Beer, from scratch

What beer actually is

Definition. Four ingredients, one process, endless variation. India has a legal definition, which is a useful place for a beginner to start because it is precise.

Unpack that and you get the whole craft. Malted grain supplies sugar and colour. Water is the medium and, less obviously, a flavour ingredient. Hops supply bitterness, aroma and preservation. Yeast eats the sugar, makes alcohol and CO₂, and, the part beginners always miss, creates a large share of the flavour itself.

Ale versus lager

The one split that organises everything. Almost every beer in the world falls on one side of this line. It is a difference of yeast species and temperature, and everything else follows from it.

The instructive exceptions

Kölsch

Fermented warm with ale yeast, then cold-conditioned like a lager. Result: a pale, delicate beer that drinks like a lager but carries a faint ale fruitiness. Cologne, Germany.

Baltic Porter

Called a porter, historically an ale style, but fermented cold with lager yeast. 6.5–9.5% ABV, dark, smooth, dried-fruit rich. The name tells you nothing about the yeast.

Lambic & Gueuze

Neither. Spontaneously fermented by wild yeast and bacteria from the open air of Brussels' Senne Valley. Sour, funky, and at 0–10 IBU essentially unbittered.

Takeaway: style names are historical accidents, not a taxonomy. The yeast is the real fact.

The four ingredients, and what each does to the glass

Composition. Read this as a drinker: the question is never "how is it made", it is "why does it taste like that".

Reading the numbers on a tap list

Units. Four abbreviations do almost all the work. The ranges quoted here are derived from the 66-style dataset below, so they describe the real span of beer rather than a textbook ideal.

ABV Alcohol by volume

What share of the liquid is pure alcohol. A 5% beer is 5% ethanol by volume. Across the styles below it runs from 2.8% (American Light Lager, Berliner Weisse) to 14% (Eisbock). In India, beer is legally capped at 8.0%.

IBU International Bitterness Units

A laboratory measure of bitter compounds. Across these styles it runs from 0 (Lambic, Gueuze) to 100 (Double IPA, American Barleywine). Critically, IBU is not perceived bitterness, because sweetness masks it. An Imperial Stout at 50–90 IBU tastes far less bitter than an American Pale Ale at 30–50, because the stout has enormous residual malt sweetness to balance against.

SRM Standard Reference Method

Colour, as a number. Low is pale, high is dark. In this dataset 2 is palest straw (American Light Lager, Berliner Weisse), 10–17 is amber to copper, and 40 is effectively black (Irish Stout, Imperial Stout). Europe uses EBC instead, which is roughly double the SRM figure.

OG / FG Original & final gravity

Sugar density before and after fermentation, written as 1.048, 1.012 and so on. The gap between them is what the yeast ate, so it predicts alcohol; how high the FG lands predicts body and sweetness. Czech Premium Pale Lager runs OG 1.044–1.060 down to FG 1.013–1.017.

°P Degrees Plato

The same sugar measurement on a different scale, standard in continental Europe. This is the most common beginner trap. A Czech beer labelled "12°" is 12 degrees Plato, a measure of sugar density, not strength. That beer is around 5% ABV, not 12%. Czech pubs label beers 10°, 11°, 12° routinely.

66 styles, with real specifications

The map. Every figure here comes directly from the BJCP 2021 Style Guidelines, the reference beer judges are examined against. Filter, search and sort to find your way around.

Where to start, in eight rungs

The route in. Every rung introduces exactly one new idea, and each is chosen so its numbers make the lesson obvious. Climb in order and you will understand beer by tasting rather than by reading.

0

Where you already are: International Pale Lager

4.5–6.0% ABV · 18–25 IBU · SRM 2–6

Kingfisher, Budweiser, Heineken, Corona, Tuborg. This is the baseline, not an insult. Know its numbers so every later rung has something to measure against: mild bitterness, pale colour, minimal yeast character.

1

The same thing, done properly: Munich Helles or German Pils

Helles 4.7–5.4% · 16–22 IBU  |  Pils 4.4–5.2% · 22–40 IBU

Identical family, identical strength, far more flavour. Helles shows you what malt tastes like when nothing is hiding it. German Pils, at up to 40 IBU, shows you what hop bitterness feels like in a beer you already understand. Lesson: flavour is not a function of strength.

