Independent bottlers take sourced casks of whisky, mature them, and then bottle them under their own brand names.

Justine Hazlehurst spent four years researching the Pattisons for her new book “Opening the Case: The Affairs of Pattisons’ Whisky,” and she joins us on this week’s WhiskyCast In-Depth.

Coopers have used everything from torches to infrared lamps to toast the inside of barrels.
