WSET Spirits Level 2 & 3 Study Notes: Key Facts & Exam Tips
When I studied for my WSET Spirits exams, I filled notebooks with the small facts that examiners love and textbooks scatter. This is that notebook, cleaned up and organised: the key points for Level 2 and Level 3, category by category. Bookmark it, revise from it, and good luck with your exam.
1) General Spirit Production & Techniques
Filtration: some producers use activated charcoal filtration to polish or remove colour.
Flavouring methods:
Maceration (soaking) gives a tincture; redistilling the flavoured spirit gives a distillate.
Three redistillation approaches: (1) short maceration then distillation; (2) botanicals held in the vapour path in botanical baskets for a lighter style; (3) vacuum distillation at low temperature, which protects delicate aromas like cucumber but needs expensive equipment.
Cold compounding: simply blending flavourings into a base spirit, no distillation involved.
2) Whisky & Whiskey
Raw materials and mashing
Starch is a chain of glucose. Barley is malted; other grains are cooked, then mixed with malted barley so its enzymes can work.
Mashing: crushed malt meets hot water, starch unrolls, enzymes convert it to glucose, and the sweet liquid wort is born.
Scotch rule: added (bought-in) enzymes are not permitted; the malt must do the work.
Oak and maturation
New oak gives more colour and flavour than reused oak. Oak's signature: vanilla, coconut, sweet spice.
Detail worth remembering: casks stored at the top of warehouses (warmer) tend to take on more colour and flavour.
USA
Bourbon: at least 51% corn; distilled to a maximum of 80% ABV; no sugar or caramel permitted (strictest for Straight Bourbon). Rye in the mash adds spice and rye-bread notes; wheat adds soft, doughy notes. Fermentation can create banana and citrus aromas.
Tennessee whiskey: filtered through maple wood charcoal before aging (the Lincoln County Process).
Rye whiskey: at least 51% rye; spicy, lemon zest, rye bread.
Bottled in Bond: one distillery, one season, at least 4 years in wood, and only water may be added. The rule applies to other American spirits too, not just whiskey.
America recognises more than 36 legal whiskey categories in total. Exam tip: know the big four above.
Canada
Grains are often fermented and distilled separately, then blended: typically high-strength, low-intensity corn whisky plus low-strength, high-intensity rye.
Aged in wooden barrels; oak is customary but not legally required.
The famous rule: up to 9.09% of the blend may be other aged spirits or fortified wine (minimum 2 years old).
Sour mash: returning some stillage to the next fermentation.
Scale example from my notes: the Hiram Walker distillery can process around 180,000 litres a day, with 19 grain stills, and a typical angels' share of about 3%.
Scotland
Caramel colouring (E150a) is allowed; sugar is not.
Tall stills create more reflux in the swan neck, giving a lighter spirit; short stills pass heavier vapours through, giving bolder aromas. (The full story, with distillery examples: How Whisky Is Made, Part 2 and Worm Tubs vs Shell & Tube.)
Ireland
Unmalted barley in the mash gives the nutty, oily character of the single pot still tradition.
Japan
Japanese distilleries traditionally do not trade spirit with each other, so each produces a wide range of styles in-house. Yamazaki, Japan's first whisky distillery, was founded in 1923 (the full story: Japanese Whisky: The Taketsuru Story). Pop culture footnote: the Hibiki 17 scene in Lost in Translation marked an early moment in Japanese whisky's global rise.
3) Rum
Materials and fermentation
Made from sugarcane juice, syrup, or molasses, never neutral grain spirit.
Molasses gives caramel and brown sugar aromas; blackstrap molasses is common in the Caribbean. Molasses and syrup are diluted with water before fermentation.
Jamaica: high-ester, intensely fruity rums, often fermented with ambient (wild) yeast.
Distillation, marks, and aging
Light marks: distilled to around 90% ABV, usually in columns. Heavy marks: usually pot still, lower strength, more character.
Both types can mature in oak; reused barrels are the norm. Aging in Europe is called continental aging; the tropics age spirit much faster.
