I bought one of those today while looking for something else. I'm a little puzzled over how I can make it work for my usual lattes, but I'm excited about the mechanics of it. I should be in for a real treat.
Thank you, Trius. About the "explosion" - what am I to expect? Do I leave the lid closed or do I need to monitor the flow?
Also, this moka pot is aluminum. Do I need to make a batch and throw it out in order to "prime" the pot?
Great questions!
The "explosion" is nothing to fear; Bialetti recommends to keep the lid open. I agree with this, as I think you get slightly better crema. It's never escaped the chamber even with the lid open.
As for seasoning the pot, yes, the first pot will not be very good, so I would use "junk" coffee that you don't care about. It's been awhile, but I think the moka was good on at least the 3rd pot, maybe even the 2nd.
Another thing -- don't use soap or detergent to clean the Brikka (or any aluminum moka pot) -- normally I just rinse and scrub with a nylon scrubby. Sometimes I polish up the exterior with a non-abrasive cleaner such as Bon Ami. I have even used Bon Ami on the boil pot interior. The boil pot, for some reason, doesn't dry well even when you put it in a dish drainer or on a counter top, mouth down. I haven't gotten to the stage of drying it out with a towel yet, but I probably should. Still and all, my moka/espresso tastes fine with only minimal care of the pot.
One thing I might recommend is to buy a repair/spares kits when you buy the Brikka. This is in case you do something stupid and the seals get shot. Not that I would have ever, in the fog of pre-coffee-morning, attempted to make espresso with no water ...
