I am going to brew an IPA today and I'm out of Cascade hops (I was going to use them for bittering.) I have Amarillo, Mt Hood, Kent Golding, and Chinook. Anybody have a sugestion on what one would make the best substitute.
Thanks

Amarillo is a good substitution for Cascades. Like Cascades it has a nice citrusy aroma.

By the way, a good source of information regarding hops and hop substitutions is Hopunion's databook which may be found at: http://www.hopunion.com/hopunion-variety-databook.pdf

This is a very good source of information.

The only problem I have with their information is that they suggest German varieties as substitutions for U.S. Tettnang. However, chemical analysis of essential hop oils indicate that U.S. Tettnang is virtually idential to Fuggle hops and not German Tettnang. Apparently either purposely or accidentally Fuggle hops were planted instead of the Tettnang variety in the U.S. The same can also be said of Styrian Goldings. Styrian Golding hops are nothing like Kent Goldings; they are essentially Fuggle hops. Although there is likely some variation with respect to the growing region in both cases Fuggle and Willamette are probably the best substitutions.

So I seem to have gotten of topic here (sorry about that).

At any rate, I hope this helps!
