so I'm still new to brewing with Brikka and I found my results are quite inconsistent. So, I try to follow each steps and the how to make coffee part on the product manual. Cold water, fill the funnel with ground coffee, etc. But what I've found is basically:
If I don't tamp (just a tiny bit, not hard at all, to level the coffee and remove empty spaces between), usually it doesn't work. It brews, let out a bit of coffee, but there's no the usual brikka sound and usually steam comes out from the valve. Being too paranoid, I usually turn it off and redo (I'm too scared it will explode or something), make a new cup.
But if I tamp a bit, more often the crema that comes out are too 'bubbly'.
I don't really understand why, can anyone enlighten me? Thanks a lot!
