What are the disadvantages of using hop cone hops?

The correct choice highlights that using hop cone hops can lead to more oxidation and wort loss compared to other forms of hops, such as pellets or extracts. Hop cones are bulkier and have a greater surface area exposed to air when added to the brew. This increased exposure can lead to faster oxidation of the hops, which negatively affects their aromatic and flavor characteristics. Additionally, whole hop cones can absorb more wort, which can result in a reduction of extractable sugars, thereby impacting the overall efficiency of the brewing process.

In summary, while whole hop cones might offer a traditional and potentially aromatic experience, their physical characteristics pose challenges such as increased oxidation and wort retention, both of which can affect the final product's quality and yield.
