Doppelbock
Doppelbock is a strong, very malty German lager, usually dark and rich in flavour. 'Doppel' means double, but it is not twice as strong as a bock.

What is it?
Myth or fact?
Myth
‘Doppelbock is twice as strong as regular bock.’
'Doppel' means double, but the difference is small: the BJCP gives doppelbock 7–10% and a dark bock 6.3–7.2%. German law sets the same lower limit for both.
Partly true
‘Monks devised doppelbock as liquid bread to get through Lent.’
The story is popular and even appears in the BJCP, but is not proven. Beer writers do call Salvator a beer for a monastery feast, though, and early doppelbocks were heavy and sweet, but not very strong.
Partly true
‘Dutch bokbier is the same as German bock.’
Not necessarily. German bocks are lagers, and in Germany 'Bockbier' must have an original wort content of at least 16% (that is not an alcohol percentage). In the Netherlands above 15% is enough and the fermentation method is free, so there are also top-fermented bokken.
Where does it come from?
How to pour it
A good starting point: 7–10 °C in a tulip glass (advice from CraftBeer.com).

Terms
- Bottom fermentation (low fermentation)
- Fermentation with lager yeast at lower temperatures, in which the yeast sinks to the bottom, as with pilsner and other lagers.
- Lagering
- Letting beer, especially bottom-fermented beer, mature cold for a time after fermentation, so that yeast and proteins can settle and the flavour improves; the word comes from the German 'lagern', to store.
- Mouthfeel / body
- How a beer feels in your mouth: how full or thin it is (the body), how much carbonation it has and whether it is, for example, creamy or rather astringent.
- Original wort (stamwort)
- The wort before fermentation. The extract content of the original wort (in percent or degrees Plato) says how many dissolved substances, mainly sugars, it contains; it is not an alcohol percentage, but it is the legal measure for, among others, pils and bok in the Netherlands and for, among others, Bockbier in Germany.
- Decoction mash (decoction mashing)
- A way of mashing (mixing ground malt with hot water) in which the brewer boils part of the mash separately and returns it to the rest to raise the temperature, sometimes several times; for doppelbock it is traditional.
