Just don't start a "My beer's not carbed yet" or "My beer taste funny thread," because then we'll tell you to wait at least two more weeks. And that there is nothing wrong. Since 3 weeks @ 70 degrees is the minimum it takes for an average gravity beer to carb and condition, despite what the munton's instructions say. Just like kit recipes that say to rack or bottle your beer after a week, often these instructions bear little resemblance to reality.
Enjoy cracking your first beer, but don't freak if it's not what you expect yet.
Stouts and porters have taken me between 6 and 8 weeks to carb up..
I have a 1.090 Belgian strong that took three months to carb up.
And still needed a few months more to condition.
Temp and gravity are the two factors that contribute to the time it takes to carb beer. But if a beer's not ready yet, or seems low carbed, and you added the right amount of sugar to it, then it's not stalled,
it's just not time yet.

"patience."