2

Meet yeast: Weissbier or Witbier

Weissbier 4.3–5.6% · 8–15 IBU  |  Witbier 4.5–5.5% · 8–20 IBU

Among the least bitter beers in the entire guide, yet enormously flavourful: banana and clove in the German, coriander and orange peel in the Belgian. This is the rung for anyone who thinks they dislike beer. If the problem was bitterness, these solve it at a stroke.

3

Meet malt and break the colour myth: Munich Dunkel or Vienna Lager

Dunkel 4.5–5.6% · 18–28 IBU · SRM 17–28  |  Vienna 4.7–5.5% · 18–30 IBU · SRM 9–15

Visibly dark, no stronger than a Kingfisher, and no more bitter. Toasted bread crust, nuts, light chocolate. Lesson: dark does not mean strong, heavy or bitter. That single correction unlocks half the beer world.

4

Meet roast: Irish Stout

3.8–5.0% ABV · 25–45 IBU · SRM 25–40

Black as it gets, and weaker than most Indian lagers. Coffee and dark chocolate come from roasted grain, not from hops or alcohol. On a nitro pour it is also your introduction to how gas changes texture. Lesson: roast is a fourth flavour axis, separate from malt sweetness, hops and yeast.

5

Meet hops properly: American Pale Ale, then American IPA

APA 4.5–6.2% · 30–50 IBU  |  IPA 5.5–7.5% · 40–70 IBU

Do these in this order, and only now. Citrus, pine and resin are hop flavours, distinct from hop bitterness. If the IPA is too much, try a Hazy IPA (6–9%, 25–60 IBU): same aroma intensity, markedly less bite, because the hops went in late rather than early.

6

Meet Belgian yeast: Dubbel, then Tripel

Dubbel 6.0–7.6% · 15–25 IBU  |  Tripel 7.5–9.5% · 20–40 IBU

Now the alcohol climbs, and the point is how well it hides. A Tripel at 9.5% with only 20–40 IBU tastes of spice and citrus rather than heat. Lesson: strength is something a brewer can conceal, which is precisely why it is worth counting your standard drinks.

7

The frontier: Gose, then Imperial Stout or Barleywine

Gose 4.2–4.8% · 5–12 IBU  |  Imperial Stout 8–12% · 50–90 IBU

Gose is the gentlest possible door into sour beer: low alcohol, nearly no bitterness, tart and faintly salty. At the other extreme, Imperial Stout and Barleywine are sipping beers where every axis is turned up at once. If these still read as "beer", you have arrived.

Temperature, glass, pour and food

Handling. Most bad beer is mishandled rather than badly brewed. Four variables account for nearly all of it, and one of them matters enormously if you eat Indian food.

Temperature

The Certified Cicerone syllabus states the band plainly: beer "should be served between 38 and 55 °F (3–13 °C) depending upon its style", and "reveals more flavor as its temperature increases".

There is no style-by-style temperature table in any authoritative source retrieved for this guide, so none is invented here. What exists is the governing rule, from the Brewers Association: "Assume that the higher the ABV, the warmer the serving temperature." Around 45–50 °F (7–10 °C) is described as common for many styles.

Glassware

The Brewers Association publishes a five-shape chart with explicit style mappings and stated functions. Those five are below. Cicerone adds two selection rules: higher-alcohol beers go in smaller glasses, and the glass must leave room for an appropriately sized head.

The mechanisms, in the chart's own terms: a stem or handle keeps body heat away from the beer; an outward-curved upper shape traps and concentrates aroma; an inward-curving shape concentrates foam; a large bowl invites you to cup and deliberately warm a strong beer.

The pour

Beer and Indian food

The standard framework has three principles: complement (shared flavours resonate), contrast (an opposing flavour highlights the dish), and cut (carbonation, sourness and bitterness lift rich or fatty flavours off the palate). Before any of those, match intensities so neither side overwhelms the other.

Then there is chilli, and here the Cicerone syllabus is unusually specific. It lists which beer traits act on capsaicin heat, and the answer is counterintuitive:

Foam, lacing and freshness

Reading an Indian beer label

India, the law. India regulates beer labels in unusual detail, and several of those rules explain things you have probably noticed without understanding, including why the ABV is so often a band rather than a number.

