What is the primary purpose of using aged hops in Lambic?

• A. To increase bitterness
• B. To provide antibacterial properties
• C. To aroma fermentation
• D. To darken the beer

Answer: (B)

The key idea is that hops in Lambic mainly act as a preservative through their antimicrobial properties. Aging the hops reduces their bitterness, which suits Lambic’s low-bitter, highly complex profile, but the antimicrobial compounds—especially those from the hop resins—still help inhibit spoilage-causing microbes during the long, open-fermentation and barrel-aging process. This helps create a more stable environment for the wild yeasts and bacteria that drive Lambic’s unique fermentation, rather than aiming to increase bitterness, add aroma, or darken the beer.
