Anything English well work well.
Not in this house! I use a combo of German and American hops....usually Tettnang and Cascade.
Likewise here...I use English, American, and Czech varieties as a rule (mostly American...I almost always have Cluster and Bullion in the freezer).
The bigger rule is I use whatever I have on hand
. It rarely makes a noticeable difference, at least not in the porters, anyway.
