Master blender

A master blender is an individual who develops specific blended spirits using a combination of spirits with different characteristics. For example, in the Scotch whisky industry, master blenders choose which single malts and grain whiskies to combine to make particular brands of blended whisky.[1] A master blender is not the same thing as a master distiller, although one person may do both jobs at small craft distilleries. As the name suggests, the blender creates blends using spirits from different casks and is responsible for making sure the product remains consistent across different batches, while the distiller is either directly responsible for the mashing and distilling of spirits or simply holds the title as the administrative and marketing figurehead of the company.[2]

The term master blender is often associated with the whisky industry, but it is also used for professionals who blend other spirits, such as rum, cognac, brandy, and vodka.


In terms of whisky, the practice of blending distilled whiskies has likely existed in some form for centuries, but the craft of deliberately blending whiskies for flavour purposes began after Aeneas Coffey invented a new type of still to make grain whiskies in 1831.[3] William Sanderson and Andrew Usher are credited with making one of the first whisky blends in the 1860s.[3][4]

"The master blender role evolved in Scotland in the 19th century to manage the increasingly complex inventories held by Scotch whisky companies owning a number of distilleries and whisky brands."

— Rachel Barrie, Master Blender at BenRiach, GlenDronach, and Glenglassaugh Distilleries, The Whiskey Wash[5]


Being a master blender involves evaluating barreled spirits with different characteristics, such as age, storage conditions, and cask type, and then choosing the best combination of spirits to achieve a desired final product.[1] The master blender generally has two primary responsibilities:

  1. Make sure every batch produced under the same label tastes the same as previous batches[6]
  2. Create new appealing blends that deliberately differ from existing labels[6]

For some companies, the master blender also serves as the public figurehead for the company and may even have administrative and marketing duties outside of blending responsibilities.[6]

Blended whisky[edit]

Legal definitions for blended whiskies vary. In Scotland, blended whiskies may include grain whiskies and come from numerous distilleries with different malts. In the U.S., the standard is different, and blended whiskeys must contain at least 20 percent straight whiskey combined with neutral spirits or other whiskeys.[1]

A blend could be composed of as many as 20 or more different whiskies with different flavour profiles and ages, which makes maintaining product consistency over time a challenging accomplishment for a master blender. It is sometimes necessary to replace whiskies that go into a blend, and the master blender is responsible for accomplishing this feat without altering the characteristics of the final product.


Experience and a good "nose" are the two most important characteristics for a master blender, although some may also have a supporting academic background in chemistry, microbiology, or other related type of science.[2][6] Many blenders start as apprentices and work with blenders who have years of experience nosing spirits. It may take years of practice to develop the necessary skills, and the general consensus is that the title of master blender should be earned.[6][4][7]

Nosing spirits involves using the sense of smell to identify specific characteristics, such as different aromas and flavours, that work together to create the desired final product. After a particular blend is developed, then the master blender is responsible for ensuring all batches of that brand remain consistent in the future.[4]

In some cases, formal training outside of on-the-job training may be necessary. For example, according to Max Warner, Global Brand Ambassador for Chivas Regal:[8]

"You will need to have a qualification from the Institute of Brewing and Distilling to be considered for a position within the Blending Team. There are tests carried out on blenders' olfactory senses (the nose), as this is the most important ‘device’ for appraising and assessing Whisky."