Rums are frequently blended across marks, distilleries, and even countries.
Common practices
Short aging followed by charcoal filtration to remove colour (this is how "white" rum can be aged rum).
Caramel colouring is widely used.
Sweetening before bottling is permitted in some traditions, including Jamaica.
The white / gold / dark categories describe colour, not quality or age.
Regions and styles (exam favourites)
Martinique (Rhum Agricole): cane juice, column distilled, grassy and herbaceous. Rhum blanc: colourless, rested in inert vessels, dry. Rhum vieux: minimum 3 years, always cane juice.
Cachaça (Brazil): cane juice, mostly unaged, vegetal and fruity, relatively low strength, may be slightly sweetened; aged versions often use local hardwoods, not oak.
Cuba & Puerto Rico: molasses, column stills to high strength, must be oak-aged, dry and light-to-medium with toffee notes; colour often removed by filtration.
Jamaica: pronounced, complex, oily, high-ester; pot and column blends; overproof at 57.15% ABV (100 old British proof). Labeling nuance: "Jamaican Rum" must be aged and bottled in Jamaica; "Rum from Jamaica" may be sweetened and bottled elsewhere.
Barbados: rum's birthplace; pot + column blends, molasses, dry and rich.
Guyana: one active distillery preserving the historic stills of closed rum houses, including wooden stills; known for single-mark bottlings.
Spiced rums: oak-aged base plus macerated natural flavours; caramel and sugar optional.

4) Agave Spirits (Tequila & Mezcal)
The plant
Agave lives roughly 15-20 years and stores its carbohydrates as fructans, at their peak just before flowering.
Herbaceous agave aromas: bell pepper, vegetal notes, olive, black pepper.
Cooking, extraction, fermentation
Heat converts fructans into fermentable sugars and develops the cooked-agave flavours in the piña.
Cooking: brick ovens with steam (traditional) or autoclaves, stainless pressure vessels (modern). The diffuserextracts sugars without real cooking; producers chasing maximum agave character avoid it.
Formulation is the preparation of the sweet liquid for fermentation. Mezcal often ferments with agave fibres included and ambient yeast.
Distillation and aging
Often distilled below 60% ABV to keep complexity. Rested in inert vessels or briefly in oak, depending on style.
Tequila
Non-agave sugars may be added, but at least 51% of sugars must come from agave ("mixto" is the informal name for this; it is not an official label term; the words to look for on quality bottles are 100% agave).
Five permitted states; Jalisco is the heart. Highlands tequilas are fruitier than valley tequilas.
Aging terms: Blanco/Plata: no minimum. Reposado: 2 months. Añejo: 1 year. Extra Añejo: 3 years.
Gold tequila: the caramel colouring known as abocante is allowed only in tequila, adding a textural smoothness.
Mezcal
Nine permitted states; Oaxaca is the most important. Made from any agave species; Espadín is the most common.
Piñas are commonly pit-roasted, giving the signature earthy smoke. Usually unaged, rested in inert vessels.
Tahona stone milling is traditional.
The three legal categories, strictest last: Mezcal (any cooking, column stills allowed), Artesanal (pit or brick-oven roast, hand or tahona milling, direct-fired copper or clay pot stills), Ancestral (pit roast, hand or tahona, direct-fired clay stills only).
Aging terms: blanco (unaged), reposado (2 months), añejo (1 year).
(The story version: All Tequila Is Mezcal, But Not All Mezcal Is Tequila.)
5) Fruit Spirits & Brandies
Pathways
Most common: ferment the fruit, then distil. Where juice yield is low (some berries), maceration + redistillation is used instead; the same technique makes high-quality flavoured vodkas. Pot and column stills both appear.
Any grapes can be used; white grapes are more common than black. Most grape and apple spirits are matured.
Cognac
Grapes: predominantly Ugni Blanc (high acid, low aroma, which concentrates beautifully on distillation).
Double pot distillation in copper, often direct-fired, traditionally with worm-tub condensers.
