English Corner | 生豆的储藏(一)
Until recent years, all coffee was packaged in burlap(jute) snacks and shipped in containers, arriving at roasters months after the coffee was processed. Roasters and importers frequently had the experience of cupping a coffee at origin, or perhaps cupping and approving a “pre-shipment sample”, only to recieve coffee ruined by exposure to poor atmospheric condictions in storage or transit in .

直到近几年,所有的咖啡豆都是用麻袋包装,用集装箱进行运输的,在咖啡豆经处理后的几个月才能到达烘焙商。烘焙商和进口商如果偶尔想要杯测来自原产地的咖啡豆,或者是品尝一下“运货前的样本”,收到的却会是被储藏或运输中糟糕的大气环境毁坏了品质的咖啡豆。

In the past ten years, several small, quality-driven roasters have spearheaded a revolution in green-coffee packaging and transport. Many roasting companies and, even some of the smallest ones, now buy coffee directly from farmers, share cupping and green-grading information with the farmers and demand speedy delivery of coffee in packaging designed to perserve its freshness and quality. Such packaging is costly but justified, given the ever-increasing premiums paid for specialty coffees.

过去的十年里,一些小型的、追求品质的烘焙商先做出了尝试,改变了生豆包装和运输方式。许多的烘焙公司,即使是一些最小的,现在都是直接从种植民的手中直接购买咖啡豆,与农民分享杯测和豆子评级的信息,并使用更快的运输方式,以及特殊设计的能保存豆子新鲜度和质量的包装方式。这些包装会很贵,但考虑到精品咖啡的价格在持续增长,这些运费也还是合理的。

The following is the survey of the more prominent packaging options:

下面列举的是调查显示的最常用的包装方式:

Burlap(jute)bags are the most common and economical optition for packaging and transporting green coffee. Jute is a renewable resource, and the bags are cheap;their use requires no special skills or equipment beyond those that are standard at any dry mill or exporting operation. Burlap sacks do not protect coffee from moisture or odors, however, so the coffee is vulnerable to damage during transport and storage.

麻袋是包装和运输生豆最常用也是最经济实惠的选择,黄麻是可再生资源,而且麻袋很便宜,使用起来也不需要超出一般磨坊和出口点能力的特殊技能或器械。但是,麻袋无法隔绝湿气与臭味,因此其转的咖啡豆在储藏和运输的过程中很容易受到损坏。

Vacuum sealing is the best availale packaging for green coffee. Vaccum-sealed bags protect beans from moisture, odors, and oxygen, dramatically slowing the respiration and therefore the aging of green coffee. Before vacuum sealing, care must be taken to measure beans' water activity to prevent development of mold during storage. Vacuum packaging costs approximately USD 0.15-0.25 per pound (EUR 0.45-0.75 per kilogram), reauires special equipment and skill to implement, and often delays shipment of green coffee, so it is not without its costs and risks.

真空包装是生豆包装最好的方法,真空袋能使生豆隔绝湿气、臭气和氧气,并能大大的减慢呼吸过程,因此减慢咖啡豆的老化过程。在将生豆装进真空袋之前,要密切关注豆子的水分活性,避免在储藏期的生豆发霉。真空包装的成本将近每磅0.15-0.25美元(没公斤0.45-0.75欧元),并且需要特殊的机器以及技能,通常还会延误生豆的运输时间,因此这种方式还是不无成本与风险的。
