The trend for almost five years has been less bitter IPAs. IPAs are still the hottest trend in craft beer, but the days of one-upmanship in bitterness stopped around the time Heady Topper gained prominence. Subsequently there was a rise in "session IPAs" - usually about 5% ABV and 45 IBUs. In the last two years, the most hyped style has been the New England IPA. All the hop aroma of yesterday's 100 IBU Double IPA but with half the bitterness.
