For those following the saga, I finally got to taste the bourbon barrel aged coffee this morning. It definitely tastes bourbon-y. I guess you could describe it as tasting like bourbon coffee. It was pretty nice to sip on but I think it's something to try for it's uniqueness, not really an every day blend.
It took this long because I ordered it, then I had to chase it up because it hadn't arrived, then it arrived about an hour before I headed to the airport to visit my parents for a week and they don't have equipment to deal with beans and I was only taking carry on... I'm home now and finally got to taste it.
