboxylation.

so does the alcohol go in before you started to pressure cook or after.

i got this method from krunch's thread on this site. he adds flavoring and alcohol after decarboxylation. so just to confirm all your stuff goes in the jar prior to pressure cooking, correct?

To make a batch (2 bottles), start with one ounce of high quality dried and cured
trim. Do a quick 20 second wash with 99+% isopropanol, strain and filter, and
evaporate the iso to get the golden colored oil. Purge by dissolving in Everclear 190
and evaporating. I do this 3 times per batch, although I don't know if that's really
needed. After purging, dissolve in 50 mL Everclear 190, filter again, and you're done.
The result is a beautiful golden colored tincture.

I do a second extraction on the same trim, this time with room temperature iso for
24 hours. Repeat the same process as with the first extraction, and you get a darker
colored tincture that's still very strong. I haven't done enough experimenting yet
to notice a difference in effects between the tincture from the first wash vs. the second.

The trim still has some good stuff left after both extractions. Simmer a few grams
in a cup of whole milk for 15 minutes, strain, and add cocoa powder and sweetener
(or chocolate syrup) for a nice relaxing beverage.

The colors I got here are interesting. I grew C99 and Swiss Cheese last fall at the
same time. They both got the same organic soil mix (peat, coco, perlite, worm castings,
blood meal, bone meal, lime). The Swiss Cheese used up the nutes faster, so the trim
was mostly yellow by harvest time. The C99 still had some green trim. The second iso
wash with the C99 trim came out a lot greener than the Swiss Cheese.

Glycerin is a concentrate that most people stay away from because of the belief
that it does not work, it is not strong enough, or any other random myth.

The truth is...glycerin DOES work. Let me explain how I do it...then you take
whatever you learn from me and put it to the test. I cannot guarantee success
your FIRST time around, however, you will get good at it!!


1. Start with 100% PURE Kosher food-grade vegetable glycerin.

TO MAKE WITH HASH or HASH OIL...You can add many different forms of THC to the
mix; however, hash and hash oil cannot just go directly into the glycerin!!
You have to DISSOLVE the hash/hash oil prior to adding it to the glycerin.
This can be VERY tricky.

You would need EVERCLEAR. In California, Everclear is only 151 proof alcohol;
however, in NY or NV...you can get Everclear that is 190 proof...MUCH smarter
to have higher proof!!

WEAR GOGGLES and do this next step in a WELL VENTILATED AREA. BE VERY CAREFUL
as this step is volatile. Do NOT use a gas flame...ONLY use induction/electric
burners.


Make a "double boiler" setup...essentially, you need a med-large pot and a
large glass mason jar. For every gram of hash/hash oil, use at least 2 oz grain
alcohol. Add the alcohol to the mason jar first...fill the pot with enough water
so that when you put the mason jar in the pot, the water comes up at least
2/3rds of the level which the alcohol is at in the mason jar. Heat the water/pot
carefully with the mason jar/alcohol sitting in the center of the water/pot.
USE A CANDY thermometer...let it sit in the alcohol...until it reads roughly
140-160 degrees. DO NOT let the temperature pass this mark...VERY IMPORTANT!!

Add your hash/hash oil to the warming alcohol and MIX with a HIGH TEMPERATURE
Silicon spoon (very important to own...will not let the hash stick to it...and
will not burn). You need to ensure that there is ENOUGH warm alcohol in the jar
to dissolve the hash/hash oil properly; however, DO NOT fill the jar past
halfway. Do this in BATCHES if you need to make more than half a mason jar
worth of hash/hash oil solution.

Once the hash/hash oil has dissolved, you can take this a step further and
SLOWLY but SURELY let the alcohol fumes steep out of the jar and allow the
mix to CONCENTRATE down to a lesser amount. Be sure to take the jar OUT of
the pot of hot water if the alcohol temperature goes above 160 degrees. You
should remove the concentrate as soon as it becomes MILKY in color and
consistency...VERY IMPORTANT that you do not go past this mark...as the mix
will become almost impossible to work with; sticky residue, hardens fast,
etc...BAD NEWS BEARS .

Once you have removed the milky concentrate...immediately transfer the hash
liquid to another mason jar filled with your GLYCERIN. NOW...depending upon
how much hash/hash oil you used, you must determine the amount of glycerin
to use. This is up to experimentation...you must decide how strong you want
it!! I recommend starting with 1 GRAM hash/hash oil to 3 liquid ounces of
glycerin...it will be strong.

Mix the glycerin and hash concentrate in the jar WELL with a wooden skewer
(I use a skewer because it mixes fine particles well and does not end up
with a mass of sticky glycerin on it...just wipe it off into the jar and
you are done). After mixing this up...seal the jar LOOSELY. WRAP the jar
with something BLACK/DARK...I use black latex gloves...just wrap one
around the jar up to the lid. You are basically protecting the mixture
from LIGHT...which is VERY damaging to this process. After you have done
this...next step is straightforward. Allow this jar to sit in direct and
indirect sunlight for the next 3-4 days (or more depending upon your
experimentation with specific types of hash). Make sure you check the
lid...unscrew it gently from time to time to allow for any escape of
pressure. Alcohol under pressure is dangerous...when heat is added, it
is volatile; however, you are not using much alcohol, mostly glycerin.
STILL BE CAREFUL...you know that.

