Great question. In the process of making rosin, first you create Ice Water Hash to separate the trichome gland heads. Then there are typically 2 ways to process this Ice Water Hash:

1. Fresh press: The gland heads are put into a mesh pouch and then squeezed at high pressures and low heats. People will consume this fresh press without further processing.
2. Cold cure: Cold Cure rosin is fresh press that has been cured and whipped into a badder-y consistency.

You used the term “live resin” which is in a different realm than rosin. Resin = made with solvents. Rosin = solventless

• Distillate: While typically the most potent and used in vape carts, I’d generally say anything with distillate will be the least representative of the original material used (no taste), and something I try to avoid. Distillate = headaches, for me.
• Live / Cured Resin: Resin is extracted with solvents, and retains more of the plant’s profile of terpenes and flavonoids. A great budget concentrate option. This is typically where you’ll find shatters, waxes, budders/badders, crumble, sugar, etc.
• Live / Cured Rosin: Then we have Rosin which is extracted in a solventless method, and to me, is the best concentrate available. Full of flavor and character that is representative of the original plant/strain used. I’ve seen rosin come in shatter (fresh press), sauce, and badder-y variants.

I dab (vaporize) it on what’s called a “terp slurper.” Here’s a previous post of mine that shows the piece on the right: https://lemmy.world/post/913935

Dabbing concentrates is about heat control and retention. There are less cumbersome options, like Puffco’s line of products.
