Post-Processing Rosin - Your wish, after the squish

[BabyFacedFinster]

Do you use filter bags? I personally do, but many are having GREAT success without.

Press slow, low temp, and run a little longer. Once your puck is in place, wait 45-60 seconds and let your material soak in the heat. Add pressure slow. I never feel like I am leaving anything desirable left in the puck when I get super quality gold.

Signs you are pressing too slow- you will budder on the plates during the press. While it is DELICIOUS, it is not desirable as it actually blocks flow and oil from escaping the puck.

My presses are typically 1 minute heat soak, 2 minutes of SLOWLY feeding pressure. At this point I am flowing before I hit any real resistance on the pump. I do have a gauge, and this is the point in when it registers. Then I continue feed pressure, even slow pumps for approximately 2 minutes, or until I hit my mark on the gauge (which varies dependent on puck size and if there is one or two pucks being pressed at a time).


Your yield will also likely lighten a good bit in color in the days following your press.

Great info! Thanks @FlyingLow

So you might be slowly adding pressure during the whole time your pressing? Do you ever let it sit after reaching max pressure?

I will do the longer heat soak. I have been adding presure by laying my hand on the handle and trying to feel the resistance and letting the weight of my arm lower the handle as the puck gives way. Near the end of my presses I am bearing down on it more.

I wonder how much efficiency I will lose?

If I do a press at 160-170 I get around 15% return, I will repress the puck again at 220 and get another 4-5% for a total of 19-20%. If I do just 1 press at 220 I get 19-20% so for me there is no real difference in total yield.
You will have to add pressure as the rosin leaves the puck it will get thinner. I usually see the pressure stop dropping at about 3 minutes after ramping up the pressure (the rosin bubbles have almost stopped at that stage too.)

I let it sit for a moment but but long. You will notice decreas ok NG flow at

Great info! Thanks @FlyingLow

Not for long at max pressure, perhaps 30 seconds or so as the bubbling over the edge trails off.
Easily nets 18-22% yields regularly and occasionally over 25%. Starting material is everything.

Enjoyed this. Especially the focus on Blue Dream. Even though my BD came from a medical dispensary, god knows these days if it is a true BD strain or maybe one of many phenotypes.

I tried warming my BD rosin in the jar until it became runny. (Those 5ml thick bottomed glass jars fit perfectly on top of an e-nano). I began whipping it up with a dab tool until it started to thicken up again. It started to get all shiny, the way melted sugar might look if you let it start to cool and began pulling it like a taffy. I hoped I was on my way to a new consistency, but when it cooled it just returned to the same rock hard shatter. Back to the drawing board.

 

[Sick Vape]

I always thought you needed more rosin to try to extract thc-a.
I wonder what he did with the "sauce" part.
So if I listened correctly he represses the same bag at several temps. 100°F, 110°F, 120°F each time for 10 minutes or so.

I never tried that collection tool.
I have one of these on order as my latest instrument of frustration,
https://www.fasttech.com/product/9694246

If they are any good I will get a few of them.

Grabbed two of these as they were so cheap (just like me), thank you sir! I also got one of the Style C “Prison Shank” because you know, my village streets are pretty mean and tough. Went for the free 30 day slow boat shipping because I have more time than money...

 

[LesPlenty]

Yep, best collection tool yet, I now have 2 of them but could have got away with one as my SJK IH is now sitting next to my press and a quick heat in there and the last of the rosin wipes easily onto the silicon mat for rolling into a ball or sausage and dropping into a container.

haha after seeing @pxl_jockey posting this ... I also bought one of this and another one... hope it will make collecting rosin much easier, more efficient...

what is SJK IH (induction heater?) please tell us more about this and your technique...

 

[LesPlenty]

Yes, an induction heater that the above collection tool fits into. I will take pics next press to show my method.

Haha you started a wave. I got two too, after your recommendation and I love them too.
I have no IH yet, I just scrape the tool clean with a small knife or when very liquid just smeared it onto some PTFE foil.
I got two other models that looked interesting to me, but I never use them.

What the hell, I just bought one too. Always looking to streamline the collection process.

I don't have an IH, but I hold my gunky dab tool over my e-nano heater for a few seconds and it cleans right off.

 

[LesPlenty]

I prefer the IH heating as it heats the metal more than the rosin, straight in .5 second heat then the last smear just wipes off easily onto the collection mat.
I think this tool is so good due to the rounded finish on the wedge, you can go hell for leather on the paper and it will not tear(as long, as you hold the parchment paper taught enough).

So i have had my herb in vacuum sealed mason jars with a boveda 62% for months. 2 out of the 3 press sappy and one strain turned out really good.

