Oooh. I'm sorry to say I haven't had the opportunity to try that 21yo Balvenie Portwood yet Gordie, but Mike(FCTush) once brought some of the 14yo Balvenie Carribean Cask to the SWTF for us to try, and that turned out to be delicioUs!
Yep! Just like a good Single Malt Scotch, you might call me "an acquired taste" TOO.(among the many OTHER things you may care to call me, of course)
