Usage tips
Cultural context
Hops are one of the four main ingredients of German beer according to the traditional Purity Law. They are almost always mentioned together with 'Malz' (malt), the other important plant-based ingredient.
EXAMPLE
Für gutes Bier braucht man nur Wasser, Malz, Hopfen und Hefe.
For good beer, you only need water, malt, hops, and yeast.
Fixed expression
The idiom 'Bei jemandem/etwas ist Hopfen und Malz verloren' (someone/something is a lost cause) is fixed and unchangeable. It expresses that all effort is in vain and a situation or person can no longer be saved.
EXAMPLE
Er will einfach nicht lernen. Ich glaube, bei ihm ist Hopfen und Malz verloren.
He simply doesn't want to study. I think he is a lost cause.
Context clue
You can always recognize the idiomatic meaning from the complete phrase 'Hopfen und Malz verloren' (a lost cause). If 'Hopfen' (hops) is used alone or in the context of agriculture, brewing, or beer, it refers to the plant.
EXAMPLE
Der Bauer erntet den Hopfen im Spätsommer.
The farmer harvests the hops in late summer.
Use as a mass noun
When 'Hopfen' (hops) refers to the brewing ingredient, it is usually used as an uncountable noun, or mass noun. It then often appears in the singular without an article.
EXAMPLE
Dieses Bier enthält besonders viel Hopfen und schmeckt daher sehr bitter.
This beer contains especially a lot of hops and therefore tastes very bitter.

Hopfen vs Hefe
yeast
'die Hefe' and 'der Hopfen' can easily be confused because both play a role in food and especially in beer. But they are completely different things. 'Hefe' is a fungus that makes dough rise and helps with fermentation, for example in beer or wine. 'Hopfen' is a plant whose flowers give beer flavor and bitterness. In baking, you normally need yeast, not hops. In brewing beer, both can occur, but with different roles: yeast provides fermentation, hops provide aroma.
Hopfen
Zum Brauen von Bier gibt Hopfen dem Getränk seinen bitteren Geschmack.
When brewing beer, hops give the drink its bitter taste.
Hefe
Für den Pizzateig brauchst du Hefe, damit er schön aufgeht.
For the pizza dough, you need yeast so that it rises nicely.