My question is, is it really the moiature thats an issue? Everybody says moisture is the culprit but my nugs are right at 62%. The sappy material has been air drying the past 4 days and is still too runny to mess with.

What do i do?

You just need something cold and conductive to facilitate the collection of rosin. Put a thick flat piece of metal in the freezer for a few hours until nicely chilled, then put your parchment sheet on that metal plate and your rosin should now be cold enough to collect easily enough. I suggest storing in glass jars only, especially for anything sappy.

When it comes to flower rosin a number of variables can create a sappy, difficult to collect consistency including terpene content, residual moisture, partial decarboxylation, and so on.

Thank you for your help. I was able collect all of the rosin this way. After letting it sit awhile do you think it will get easier to manage?

These were my first presses ever. I noticed the sappy stuff taste was a bit off and was wondering if that was moisture boiling the oil and tainting it while vaping. Taste reminds me of some RSO I made and tried to vape. It too had some moister left over from the grain alcohol.

 

[LesPlenty]

I found if I lowered the pressure (800psi oer square inch on puck) and temperature (75c\176f) with my 18-month-old buds it would stop the oily stuff.
Cold helps to stop the runs as mentioned (I just put my parchment in the freezer to help collect but I think the rosin may have absorbed moisture as I got a little hissing on the nail from memory).

 

[invertedisdead]

Once the rosin is in a jar the sappy consistency shouldn't matter much, if anything it just makes it easier to grab a dab as you can simply "dip" your tool in the rosin.

Depending on why it came out sappy, it could change consistencies over time to something more stable but it just depends.

noticed the sappy stuff taste was a bit off

What vaporizer are you using? Flower rosin tends to like lower temperatures. It's very possible you used excessive pressure and squeezed some plant juices into the oil which can definitely affect taste - pretty much every beginner uses too much pressure at first, easily remedied with a bit more experience pressing.

 

[Vape_Or_Die420]

I am using the Linx Hypnos Zero on the lower settings.

Likely i did over press. With the nugsmasher mini. It will take some user error to figure out what pressure works and what doesnt. Thanks!

Ive started to look for less terpy buds on purpose now, and will going back to growing oldschool hash plant / g13, Seems to be getting allergic reactions to super high terp strains especially when pressed into rosin,

Im all good when smoking a less terpy strain like g13 ( This batch of herb pretty much turned into shatter and had very little taste while dabbing ) However this is the only stuff around that isnt giving me a straight headache these days...


Press terpy herb at super high temps for less terp content? Or will i just create popcorn tasting sabby mess?

I would rather try heating your rosin after the press to remove terpenes to avoid popcorn taste!
You definitely will not have more popcorn taste that way, than when you press the flower with super high temps. I think.

Basically you could raise temp gradually. Maybe there is a temperature that releases more of the terpene you cannot tolerate. When the temp is high enough for most of your "bad" terpene to have evaporated your treated rosin should be more tolerable for you. In theory!
It maybe could help you identify the bad terpene.
In practice you would have to stir alot to be able to evaporate most terpenes out of that sappy liquid.

 

[LesPlenty]

@MegaMan2k The video above that @Sick Vape posted shows a guy making THC-a diamonds from rosin by removing the sauce content, you could try that, you would not have to remove all the sauce, just enough to help your situation...worth a try?

I just picked up an eighth of Hash plant myself. I will press it in the future, but for now I've put some flower through a vapcap. It has a pleasant earthy flavor which is not overpowering so I can see the lower terp profile. I was hoping that between the flower and the rosin I might get that flavor I remember as a college student when I obtained a chunk of black hash. It looked like half a Chunky bar, minus the raisins.

I agree with trying a post press warming/heating of the rosin, over pressing at a higher temp. I have tried heating rosin at 150F on my press plates for several hours, and also just resting the jar on top of my e-nano set at a 6 (which is most probably too hot). My goal was to change the rosin consistency, but results have been inconsistent. Regardless, there have been times when I noticed a decrease in flavor over time. Unfortunately, there have been times when I've also noticed a reduction in potency at the higher temps. I can't offer a solution, but wanted to at least report out on some observations. It might be worth exploring.

 

[Sick Vape]

Interesting. I think your findings fit the picture and broaden it a bit. I like reading about them.

I believe you can obtain alot of the traditional hash tastes by (un)correct storing.
There is a book somewhere from one of the sons of ben dronkers, where he describes a method of storing trichome heads at certain temperatures to get the traditional hash tastes.

I myself forgot about a dab of some cbd rosin for a couple of month. It filled up my room with a perfect black hash smell when dabbed. It smelled completely different when freshly pressed. I had no idea it smelled like perfect black hash then.

You might find this blog post interesting, it discusses the terpene "Hashishene"