Once the time has passed...transfer the product to dropper vials/jars
or whatever you wish to contain the glycerin in. Keep in the FRIDGE to
prolong its shelflife. Glycerin lasts A LONG TIME if kept properly out
of light/heat...so you should have a concentrate to last!!

You can add this stuff to hot/cold drinks and it will do the job everytime.

2. TO MAKE GLYCERIN with THC product OTHER THAN hash...

Use any one of your favorite strains. Most people would say "dont
waste the good stuff and only use the stems/seeds"...I use ALL of the
herb. That is my preference because I cannot smoke...PLUS, the end
result is powerfully potent!!

You can do this TWO ways. You can follow the SAME steps as outlined
above with the hash/hash oil...OR...the simple...but time consuming
method.

For EITHER method, you need to DECARBOXILIZE your cannabis. This is a
process that converts INACTIVE THCA to ACTIVE THC. Without doing this
first, your herb is serving NO PURPOSE.

You can decarb many ways; however, I recommend using a food dehydrator.
I bought one at a ROSS store for less than $20. Get one with or without
a built in fan. Place your buds on parchment paper on top of a shallow
bowl/plate. Place this plate of herb in the dehydrator and leave in there
for at least 30 minutes. Proper decarbing is done at a relatively low
temperature for long stretches. You can decarb in the microwave or
oven; however, you will NOT maximize the conversion of THCA to THC. The
food dehydrator will keep your buds at the perfect temperature zone
(140-160). Once the buds are dried and break up with a bit of crisp,
they are PERFECT. You are basically trying to remove ALL moisture in
this process as well as convert to THC.

In a spice grinder (use one SOLELY for your cannabis), grind the
decarboxilated herb to a fine powder.

If you use the alcohol method listed above...

You will be adding your POWDERED herb to the warmed alcohol. I recommend
using about 1 GRAM herb per every 1-2 ounces of grain alcohol. Follow the
same steps as with the hash...keep temp at 140-160...try to let the
alcohol cook off and concentrate the mixture down...but do not let it
get pasty or sticky. IF that does happen...NO WORRIES; just add a bit
more alcohol, dissolve the stickiness and remove the jar from the pot
of water.

Add this herb-alcohol mix to your glycerin in small mason jar, screw on lid,
wrap with something dark, let sit in sunlight for 3-4 days (or more).
Once this is done, you need to STRAIN out the herb from the glycerin.

Use a glass bowl or large jar, a stainless steel strainer...lined with
VERY fine cheesecloth. You need to strain the glycerin through the cheesecloth
covered strainer into the glass bowl/jar underneath to catch the mix.
Use a high temp silicone spoon to PRESS the strained powedered herb to
get ALL the glycerin out!!

DO NOT throw out the strained herb. You can try to make a SECONDARY
glycerin concentrate with this mix...just add it to another small jar of
fresh glycerin...let sit covered in sunlight for another stretch...and
strain again!! This second mix may not be as strong or even have any strength
at all; however, there is not point wasting the mix, right?

THE SECOND and simple way of doing this mix with your powdered herb...

Mix the herb into a small mason jar of your measured amount of glycerin.
Use a wooden skewer and MIX this VERY WELL until the glycerin is basically
a very light/fluid yet pasty consistency...it will be SUPER dark green and
look mighty fine!! Follow the same steps to seal jar and wrap in black...

Place the jar in a well lit area (window...porch; if you dont have sneaky
or suspicious neighbors, etc)...allow to sit in sunlight for at least 4-5
days (or more depending upon experimentation). Once done...strain out and
make another batch with that strained leftovers.

SHOULD THAT SECOND METHOD FAIL TO WORK OUT...you can resort to simply
WARMING the glycerin on an electric stovetop (LOW HEAT...no more than 160
degrees...use candy thermometer) WITH the powdered herb added to it. Warm
this mix for a good hour or so. There is NO NEED to warm in a crock pot
all day...it is too long and too hot...even on the lowest of settings.
Simply put...JUST KEEP A CLOSE WATCH OVER any of the methods you choose
to follow!!

You WILL have success!!

I produce medicated sodas for various collectives in NorCal...all
natural/organic sodas using fine strains...great stuff!! I always use
concentrate glycerin; however, I also use concentrate HONEY.

You can make HASH HONEY simply by following ALL the same steps as making
the glycerin with hash/hash oil...just replace the glycerin with honey.
SIMPLE!!

I wish you the best....PLEASE contact me should you run into any
questions/concerns/problems...and ESPECIALLY if you manage to make
a KILLER concentrate!! I hope you do

Hi ya'll. Looks like I noticed this thread a little late, but I haven't been
monitoring the medibles thread for awhile.

