FAQ: Whisky Terminology

Compiled from 100 professional whisky terms, this FAQ covers common questions about categories, regions, production, cask maturation, tasting, bottling, and more. It is suitable for beginners, reference, and whisky conversations.

1. Basic Categories and Naming

Q1: Is there a difference between “Whisky” and “Whiskey”? What do they represent?

A: Yes. The spelling is mainly used to distinguish regions of origin. Whisky without an “e” is commonly used for Scotch, Japanese, Canadian, and Indian whisky. Whiskey with an “e” is commonly used for Irish and American whiskey. This spelling distinction was originally adopted by Irish distilleries to differentiate their products from Scotch whisky.

Q2: What are the legal requirements for Scotch Whisky?

A: Scotch whisky must be mashed, fermented, distilled, and matured entirely in Scotland. It must be aged for at least 3 years, bottled at no less than 40% ABV, and artificial flavoring is prohibited.

Q3: What is the difference between Single Malt, Blended Whisky, and Blended Malt?

A:

  1. Single Malt: Produced by one single distillery, made from 100% malted barley, and distilled in pot stills.
  2. Blended Whisky: A blend of malt whisky and grain whisky.
  3. Blended Malt: A blend of malt whiskies from multiple distilleries, containing no grain whisky.

Q4: What are Grain Whisky and Single Grain Whisky?

A: Grain whisky is made from grains such as corn or wheat and is usually distilled continuously in column stills. It has a lighter flavor profile and is mostly used for blending. Single Grain refers to grain whisky produced by a single distillery.

Q5: What is Single Pot Still Whiskey?

A: Single Pot Still is a distinctive Irish whiskey style made from both malted and unmalted barley. It often has a unique spicy character.

2. Whisky by Country and Region

Q6: How are Bourbon, Tennessee Whiskey, and Rye Whiskey defined?

A:

  1. Bourbon: Must contain at least 51% corn in the mash bill and must be aged in new charred oak barrels. Its flavors are typically vanilla, caramel, and toasted oak.
  2. Tennessee Whiskey: A branch of bourbon-style whiskey that includes an additional maple charcoal filtration process, making it smoother. Jack Daniel’s is the best-known example.
  3. Rye Whiskey: Must contain at least 51% rye in the mash bill. It is usually drier, spicier, and more aromatic.

Q7: What are the characteristics of Canadian Whisky?

A: Different grains are usually distilled and matured separately, then blended together before bottling. Crown Royal is a representative Canadian whisky brand.

Q8: What makes Japanese Whisky distinctive?

A: Japanese whisky follows many Scotch whisky production traditions. Mizunara oak casks are a signature feature, giving the whisky distinctive sandalwood-like aromas. Well-known brands include Yamazaki, Hakushu, and Hibiki. Some non-authentic “pseudo-Japanese whisky” products exist on the market, so buyers should be cautious.

Q9: What is the typical style of Irish Whiskey?

A: Irish whiskey is commonly triple-distilled and often made with unmalted barley. It tends to be smooth, light, and approachable. Jameson is a recommended entry-level choice.

Q10: What are Indian Whisky and World Whisky?

A: India is the world’s largest whisky consumption market, and Amrut is one of its well-known brands. World Whisky generally refers to whisky produced outside the five major regions: Scotland, the United States, Ireland, Canada, and Japan. Kavalan from Taiwan is a notable example.

Q11: What are the styles of the six major Scotch whisky regions?

A:

  1. Speyside: The most densely populated whisky region in Scotland, known for sweet fruity aromas and a beginner-friendly style.
  2. Highlands: The largest whisky region in Scotland, with diverse styles and no single unified flavor profile.
  3. Lowlands: Soft, light, and often grassy in character. Auchentoshan is a representative distillery.
  4. Islay: Famous for strong peat flavors, often showing iodine and seaweed notes. The style is bold and intense.
  5. Campbeltown: A small region with very few remaining distilleries. Springbank is its benchmark producer.
  6. Islands: Often shows coastal salinity and sea breeze notes, though most bottlings are not heavily peated.

3. Ingredients and Production Process

Q12: What role does Malted Barley play in whisky?

A: When barley germinates, its starches are converted into fermentable sugars. Malted barley is the core ingredient of single malt whisky.

Q13: What are Peat and PPM?

A: Peat is an organic soil layer formed from decomposed plant matter. When burned, its smoke is used to dry malted barley, giving whisky flavors such as peat smoke, bonfire, iodine, and medicinal notes. PPM, or phenol parts per million, measures peat concentration. Regular whiskies are often below 5 PPM, Islay whiskies are commonly around 20–50 PPM, and heavily peated expressions can exceed 300 PPM. However, a higher PPM does not always mean the whisky will taste harsher or more pungent.

Q14: What are the key steps in whisky production?

A: Malting → drying/kilning, where peat smoke may be applied → mashing, producing wort → fermentation, producing wash at around 6%–8% ABV → distillation → cask maturation.

Q15: What is the difference between Pot Stills and Column Stills?

A: Pot Stills are copper stills used mainly for single malt whisky. They produce rich and complex flavors. Column Stills are used for continuous distillation, offering high efficiency and cleaner spirit, and are commonly used for grain whisky.

Q16: What are Heads, Heart, and Tails in distillation?

A: These are different fractions collected during distillation:

  1. Heads: Contain unwanted compounds and harsh aromas. They are discarded or recycled.
  2. Heart: The best-quality portion and the only part used for maturation. It defines the core style of the whisky.
  3. Tails: Contain heavier compounds with unpleasant flavors and are also discarded or redistilled.

