Mac-Talla Strata 15 Year OldMac Talla Strata is a new secret Islay single malt scotch whisky with a rocky title, from an unnamed distillery. It is made by the Morrison family, one of Scotland's oldest whisky families with generations of knowledge in the industry. Mac Talla means 'echo' in Scottish Gaelic and reflects the tastes of Islay. 'Strata' as the plural of 'stratum', refers to the many igneous rock formations that are visible along Islays rugged but breath taking shores.
