Ive noticed after a slab comes straight out of the oven when i sample it a lot of the time it tastes slightly different. like if its a tangie strain the tangie will become more noticeable after its been in packing for 24 hours or so. am i tripping or is there something that happens once the shatter is exposed to atmosphere? i havent really noticed a big difference in crumble or sugar, just shatter.
One thought. The monoterpenes would like to leave and migrate toward the surface in their escape efforts, where ostensibly the enrichment adds to the aromatics.
Yes. Concentrates cure just like flower. The terpenes evaporate over time within the has and leave THC-a crystals remaining. This is why shatter often turns to crumble when it isn't stored properly (in a cold, dry and dark place).
Not really. It's more about the temperature you hold it at. Think of it like organic butter or fresh unprocessed extra virgin olive oil. It will "go bad" at room temp fairly quickly because ultimately it is the oil from a plant and will begin to break down no matter what. It's best to keep your hash in an airtight container in the freezer.