Mild versus strong: two different rulebooks

This is a genuine trap. Food law and excise law draw the line in different places, and excise law is set state by state. Both are real, and they do not agree.

FSSAI also sets hard limits for beer sold in India: pH 3.3–4.8, CO₂ 1.8–3.6 volumes, methanol max 50 mg/l, lead max 0.2 mg/l. Beer must be clear, wheat beer excepted, and bottled or canned beer must be pasteurised or filter-sterilised. Draught beer is exempt from that last rule, which is precisely why draught at a microbrewery can taste fresher and fuller than the same beer from a bottle.

How much are you actually drinking?

India has an official standard drink, defined in the beer regulation itself: one standard drink contains 12.7 ml of alcohol by volume at 20 °C (reg. 5.2). Printing the count on the label is voluntary, so you will rarely see it, which makes it worth computing yourself.

What is actually in the fridge

India, the market. Four companies account for most of what you can buy in India. Here is who owns what, and one finding that matters more than the roster itself.

Who owns what

Styles below are only as the company itself describes them. Blank means the company does not state it.

Heineken N.V. holds 61.5% of United Breweries Limited. Note that Simba's four-way split (Wit, Stout, Lager, Strong) is unusually informative for an Indian brand: most competitors name a beer without ever naming its style.

Market structure

Microbreweries, as a state actually regulates them

Haryana's Excise Policy 2025-27 is a concrete example of the licensing regime behind every brewpub you drink at. A microbrewery licence is form L-10C, and it is restrictive:

• Granted only to existing hotel or restaurant licence holders (L-4 / L-5)
• Beer produced must not exceed 8% v/v
• On-site consumption only. The licensee may not sell it for off-premises drinking, which is why you cannot buy a growler to take home
• Licence fee ₹30 lakh in Gurugram, ₹20 lakh in Faridabad, Panchkula and Sonepat, ₹10 lakh elsewhere, plus ₹2 lakh security
• Excise duty ₹40 per bulk litre on installed fermenting-tank capacity
• Every batch certified fit by a qualified chemist; monthly government lab sampling

The policy's stated rationale is "to promote healthy drinking habit of liquor with low alcoholic content". United Breweries describes craft and microbrewery segments as "relatively small" but "influencing consumer preferences around taste, freshness, and experience".

Tasting, and what "off" tastes like

Sensory. Professional judging follows a fixed order. Learning it gives you language for things you already perceive but cannot name.

1

Appearance

Colour, clarity, head size, head retention, lacing down the glass. Use a consistent background.

2

Aroma

Swirl and sniff. Most of what you call "taste" is smell. Malt, hop and yeast character separate out here first.

3

Flavour

Let it reach the whole mouth. Identify malt, hop, yeast, and the balance between sweetness and bitterness.

4

Mouthfeel

Body, carbonation, warmth, creaminess, and astringency, which is a mouthfeel rather than a flavour.

5

Finish

What happens after you swallow. Dry or sweet, short or lingering. Perception continues past the swallow.

Building vocabulary, one rung at a time

The BJCP grades judges on descriptive precision, and its own escalation example is the clearest guide to getting better. The same beer, described at five levels of skill:

Beginner

"hoppy aroma"

Recognised

"American hop aroma"

Certified

"moderate American hop aroma"

National

"moderate citrusy American hop aroma"

Master

"moderate citrusy American hop aroma, with notes of tangerine and grapefruit"

The pattern: add intensity, then origin, then specific descriptors. That is the whole skill.

The 21 named faults

This is the BJCP's own fault list, with its own descriptors. Learning to spot even four or five changes how you drink: you stop blaming yourself for not liking a beer that was simply mishandled.

