Old Grand Dad was Bukowskis favourite drink, so it's hard not to love it! In Germany still single malt rules, but the bourbon community is rising, slowly, but rising. Five years ago the only bourbon you could buy was JB, then they had JD, which is known as "bourbon" here in "Deutscheländ", now they have Maker's Mark, Four Roses, OGD sometimes. I mostly buy in online-shops. Old Grand Dad is great, best value I think. I never had the OGD BiB, because especially this one is hard to get.
