Rosin: The clean, quick, and easy way to make concentrate

You may have heard of the latest trend in cannabis concentrates called Rosin. Rosin utilizes the process of heat pressing cannabis flower, hash, or even kief and collecting the essential oil that is forced out of the original product. What you’re left with is a pure cannabis oil, with all its original terpenes, that will satisfy even the most hardcore dabbers. Unlike BHO (butane hash oil), however, Rosin doesn’t require the use of harmful solvents, only heat and pressure.

Another benefit of Rosin is how easy, cheap, and safe it is to make compared to other concentrate production methods. Lab equipment required to properly make CO2 concentrates or BHO can run into the thousands of dollars. To make Rosin, all you need is a $20 hair straightener and some parchment paper or Oil Slick Sheets (NOT wax paper). The wider the plates are on the straightener, the better (2″ wide preferably). Some folks producing larger quantities of Rosin have rigged up T-shirt presses to achieve higher efficiency. If you are willing to spend some cash, ‘D-nail’ actually sells a pre-rigged press with heating plates on both sides and digital temp gauges.

For processing flower, simply fold a piece of parchment around a small bud(s). Allow your hair straightener to heat up to between 150-300 degrees Fahrenheit. There are varying opinions on the best amount of heat. More heat will yield more rosin, but will also run the risk of cannabinoid degradation and result in a darker product. A straightener with a digital temperature readout is preferable but not required. Some folks are able to feel the straightener with their finger and make a judgment call on the temperature. This may require some experimentation. If you want to get really precise, you can use an infrared thermometer on the hot plates of the straightener to really dial in the desired temperature.

pressing head onWhen you’re ready, firmly press the straightener over the parchment paper with your flower in it. The harder you press, the more Rosin you’ll be able to squeeze out. Some have had success using a vice to add even more pressure to the straightener (The strength of the straightener may vary). Typically you don’t want to press longer than about 5-8 seconds at a time. The higher the heat, the shorter amount of time you need to press. If you hear a sizzle, you’re pressing too hard or it’s too hot. You can press the same bud a few times leaving some cool off time between presses. I like to move the bud to a clean piece of the parchment for each new press so I don’t keep heating the extracted rosin.

In your parchment paper you should now see some Rosin that will now be separated into a lightly scattered silhouette around the bud. Use a dabber tool, razor, or card of some kind to collect the Rosin. If it’s too goopy to collect, a few seconds in the freezer can help. Lower grade flower will naturally yield less than top shelf buds.

Have some lower grade hash lying rosin bigaround? You can turn it into a much nicer product using the same technique except this time you’ll want to use a ‘pressing screen’, which are usually sold in 25 micron, as a filter between the hash and the parchment. Put the hash into the center of the screen and twist the screen tightly around the hash. Then fold the parchment around the screen and proceed to press. You may have to adjust the heat when pressing different products. You may lose a bit of yield to the screen itself but it’s a small price to pay to potentially transform a mediocre product into a top-shelf dabbable concentrate.

There are several different approaches to creating Rosin but they all consist of the same heat press concept. Try some different techniques and see what works best for you!

Lazy Chai

As I searched the internets for a tasty Cannabis Chai recipe to share with our members, I found quite a few elaborate and fun-sounding recipes, which I will include below if you’re the type to enjoy that sort of thing. As for myself, I prefer the easiest possible method for achieving acceptable results, hence Lazy Chai. This recipe serves four:

Ingredients:

1c heavy cream
6 bags Vanilla Chai (I used Bigelow’s)
.5g Blackberry cobbler (or some other form of hash or kief)

Equipment:

double boiler (I used a pan and a random metal bowl I found, you don’t have to get fancy)
whisk for stirring (or whatever, that’s just what I used, and it worked well)

Before you get the cream going, bring 32oz of water to boil and begin steeping your tea. It’s meant to be a bit on the strong side, as you will be adding a lot of milk and perhaps ice, later on.

While the tea is steeping and making your kitchen smell amazing, heat the milk in the double boiler, sprinkling the hash or kief over the top as it warms up. I avoided boiling the milk, and just kept it at a constant almost-boil for the next 20 minutes, stirring more or less constantly. As the cream reduces, add water so you don’t end up with a milk-based sludge product at the end. I ended up adding about a half cup during the simmering process.

I combined the milk/hash and the tea in a mason jar and utilized my colleagues as test subjects. Everyone loved the taste, and the hungry amongst us reported near-instantaneous feelings of relaxation with a sustained high that’s still going several hours later. No one’s yet had a full serving, but I’ve chilled the remainder and will try this evening; I’ll let you know how that goes :).

All in all, I’m very satisfied with how this recipe came out, and especially pleased with how easy it was to achieve some very tasty, effective results.

Now, for the more culinary-inclined (or the less lazy), here’s an alternative: A delicious-sounding recipe that I found in my travels, discovered in a comment on a very old blog

Cannabis (2 or 3 g)
2 Cinnamon sticks
2 cups water
1 cup milk (or soy milk)
small dash of nutmeg
5 whole cloves
5 tbsp. of honey
2 tsp. Ginger powder
a very small dash of white pepper

Bring water to a boil in a small pot and put in all ingredients except cannabis and milk. Let boil with ingredients for about 5 minutes, then lower heat to simmer and add cannabis. Let steep for 10 minutes on simmer and add milk, then enjoy. You can microwave milk for 15 seconds for better results.

The Firecracker Experiments: ABV Weed

Here at Sespe, we like to be frugal. Medicine is expensive, and we never waste a bit of it if we can help it. To this end, we have undertaken some experiments here in the Test Kitchen, using previously-vaporized materials to create some interesting edibles. There are many ways to make firecrackers, which are one of the easiest edibles possible, though definitely not for the fussy gourmet palate.

The science behind firecrackers is that an oily substance (butter, oil, or in this case, peanut butter) will extract the THC and other medicines from the leaves, and convert them to something you can absorb through your gastrointestinal tract. Peanut butter is also an ideal ingredient for its strong taste, which helps mask the fact that, let’s face it, ABV (already-been-vaped) weed is not delicious. I’ve read that baking firecrackers is not strictly necessary, that peanut butter itself will extract the medicine if left to sit long enough, but who likes to wait that long?

The ingredient list is simple: cinnamon graham crackers, oily (“old-fashioned”) peanut butter, and your vaped remains (variations on this recipe to be covered in future installments). I used slightly more than 1g vaped material per cracker sandwich, which I believe is a little on the high side as far as most recipes recommend. Now I understand the reason recipes don’t recommend using this much — it’s truly surprising how effective this “used up” medicine is.

So, the preparation: mix peanut butter and ABV weed well, spread on the sugary side of cinnamon grahams. Might want to consider adding just a touch of agave syrup for sweetness. Arrange into sandwiches, wrap loosely in aluminum foil. Bake around 30 minutes at around 325 degrees. About halfway through you’ll starts smelling good things — very encouraging! The result is a little on the dry side, but remarkably non-awful tasting. As for the medicinal effects, let’s just say I’m having a wonderful afternoon and I’m really appreciating my hair.
