The Celt IV follows on from our previous and very popular Celt III and is also a highly peated single malt. Again, it was initially matured in ex-Bourbon casks before a final finishing period in high quality Marsala wine casks from the Martinez winery in Sicily. It is bottled without chill filtration and at a generous 46% strength without any colouring. Each Celt release is designed to be opened and enjoyed by our customers with friends, family and other loved ones. We hope you enjoy it!
