Chinook
Chinook is an American hop from the American government's breeding programme, on the market since the mid-1980s. At first mainly a bittering hop, it is now also appreciated for pine, grapefruit and spicy notes.

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
- 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.
- 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.
- Super-alpha hop
- A trade term for hop varieties with an exceptionally high alpha acid content, such as Columbus, Tomahawk and Zeus (about 14–18%); according to the USDA, the trade also counted Chinook among them. They are mainly used to give beer bitterness.