A short history, with the myths marked

Origins. Beer may predate agriculture. It certainly predates most of what we think we know about it, including the story of the IPA.

c. 11,000 BCE

Raqefet Cave, Israel

Stone mortars in a Natufian burial cave, dated 13,700–11,700 years before present, held 121 starch granules from wheat or barley, oat and legumes. The excavators concluded Natufians stored malted seeds and made beer as part of mortuary ritual, several millennia before cereals were domesticated. The authors note the wider "beer drove agriculture" hypothesis remains controversial.

c. 3500 BCE

Godin Tepe, Iran

Jug fragments coated in beerstone give the earliest chemically confirmed barley beer.

c. 3000 BCE

Beer as wages

Workers at Uruk were paid in beer. Labourers on the Great Pyramid at Giza received four to five litres daily. In 2021 a 5,000-year-old beer factory was excavated at Abydos, dated to the reign of King Narmer.

c. 1800 BCE

The Hymn to Ninkasi

A 3,900-year-old Sumerian poem to the goddess of brewing contains the oldest surviving beer recipe, beer made from barley by way of bread. Clay tablets indicate most Mesopotamian brewers were women, and brewing was the only profession under divine protection.

822 CE

Hops enter the record

Abbot Adalard of Corbie writes about hops in beer. Adoption was slow but decisive: unhopped gruit beer spoiled too fast to export, and the alternative, raising alcohol, was expensive. Hops won on economics, not taste.

1516

The Reinheitsgebot

Duke William IV adopts the Bavarian purity law on 23 April. It restricted ingredients to water, barley and hops (yeast is absent, as brewers treated it as process rather than ingredient) and also fixed prices and capped innkeepers' profits. One motive was keeping wheat and rye for bakers so bread stayed affordable.

"Unchanged since 1516" is false. Bavaria allowed coriander and bay leaf by the mid-1500s; wheat beer survived only via an exclusive family privilege. A 1987 European Court ruling struck it down for imported beer, and today it functions essentially as a labelling standard.

1760–1817

Measurement changes everything

Thermometer (1760), hydrometer (1770), improved steam engines (1765). Brewers could finally measure, and pale malt's superior yield reorganised the industry. Wheeler's drum roaster (1817) produced patent black malt.

1842

Plzeň invents golden beer

Bavarian brewer Josef Groll brewed the first batch in Plzeň on 5 October 1842; it was first served on 11 November. Soft Plzeň water, English-style indirectly kilned pale malt and Saaz hops produced a beer that was golden, then a novelty. In Bohemia, lager breweries went from 32.5% of all breweries in 1860 to 97.9% by 1870.

1870

Refrigeration

Carl von Linde built the first large-scale refrigerated lagering tanks for Sedlmayr's Spaten brewery in Munich. Before that, brewers dug ice cellars and planted chestnut trees for shade above them, which is literally where the beer garden comes from.

1883

Pure yeast

Emil Christian Hansen isolates the first pure yeast cell at the Carlsberg Laboratory. All commercial lager yeast descends from it.

1855

Beer arrives in India, commercially

Edward Dyer set up a brewery at Kasauli in the Himalayas, incorporated as Dyer Breweries in 1855 and described as Asia's first. Its brand Lion was originally an India Pale Ale and became a lager only in the 1960s. It led the Indian market from the 1840s to the 1960s, succeeded by Golden Eagle, then Kingfisher from the 1980s. H. G. Meakin bought the Shimla and Solan breweries in 1887; the businesses merged after the First World War and became Mohan Meakin in 1967.

1978–1999

Kingfisher takes over

From United Breweries' own milestones: Kingfisher Premium launched 1978, canned 1981, exported to the UK 1982. Kingfisher Strong launched in 1999 and "soon becomes India's No.1 beer by volume", a fact that tells you a great deal about which way Indian taste ran. Ultra followed in 2009, Ultra Witbier in 2019.

1919–1933

American Prohibition

The Eighteenth Amendment was ratified on 16 January 1919 and Prohibition began in 1920, destroying most American breweries. The Twenty-first Amendment repealed it on 5 December 1933, the only amendment to repeal another.

1971–1980

The craft revival

CAMRA was founded on 16 March 1971, in a bar in County Kerry, Ireland, not England, and reached 5,000 members by 1973. In the US, Fritz Maytag's 1965 rescue of Anchor is the usual turning point; New Albion followed in 1976, homebrewing was legalised in 1978, and Sierra Nevada brewed its first Pale Ale in November 1980. Today an estimated over 40% of US craft beer is IPA.
