Join me for My Chat with Dr Max Potterton from Boortmalt & Grace O'Reilly,  Waterford Whisky's Chief Agronomist. Max and Grace hosted me in Dalton's Grain Mill in Kilkenny, where Waterford Whisky's Mark Rainier stores his single farm origin barley in The Cathedral, the specially customised grain warehouse. Here, all the grains for Waterford's Single Malt are stored in separate bays, ready to be distilled.  Have a listen in on our chat, Sláinte.
