There are a several new hops available on the webstore and they may even be new to you as well. Check out Mosaic, Motueka, Nelson Sauvin, Palisade, Progress, and Topaz online or in the store.
There is a super easy way to get a good feeling for a hop you would like to try out. Try taking a bottle, or can of super light (and relatively tasteless) commercially made beer and add a pellet of the hop you want to try. Give it a bit to breakdown in the beer and give it a taste. You should be able to pick up on the uniqueness of the hop you placed in the beer, and you can make an educated decision on whether you want it in your next homebrew.