Minimum 2 years maturation, typically starting in new oak then moving to older barrels. Very old cognacs are moved to glass demijohns to stop aging.
Caramel and slight sweetening are common, giving an off-dry finish.
Armagnac
Grapes: Ugni Blanc, Baco Blanc (prune notes), Folle Blanche (floral).
Distilled in short column stills to lower strength, keeping more character. Vintage-dated bottlings are common.
Blanche Armagnac: rested 3 months in stainless steel. Key regions: Bas-Armagnac and Ténarèze.
Calvados
Normandy; mostly apples, matured in large old oak, with a distinct cider-apple aroma. Pot and column stills both used.
Grappa
Italy; distilled from pomace (the skins and seeds left from winemaking). Many styles unaged; aromatic Moscato is a favourite; some rest a year or more in inert vessels.
Pisco
Peru and Chile; highly aromatic grapes, pot distilled. Peruvian pisco must be unaged; Chilean may see brief wood. Colourless, pure, intensely fruity and floral.
6) Gin, Vodka, Absinthe, Bitters, Liqueurs
Gin
Core botanicals: juniper, coriander seed, citrus peel, angelica root, orris root.
EU: the base must be neutral spirit; USA: any distilled base is allowed.
Vapour infusion: botanicals suspended in the vapour path (the Carterhead approach; Bombay Sapphire is the famous example). Vacuum distillation captures heat-sensitive botanicals.
Gin distilleries usually do not recycle heads and tails.
Styles: juniper-forward vs contemporary. Old Tom: the sweetened style. Oak-aged gins take on a pale lemon colour.
(Deeper: Gin Styles Explained and Juniper: The Berry That Isn't a Berry.)
Flavoured vodka
Traditional: maceration with honey, fruits, herbs (bison grass is the classic). Modern: everything from vanilla to chili.
Absinthe vs Pastis
Absinthe: must contain wormwood, bottled strong, traditionally diluted with water at serving, not sweetened.
Pastis: sweetened, and must use liquorice. That pairing (wormwood vs liquorice, dry vs sweet) is a classic exam question.
Bitter spirits (amaro) and cocktail bitters
Bitterness is extracted by maceration; typical botanicals: quinine, gentian, bitter orange, artichoke.
Bitterness is a taste, perceived on the palate, not an aroma. Served as aperitif or digestif. Cocktail bitters are the concentrated, high-strength cousins.
Liqueurs
Sweetened, flavoured spirits. Most use neutral bases, but note the exceptions examiners love: Grand Marnier(Cognac base) and Drambuie (Scotch base). Cream liqueurs are among the only truly opaque drinks in the bar.
7) Aromatised & Fortified Wines
Vermouth: aromatised wine that must be flavoured with wormwood; most vermouths are also sweetened. Insider fact: red vermouth is usually white wine plus caramel colour, not red wine.
Quinquina (France) and Chinato (Italy): flavoured with quinine. Americano: wormwood and gentian.
Mistelle: spirit added to grape juice before fermentation, keeping the natural sugar.
Fortification range: roughly 14.5-22% ABV.
Port: grape spirit is added during fermentation, stopping the yeast and keeping sweetness. Serve port, and sweet wines generally, chilled.
In cocktails, aromatised wines contribute sweetness, bitterness, and acidity.
8) Cocktails
Short drinks
Few ingredients; balance comes from dilution while shaking or stirring.
Spirit-forward classics: Old Fashioned, Sazerac, Manhattan, Martini, Negroni.
Short sours: Pisco Sour, Whiskey Sour, Daiquiri, Sidecar, Margarita, Clover Club. Texture trick: egg white or aquafaba (chickpea water).
Long drinks
Lengthened with soda, tonic, or other mixers.
Highball family: Cuba Libre, Gin & Tonic, Vodka Tonic, Greyhound (vodka + grapefruit), Horse's Neck (cognac + ginger ale + bitters), Americano (Campari + sweet vermouth + soda).
Long sours: Tom Collins, Paloma, French 75, Mojito, Singapore Sling.
