I have been exchanging emails with Barry at Roastmasters and things have been going very well between us. He has offered me a refund and has also spoken with Joe Behm about this problem, which sounds fixable. Apparently the lid on some of the early models can cause a vapor lock, which leads to the incomplete brewing. Joe offered to send me a new lid and I have accepted this offer to see if it solves the problem.
Just curious if you received the new lid yet? I saw Joe tweeted that he had some minor surgery this week so he might be a bit slow to respond. I've got a Brazen from the original shipment but have not yet had a problem with vapor lock. Hoping I don't but would love to hear if the new lid is working.