A lot of the key points have already been covered, but just a few thoughts.

Glycerin will only dissolve about 33% as much cannabis oil as alcohol. Is three
drops instead of one an issue for you?

Besides being a complex sugar alcohol that digests slowly and doesn't spike some
diabetics blood sugar, it makes a damn tasty tincture, sort of reminding me of
the flavor of wild honey.

As has been noted, some of the things in the hash oil are not all that tasty,
nor is the lingering after taste. Many of them are turpeens and flavoids, which
are all aromatic hydrocarbon chain oils, that used at the correct concentration
are delightful, but used heavy handedly can be just too, too, much and even bitter.

One thing that adds to the bitterness is chlorophyll and in heavy concentration
can be seriously upsetting to some patient's digestive tracts, producing cramps.
Chlorophyll is water soluble, as are plant alkaloids in the stems.

Using plant material, I use a couple of different processes to make glycerin
tincture and out of bubble or dry sieve, I use another.

For the first two processes using plant material, I use only bud or sweet trim.
Despite the fact that you can get oil from fan leaves, it isn't as tasty and
so I save them for making topicals.

Water is our enemy and even well cured plant material still has 12 to 15% moisture
content. Whether glycerin is polar, or not, it acts like it is and will pick
up the water soluble flavors from the water,

I first spread the material on a cookie sheet and place it in a 200F oven until
it is just frangible when I roll it between my finger and thumb. I then run it
through a pasta strainer to break it into smaller particles and remove the leaf
stems, which have bitter alkaloids in them.

Some people use a food processor for this, but I do not because it makes a
bunch of fines that are hard to filter out and chops in the bitter stems.

I throw the stems in bag and periodically we make stem oil topical out of them.

Here decisions are necessary about taste and quality or potency. The absolutely
best tasting glycerin tincture comes from the cold process, where you take the
material you just dried and seal it in a jar of glycerin in a cool dry place for
90/120 days. Periodically shaking it.

Run it through a 160/200 thread count bag in a tincture press, and it will produce
an amber product with provocative flavors that dart in all directions at the same
time, like wild honey from a panoply of different blossoms produce.

I have sped up the cycle some using a vibratory ammunition case polisher to shake
three half pints at a time and produced a reasonably good tincture vibrating once
a day for thirty minutes for one week.

Notice that we didn't decarboxylate first, because it adds its own nutty roasted
flavor and you don't have to, if you have time to set it on the shelf and let it
decarboxylate naturally. It will be this side of heaven tasty, but it won't be as
potent as the hot process and takes a while to mature.

For the hot process, I place material while it is still warm from the oven in a
mason jar to about the 2/3rd full level. I then pour glycerin in on top while stirring
to eliminate dry spots and top it off with about an inch of glycerin beyond that.

I set that in a hot oil pot set at about 200F, and stir the jar contents regularly
until it approaches 160F and then throttled back to hold 160 F for thirty minutes
while stirring four our five times.

At that point, take it out of the oil and set it aside to cool. As soon as it is
cooled (or the next day), place it back in the oil and again bring it back up to
160F while stirring four or five times. As soon as it reaches 160F again, I remove
and cool it again, and continue that until I have seven or so cycles on it.

The last time that I bring it up to temperature, I pour it into the tincture
bag hot and squeeze it hot.

You can also use that tincture as the glycerin to start a new batch and build
up the potency higher than anything you can do with one cycle.

The hot cycle is also flavorful, but more like a soup of well blended flavors
than individual flavors.

The last step is to finish decarboxylating the mixture. I say finish, because
it is the sum total of the time at temperature we have to consider. If I want
speedier meds, I need about 30 minutes at 250F and if I want sleep meds, I want
a lower temperature and longer time, like 225F for one hour.

As far as flavoring, I do that afterwards. I toss dried cherries, dried blueberries,
gari, and 190 proof into a blender and puree it. I add a touch of almond extract
and then cook the mixture in a hot oil bath while stirring, until the alcohol
is all gone.

After pressing a batch of hot glycerin, I add a dollop of the above concentrate
to the jar and bring it back up to 160F one more time while stirring and hold
it for thirty more minutes.

I then press the glycerin again and immediately eat the fruit from the bag. Hee, hee, hee...........

Hope that gives you some ideas!

Krunch, We have been doing e cig vapes for a while now. They are the coolest
fucking thing since sliced bread. You can hit it anywhere in public, even in
non med states. We have sat at the beach bar right next to folks all of us vaping.
You need to make a glycerin tincture and infuse it with concentrates. I just take
bud and decarboxylize it, then put in canning jars and cover with vegetable
glycerin. You have to let the glycerin sit for a while to get the trichomes to
slough off. When you actually make the vape liquid it helps to cut the glycerin
with alcohol because glycerin is so thick. I make green dragon and cut the VG
with that. At the end of the process you add your concentrate. You could bypass
the whole process by just adding concentrate to VG. You could make gallons easy.
