Myth or fact?
Partly true
‘The more hops there are in a beer, the longer it keeps.’
Hops do inhibit some of the bacteria that spoil beer, that is correct. But not all beer spoilers, and the hop aroma itself is fragile: strongly hopped beers are best drunk fresh and stored cool.

Terms
- Thiols
- Sulfur compounds that you can smell at just a few to a few dozen nanograms per litre, such as 4MMP (blackcurrant, passion fruit) and 3MH (rhubarb, grapefruit); they come from hops and also from malt, often in a bound form from which yeast can release them during fermentation.
- Alpha acids
- The main bitter compounds from hops (humulones); they dissolve poorly and are hardly bitter, but during the boil they turn into iso-alpha acids, which do taste bitter.
- Dry hopping
- Adding hops after the wort has been boiled, often during or after fermentation, mainly for a fresh, strong hop aroma.
