Harviestoun Ola Dubh 12year Cask pours black with a modest spattered head that reduces slowly, leaving behind textbook lacing. The aroma is delicious; smoky Worcestershire sauce, leather, iodine and grilled steak. Flavors of smoky-sweet malts, roasted peat, coffee beans and a well-bittered finish. Overall this is a rather exotic brew with a defined barrel influence. It’s refined rather than over the top and very delicious indeed.
