Thomas succeeds Helen Mulholland who began her long career at The Old Bushmills Distillery almost 30 years ago.
Born in Ballymoney, just 15 minutes from The Old Bushmills Distillery, Thomas joined the Bushmills team in 2004 and in 2017 developed The Sexton Single Malt.
“It is a privilege to be appointed as master blender for Bushmills Irish Whiskey,” said Thomas. “The Old Bushmills Distillery is a very special place and I’m excited to explore my passion for developing new whiskeys and experimenting with different casks and flavours, while still maintaining the iconic Bushmills taste and quality.
“The craftmanship and passion that goes into Bushmills is something that has truly captured my imagination. Whiskey fans know Bushmills Irish Whiskey for the brand’s 400 years of quality and taste, so part of my job will be ensuring that we continue to meet that high standard."
Colum Egan, Bushmills master distiller, added: “Over the years Alex has demonstrated exceptional skills in the art of blending and her passion and pursuit of excellence has truly made her one of the rising stars in Irish whiskey.”
