Harvesting is currently the biggest limitation to commercial production.
Which points out also the clear market potential if commercial production could be made economically viable. We have on trial, or trialled, about 3 dozen varieties over the past 6 years. The least vigorous with lowest yields for us have been the German Hallertau and Eastern European varieties such as Backa and Elsasser. Saazer, to many the premium hops, is great some years, not in others. It is usually the most precocious, the first ready for harvest.
