I am often in Stockholm, as my wife is Swedish and her family lives there. I read an article in a local paper about a coffee shop called Frapino that is supposed to be fantastic. Reading the attitude of the owner, Lakis Toutouzoglou, towards what makes a good coffee, they were certainly walking the walk, so I felt obligated to try it out. I was yet to have a good espresso in Stockholm, so I didn't want to get my hopes up!
I ordered a double espresso (they were using Yirgacheffe) They use a La Marzocco 3-group machine. They roast beans every Thursday. And they give you free wifi! It was a very nice, cosy place and I sat down to try my coffee.
First sip was a concern, thought it a little bitter, but it got superb as it cooled, very creamy tasting. Maybe it wasn't bitter, and I was just being fussy, so in order to be sure, I ordered a second!
I was being fussy, the second cup was, if anything, better than the first.
The owner trains his staff with the intention that the coffee will be excellent no matter who serves you.
If you're ever in Stockholm, visit Frapino. LÃ¥ngholmsgatan 3. The nearest underground (tunnelbana) is Hornstull.
