i fully agree, with my results. i do a very long press at temps that wont cause an audible sizzle for around 45 seconds with no darkening of the extract, it comes out extremely light, and the long time allows a fairly thorough extraction without cooking it. i dont see a way to do higher temperature extractions that would give great yield and very close to 0 product damage like this does. it seems to me that a key to large extraction technique is to have the extract leach away from the press zone for sure, you need a system where the rosin collects outside the press zone primarily for large volume, with a hair press and no more than about 1.5 gram chunks, it seems the bud thickness and the fact it isnt an incredibly powerful press method, leave room for the small amount of extract to be collected within the press zone mostly, but since its a small amount and if you do it cool enough, it doesnt seem to damage it.
May I ask what temp you are using?
