last time I made this style with a similar recipe I used 3 weeks in primary and bottled/kegged. Few weeks at room temp and a few weeks in the fridge and scored 47/50, still the highest I've ever gotten.
YMMV, but IMO this little beer is good quite at a young age, will improve over the first few months, and if handled well will last a surprisingly long period of time. Reminds me I need to make another.
good luck--
