This greatly reduces the likelihood of something going wrong during the drying process, so the coffee is likely to be of a higher quality.  <\/p>\n\n<p>However, this particular process is much more costly than the others.\nAfter harvesting, the coffee is dumped into large pools of water.\nThe unripe coffee cherries, along with various impurities, float to the surface and are evaporated.\nThe outer skin and most of the pulp is then removed using a machine called a &#8216;depulper&#8217;.\nThe coffee is then transferred to a tank of water where the remaining pulp is removed by fermentation.      <\/p>\n\n<p>The pulp contains a lot of pectin and is tightly bound to the grain.\nFermentation, however, sufficiently breaks down the remaining pulp.\nProducers use varying amounts of water during fermentation and there are some environmental concerns about this method, partly due to the eventual amount of waste water which can be toxic, but conscientious producers filter this water before releasing it into the wild.  <\/p>\n\n<p>The length of fermentation depends on several factors including altitude and ambient temperature.\nThe warmer it is, the faster the process will proceed.\nToo long a fermentation can adversely affect the final taste of the coffee.\nThere are many different methods to check when it is appropriate to stop the fermentation process.\nOne way is that the producer puts a wooden stick in the tank and if it stands up, supported by slightly gelatinous water full of pectin, the process is complete.    <\/p>\n\n<p>After fermentation, the coffee is washed.\nThen the coffee is ready for drying.\nThis is usually done in the sun by spreading the coffee out on brick terraces or raised drying tables.\nAs with the natural process, the coffee must be turned regularly using large rakes to ensure slow and even drying.   <\/p>\n\n<p>Many producers of high-quality coffee choose the wet process in an effort to reduce the number of defects in the processing of coffee. However, <a href=\"https:\/\/www.goriffee.com\/shop\/kava\/filter\/kenya-rwegheta-aa-washed\/\">this process<\/a> also has a major impact on the quality of your cup of coffee. Compared to other processes, wet-processed ones have a higher level of acidity and are more complex in flavor, resulting in a much cleaner taste. Purity is a term used in coffee to indicate the absence of negative flavours such as bitterness and astringency.<\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh3.googleusercontent.com\/rn6ZMdXNGK0R-zFYl9lqHsWrTzoedIFS7vs7-ydcmZisDTu5bIvEZKTG_lm1Vr337fWMnafK4fZb7MCeNnGXzx2X27djLRHRBuBqisasQi12Lv1tSNax0fvTRYI-1xsYSOSVFPz2\" alt=\"\"\/><\/figure>\n\n<p><em>&#8220;Removal of peel and parts of the flesh by means of a depulper&#8221;<\/em><\/p>\n\n<h2 class=\"wp-block-heading\">Hybrid processes<\/h2>\n\n<h3 class=\"wp-block-heading\">Pulped natural<\/h3>\n\n<p>This process, which is mainly used in Brazil, is the result of experiments carried out by a manufacturer of coffee processing equipment called Pinhalanse.\nThe aim was to produce high quality coffee using less water than is used in the washed process.\nAfter harvesting, the coffee is mechanically stripped of the top skin and much of the pulp.\nThe coffee is then dried straight on brick terraces or raised beds.\nWith less pulp around the bean, the risk of defects is reduced, yet there is still enough sugar in the residual pulp to bring out the coffee&#8217;s increased sweetness and more pronounced body.\nThis process requires careful drying as well.     <\/p>\n\n<h3 class=\"wp-block-heading\">Honey process<\/h3>\n\n<p>The process is very similar to the previous one.\nIt is used in many Central American countries, including Costa Rica and El Salvador, but you can also find it in <a href=\"\">Rwanda<\/a>, for example.\nThe husk and some of the pulp are also mechanically removed from the coffee, but this method uses even less water than the &#8216;pulped natural&#8217; process.\nPulp removal machines can usually be set up so that a certain percentage of pulp is left around the coffee bean.\nThe resulting coffee is then marked according to how much pulp is left on it.\nFor example, 10% honey or 20% honey and so on.\nIf more pulp is left on the beans, there is a higher risk of fermentation and defects when the coffee is dried.      <\/p>\n\n<h3 class=\"wp-block-heading\">Semi-washed process<\/h3>\n\n<p>In this coffee processing, similar to the washed process, the outer skin is removed from the coffee, the mesocarp (pulp) remains on the parchment (the bottom part of the pulp) and is thus dried in the sun.\nUnlike other processes in which the coffee is dried to 11-12%, the semi-washed process dries the coffee to only 30-35%.\nAfter drying, the coffee is stripped of its pulp and parchment.\nThis is followed by a second drying stage in which the coffee is dried sufficiently so that it is not susceptible to mould or rot.\nAfter the second drying, the coffee acquires the rich dark green colour that is typical of this process.\nThis processing method brings out the body and intensity of the coffee.\nIt is particularly common in Brazilian and Indonesian coffees.      <\/p>\n\n<p>In other blogs, we will look at experimental and exotic processing, as well as processes that can remove caffeine from coffee.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The processing of coffee, or how the husk and pulp are separated from the bean, is one of the most important aspects of coffee cultivation.<br \/>\nHow coffee is processed can have a dramatic effect on the resulting quality and taste.<br \/>\nLet&#8217;s take a look at the most common ways of processing coffee.  <\/p>\n","protected":false},"author":8,"featured_media":16635,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[832],"tags":[],"class_list":["post-42385","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-about-coffee"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/posts\/42385","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/comments?post=42385"}],"version-history":[{"count":0,"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/posts\/42385\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/media\/16635"}],"wp:attachment":[{"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/media?parent=42385"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/categories?post=42385"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.goriffee.com\/en\/wp-json\/wp\/v2\/tags?post=42385"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
