I agree. This is a wonderful beer. I had it when I was in Budapest and again when I was in Berlin. I was ecstatic when I found it in Toronto, but I've yet to find it in the States. So - as a homebrewer, I figured I must clone it. You are correct though, it is served with nitrogen / beer gas, so you won't have that affect. However, I keg all my beers now and I have a "Creamer" faucet, so while it doesn't last like it would with beer gas, you do get the waterfall visual. Just don't blink, because it will be gone :-) What you're left with, using this type of faucet is a nice thick creamy head at the top. I have my CO2 set to 12 lbs and let it carb for two weeks. It's at the top of my re-brew list. Of the five faucets I have, I've decided this is a a brew I will always have on tap.
