Certain beers like Russian Imperial Stouts, Imperial IPA's, Specialty Beers, Old Ales, etc...seem to deserve they be individually bottled.
I keg 98% of my beer. I also bottle a 12 pack or more from each keg to preserve for later on down the road.
There's nothing like drawing a pint of an easy drinking ale. The taste is fantastic.
These "special" beers though??? They seem to taste better with the ritual of picking out the bottle, grabbing the openner, popping that cap and pouring a nice glass.
I have seven taps flowing and still love to open a bottle of my "reserve" every now and again.
