Hacker-Pschorr Weisse Dark

I picked this bottle up for a very reasonable price, somewhere around $1.75.  From looking at the bottom of the bottle (after the pour), the brew appears to have been bottle conditioned.  The brew shines a cloudy amber-brown.  A pretty white head slims down to a silky rim environment.  It smells of yeast, wheat bread, and banana, but the aromas are toasted to a pleasant degree.

A lot of acidity comes out first with the initial sip.  Muted fruit, and a buttery finish.  Yeasty on the tongue.  Thin in the flavor category.  Noticeable attenuation.  Medium-bodied.  Somewhat bland & a little disappointing.  I've also discovered a "Produced On" indicator on the bottom-right corner of the label: 10/08.  Tell me that's a mistake...
