Prefacing Friday’s samplings of Half Acre Gone Away IPA and Around the Bend “Ghost of ‘lectricity” Kolsch was a beer-concerned quiz. Here are the questions:
- Name the two basic beer styles.
- What are the two styles of hops?
- What has most influence on an IPA’s flavor?
- Kölsches are _______- style beers?
The answers are:
- Ale and Lager
- Ales are top-fermented, meaning yeast cells rise to the top of the warm mash and infuse it with flavor that melds into it via gravity. By contrast, lagers are largely cold-fermented, confining yeasts to the vat bottom, where infusion occurs slowly due to the mash’s colder temperature.
- Bitter and Aromatizing
- Length of time hops are left in the mash
- Certain IPA recipes ask for bitter hops to remain in the mash for days before it is finished with aromatizing and/or bitter hops.
- Kölsches are Ales
(a) Initially top-fermented, kölsches are then cold-stabilized to allow slow development of flavor.
