It's definitely CO2 extracted. It taste like most bubble hash or heat-extracted honey oil I've had in the past. It's a very generic taste, no sign of terps unfortunately.
CO2 extractions naturally have a lower terpene content because terps are water soluble and water is seen as a bad thing in CO2 extractions. For this reason, CO2 waxes are generally tasteless and for THAT reason, terpenes are often re-introduced (at least I think it's popular in California?) to the product after it's made.
All CO2 oil and wax I have had to date are tasteless. The terps are shot and have not been re-introduced as many places in CA do. I'm actually very interested in trying some of Cali's CO2 terp waxes. They sound fun, I mean who wouldn't want to make their wax taste like any terp they want?
You are right that it's easier to get the liquid consistency with something like a QWISO, but I've seen BHO that is hard as a rock to stuff that looks like diarrhea (I know, gross but usually BHO with liquid consistency is pretty bad news).
The batch with over 2% CBD is the one that has the higher THC content of 60%. Both batches cost the same though, so that was a little weird.
