That technique doesn't work, as most times, you end up unscrewing the chimney from the top cap (causing the glass to come loose and juice to pour out if it's still full). Remember, the Goliath has multiple sections. Chimney screws into the top cap locking in the glass, then the chimney base screws onto the deck/juice-flow control rings. Zephyrus you mentioned doesn't have juice flow control ring section. And no knurling is there to help you twist off the right section, as the v1 had. That section on the v1 that you could grab a hold of (and had no o-rings on the base to seal it/lock it essentially) would have made all the difference.
Trust me. Serious design flaw. Just now, I ended up unscrewing the chimney from the top cap and had to wash all the juice off the chimney (messed up my wicks too) so I could get a good hold on it, and twist the chimney hard enough to cause it to buckle the rest of the base (juice flow control pieces lock it into place). Even with my small hands, you just can't grip it. Even with latex gloves/freezing it, it's hit and mud on which section will actually unscrew.
What is clear is they are missing is a knurled juice flow control ring from the V1 so it's easier to grip. Check it out on reddit. I think it's mentioned on the review here too, from Bloke. All one could hope is they fixed the o-ring issue around the base because it's damn near impossible to work with quickly.
