Myth
‘American Tettnanger is the same hop as German Tettnanger.’
What was grown in the US as 'Tettnanger' was, according to the USDA, originally a mix with Fuggle and later largely Fuggle, an English variety with a different chemistry.
Partly true
‘There are exactly four noble hops.’
There is a well-known list of four, but sources use no fixed definition. According to John Palmer, mainly Hallertauer Mittelfrüh, Tettnanger, Spalter and Saaz are called that; the BJCP uses 'noble' as another word for traditional German or Czech hops.

Terms
- Landrace
- An old variety that does not come from a deliberate cross, but arose through centuries of selection of plants in a region; according to German hop growers, such hop varieties usually have little bittering compound and a good aroma. Examples are Saaz, Hallertauer Mittelfrüh and Tettnanger.
- Protected Geographical Indication (PGI)
- A European protection for a product name that is linked to a region, in which usually at least one step of the production takes place in that region; for beer it applies from 21 October 2026, among others, to 'Vlaams roodbruin bier / Flanders Red Ale'.
- Noble hops
- Name for a group of traditional Central European aroma hops. According to John Palmer, mainly four varieties are called that: Hallertauer Mittelfrüh, Tettnanger, Spalter and Saaz, and their aroma is regarded as the best. The BJCP uses 'noble' as another word for traditional German or Czech hops, which are often subtle, slightly floral, spicy or herbal. The sources give no single definition.
- Farnesene
- One of the heavier aroma compounds in hop oil. Saaz and Tettnanger have a lot of it (about 14–20% or more of the oil), Hallertauer Mittelfrüh and Goldings almost none; such differences in the oil help to tell hop varieties apart chemically.
- Hop oil
- The volatile, fragrant oil from hops (according to John Palmer 0.5–3% of dried hops; some modern varieties are higher, Galaxy according to HPA 2.6–3.3 ml per 100 grams), with compounds such as myrcene, linalool and geraniol; it largely evaporates during the boil, which is why brewers add aroma hops late or dry hop them.
- 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.