Q17: What is New Make Spirit?

A: New Make Spirit is the freshly distilled spirit before cask maturation. It is usually around 68%–72% ABV and tastes very different from finished whisky.

4. Oak Casks and Maturation

Q18: Why are oak casks called the “second soul” of whisky?

A: More than 70% of whisky’s flavor comes from the oak cask. The wood type, previous contents, and number of times the cask has been used can greatly affect the whisky’s flavor, color, and mouthfeel.

Q19: What are common cask sizes and their characteristics?

A:

  1. Hogshead: Around 250 liters. Widely used in Scotland and often rebuilt from used bourbon barrels.
  2. Sherry Butt: Around 500 liters. Adds dried fruit and chocolate flavors and is a classic cask type associated with Macallan.
  3. Barrique: Around 225 liters, originally used for wine.
  4. Quarter Cask: Around 125–130 liters. Smaller cask size allows faster maturation.
  5. Mizunara Cask: A Japanese oak cask known for sandalwood-like aromas and high cost.

Q20: How do Bourbon Casks and Sherry Casks differ in flavor?

A: Bourbon Casks are used for more than 90% of Scotch whisky maturation and bring vanilla, coconut, and honey notes. Sherry Casks are much more expensive and give the whisky a deeper color, dried fruit notes, and dark chocolate flavors.

Q21: What is the difference between First Fill, Refill, and Virgin Oak?

A:

  1. First Fill: A cask used to mature whisky for the first time, giving stronger cask influence.
  2. Refill: A cask used for the second or third time, offering a gentler oak influence.
  3. Virgin Oak: A brand-new oak cask that has never held any liquid before, usually giving strong tannins and woody flavors.

Q22: What are Cask Finish, Double Matured, and Triple Matured?

A:

  1. Cask Finish: After the main maturation, the whisky is transferred to another type of cask for a shorter finishing period.
  2. Double Matured: The whisky is matured in two different types of casks and then combined for bottling.
  3. Triple Matured: The whisky is matured successively in three different types of casks, making the process more complex.

Q23: What is the Angel’s Share?

A: During cask maturation, around 2% of the whisky evaporates naturally each year. This lost portion is known as the “Angel’s Share.” The longer the maturation period, the greater the loss.

5. Age, Alcohol Strength, and Tasting

Q24: What do Age Statement and NAS mean?

A: Age Statement refers to the age shown on the bottle, indicating that the youngest whisky inside has been matured for at least that many years. NAS, or No Age Statement, means the bottle does not state the maturation age and has become increasingly common in recent years.

Q25: What do ABV and Cask Strength mean?

A: ABV stands for Alcohol by Volume. Scotch whisky must be bottled at a minimum of 40% ABV. Cask Strength means the whisky is bottled directly from the cask without dilution, usually at 50%–65% ABV, resulting in a more intense flavor profile.

Q26: What are the advantages of Non-Chill Filtered and Natural Colour whisky?

A: Non-chill filtration retains more natural compounds in the whisky, giving it a richer and oilier mouthfeel. The whisky may become cloudy at low temperatures, which is normal. Natural colour means the whisky’s color comes entirely from the oak cask, with no added caramel coloring, also known as E150a. It is often seen as a sign of quality.

Q27: What are the three core aspects of whisky tasting?

A:

  1. Nose: The first step in tasting. Much of whisky’s flavor is perceived through smell.
  2. Palate: The taste, texture, and development after the whisky enters the mouth.
  3. Finish / Aftertaste: The aromas and flavors remaining after swallowing. The length of the finish is an important quality indicator.

Q28: How do you judge whisky Body?

A: Body refers to the “weight” or texture of the whisky in the mouth. It is usually described as light, medium, or full-bodied.

6. Bottling, Products, and Industry Terms

Q29: What is the difference between OB and IB?

A: OB, or Official Bottling, refers to whisky bottled and released by the distillery itself. It usually forms the core product range of a brand. IB, or Independent Bottling, refers to whisky casks purchased by third-party bottlers, who then bottle and sell the whisky under their own labels.

Q30: What do Single Cask and Small Batch mean?

A: Single Cask means all the whisky in the bottle comes from one single cask, making the release limited in quantity. Small Batch usually refers to whisky made by blending liquid from 2 to 12 casks, distinguishing it from large-scale industrial blending.

Q31: What do Core Range, Limited Edition, and Miniature mean?

A: Core Range refers to a distillery’s regular, stable product lineup and is usually the best way to understand the brand’s style. Limited Edition refers to special releases with limited production, though limited quantity does not necessarily mean better quality. Miniature refers to small bottles, usually 30–50 ml, suitable for tasting or collecting.

Q32: What is the Solera System?

A: The Solera System is a layered maturation and blending method. New whisky is added to upper-level casks, while whisky for bottling is drawn from the lowest level. Glenfiddich’s Solera series is a representative example.

Q33: What are some common and interesting whisky industry terms?

A:

  1. Uisge Beatha: Scottish Gaelic for “water of life,” the origin of the word “whisky.”
  2. Dram: A Scottish term meaning a small pour of whisky.
  3. Sláinte: A Scottish Gaelic toast meaning “cheers.”
  4. Glencairn Glass: A standard whisky tasting glass designed to concentrate aromas and suit tasting occasions.
  5. SWA: The Scotch Whisky Association, responsible for protecting Scotch whisky regulations and reputation.
