Step 1: Understanding the Concept:
Brewing technology utilizes female flowers of the hop plant (Humulus lupulus) as an essential raw ingredient.
Step 2: Detailed Explanation:
In brewing ale and lager beers, hops are added during the wort boiling stage.
Hop resins (alpha-acids such as humulone) isomerize into iso-alpha-acids, imparting characteristic bitterness, floral/herbal aroma from hop essential oils, foam stability, and natural antimicrobial preservation against Gram-positive bacteria.
Step 3: Final Answer:
Thus, hops are used in the manufacturing of ale beer.
