So, from a guy who has a hop contract I can tell you that right now and next year there look to be plenty of some hops: Centennial for instance. It's amazing how many centennials are still on the market even now. In fact, there are left over centennials all the way back to 2011. The scary shortages are things like magnum. We were not able to increase our contract next year for magnum. Or Crystal (which really suck because I love that hop.)
But apparently there are enough centennials going around so hoppy centennial beers are here to stay for a while.
