The recent exponential growth of craft beer sector led many brewers to seeking strategies to differentiate their beers from other similar products. For emerging hop-producing countries, one of these strategies relied on the use of local hops, thus taking advantage of the “terroir” effect. This market trend has increased the demand for raw materials from breweries, with positive effects on agricultural production, including hops. However, lack of knowledge along all the hop supply chain heavily hinders the development of a steady and efficient hop production. Particularly, growers urgently need information about the best agronomic practices, which should be adopted to achieve a sustainable hop production, under both conventional and organic farming. Unfortunately, studies on basic hop farming are scarce and often inadequate. The aim of this review is to analyze what agronomic research has done working on hops in the new growing areas (e.g., Brazil, Florida, France, Italy and Virginia) and what it has still to do to facilitate the hop growers in building and conducting their own hopyard. Through this analysis, we also aimed to provide directions for policymakers and scientific community that want to develop a hop supply chain starting from its basis. The review highlighted that while the screening of existing hop commercial cultivars was adequately referenced, the agronomic practices and growing technics suited for each new growing zone are still little studied or completely unknown. The use of artificial LED lighting is a key theme at the lowest latitudes of Florida and Brazil, organic management is pivotal in Italy and France, while alternative trellis design and hop breeding plans represent the shared research interest in all the emerging hop growing zones.

在新种植区发展啤酒花种植：最新技术和前进方向


最近精酿啤酒行业的指数级增长导致许多酿酒商寻求策略，将他们的啤酒与其他类似产品区分开来。对于新兴的啤酒花生产国，其中一种策略依赖于使用当地的啤酒花，从而利用“风土”效应。这种市场趋势增加了对啤酒厂原材料的需求，对包括啤酒花在内的农业生产产生了积极影响。然而，缺乏所有啤酒花供应链的知识严重阻碍了稳定高效的啤酒花生产的发展。特别是，种植者迫切需要有关最佳农艺实践的信息，在传统和有机农业下，应采用这些实践来实现可持续的啤酒花生产。不幸的是，关于基本啤酒花种植的研究很少，而且往往不充分。本综述的目的是分析农艺研究在新种植区（例如巴西、佛罗里达州、法国、意大利和弗吉尼亚州）对啤酒花所做的工作，以及为促进啤酒花种植者建立和经营自己的啤酒花场还需要做什么。通过这项分析，我们还旨在为希望从基础开始发展啤酒花供应链的政策制定者和科学界提供方向。该评论强调，虽然对现有啤酒花商业品种的筛选得到了充分的参考，但适合每个新生长区的农艺实践和种植技术仍然很少被研究或完全未知。人工 LED 照明的使用是佛罗里达州和巴西最低纬度地区的一个关键主题，有机管理在意大利和法国至关重要，而替代棚架设计和啤酒花育种计划代表了所有新兴啤酒花种植区的共同研究兴趣。
