History
Hopped beer spreads across northern Europe
Over roughly four centuries hopped beer displaced herb-bittered ale across northern Europe, driven as much by tax and trade as by taste.
1100–1500
The version you have probably heard
“Hops were adopted because brewers discovered they made beer taste better, and unhopped ale simply died out.”
Preservation and trade drove it more than flavour, the shift took centuries rather than happening at once, and it was resisted — in England hopped "beer" and unhopped "ale" were distinguished, separately taxed and separately regarded well into the sixteenth century. Control of gruit was in several places a taxable monopoly, so the change had a fiscal dimension for the authorities as well as a technical one for brewers.
Hop cultivation for brewing is documented in central Europe from the early medieval period and spread north and west over centuries rather than arriving anywhere as an event. Hanseatic trade carried both the hops and the technique.
The advantage was preservation before anyone understood why. Hop compounds have genuine antimicrobial activity against the bacteria that spoil beer, so hopped beer travelled and kept in a way gruit-bittered ale did not — which mattered enormously to anyone brewing for sale rather than for a household.
Why it matters
The single largest change in what beer is made of, and the reason every modern beer style assumes hops rather than a herb blend.
How well this is established

Traditions
- British cask ale — Beer that completes its fermentation in the container it is served from and is dispensed without added gas, at cellar rather than fridge temperature.
- Bavarian lager brewing — Cold fermentation and extended cold storage, developed in Bavarian cellars long before refrigeration and later exported worldwide.
