Beer through time
Myths, examined
Beer history carries an unusual density of confidently repeated claims that do not survive the sources — largely because much of the popular account was written as marketing and then recycled by writers with no reason to doubt it.
Why the verdicts are not just true and false
The commonest failure in this genre is the confident debunk: taking a claim that is half right and announcing it is false, which replaces one wrong belief with another. The IPA story is the standard example — the beer really did go to India, and it is the causal claim wrapped around that fact which fails.
So there are six verdicts. One of them is no evidence either way, which is deliberately not the same as false: a claim nobody has produced evidence for has not been disproved, and saying so is more honest than the alternative. Every page also has to state what is worth keeping, because a correction that leaves a reader with less than they arrived with is not an improvement.
Not true
The evidence contradicts it.
- Was lager invented in 1842?
Cold bottom-fermented brewing is centuries older than 1842. What was new at Plzeň was a lager that was pale and clear, which is a combination rather than an invention.
- Did Pasteur discover yeast?
Yeast was under a microscope two centuries earlier. Pasteur established that fermentation is biological — a harder claim, and the foundation of brewing microbiology.
- Was historical small beer an early alcohol-free beer?
Small beer was weak, not alcohol-free — typically one to three per cent, made by reusing spent grain. No modern alcohol-free threshold would come close to permitting it.
Misleading
The underlying facts are roughly right; the conclusion drawn from them is not.
- Did people drink beer because the water was unsafe?
Medieval people drank water routinely and wrote about it. Ale was food, sociability and trade — safety was the reason only where the water was visibly foul.
- Was IPA invented so beer could survive the voyage to India?
Pale ale really went to India and hops really preserve beer. No style was invented for the voyage, porter made the trip fine, and the name arrived decades later.
- Has the Reinheitsgebot protected German beer unchanged since 1516?
A real 1516 Bavarian ordinance, listing three ingredients, concerned with bread grain and prices, replaced repeatedly since. The modern rules are twentieth-century law.
Partly true
Holds in some places or periods and has been generalised well beyond them.
- Is stout just a strong porter?
Historically exact — stout was an adjective meaning strong. As a description of the two words today it is wrong, and modern dry stout is often the weaker of the pair.
- Was beer stronger in the past?
True for twentieth-century Britain, where wartime tax and grain policy cut strength for good. Not true generally — most historical beer by volume was weak.
Genuinely contested
Credible sources disagree, and BeerHQ presents the disagreement rather than picking a winner.
No evidence either way
Nobody has produced evidence for it. That is not the same as it having been disproved.
