Read screen size, moisture and defect limits alongside the assessment method and sample record. A grade name does not replace physical assessment and tasting for the intended use.<\/p>\n<nav aria-label=\"In this guide\">\n<ul>\n<li><a href=\"#guide-section-1\">What does a screen-size specification describe?<\/a><\/li>\n<li><a href=\"#guide-section-2\">Read moisture, defects and foreign matter together<\/a><\/li>\n<li><a href=\"#guide-section-3\">Separate processing information from sample results<\/a><\/li>\n<li><a href=\"#guide-section-4\">Choose the specification for a supplier discussion<\/a><\/li>\n<\/ul>\n<\/nav>\n<h2 id=\"guide-section-1\">What does a screen-size specification describe?<\/h2>\n<p>Screen size describes a bean-size classification. When comparing S13, S16 or S18, also ask about screen retention, tolerance and the assessment method. Screen size alone does not establish the coffee\u2019s sensory quality.<\/p>\n<h2 id=\"guide-section-2\">Read moisture, defects and foreign matter together<\/h2>\n<p>Record the unit, limit and method for each attribute. Clarify the definitions of black beans, broken beans and foreign matter so specification sheets can be compared. Confirm that the published limits apply to the proposal and lot being discussed.<\/p>\n<ul>\n<li>Screen size and retention.<\/li>\n<li>Moisture and its measurement method.<\/li>\n<li>Defect and foreign-matter definitions.<\/li>\n<li>Sample reference and assessment results.<\/li>\n<\/ul>\n<h2 id=\"guide-section-3\">Separate processing information from sample results<\/h2>\n<p>Ask the supplier to describe the process used and provide related records where needed. Then assess the sample with an agreed method. A processing label does not by itself confirm flavour or suitability for the buyer\u2019s roasting approach.<\/p>\n<h2 id=\"guide-section-4\">Choose the specification for a supplier discussion<\/h2>\n<p>Use Vinh Hiep\u2019s Robusta product pages to compare the published specification fields. Send the product name, requested attributes and sample questions to the team. Keep your assessment results separately as a basis for discussing any specification changes.<\/p>\n<section id=\"faq\">\n<h2>Frequently asked questions<\/h2>\n<h3>Does a larger screen always mean better flavour?<\/h3>\n<p>Sensory quality cannot be determined from screen size alone. Assess the sample for the intended use.<\/p>\n<h3>Does a website specification replace lot confirmation?<\/h3>\n<p>No. Confirm the specification fields and records that apply to the proposal being discussed.<\/p>\n<\/section>\n<aside class=\"vh-guide-links\">\n<h2>Continue your buying review<\/h2>\n<ul>\n<li><a href=\"https:\/\/vinhhiepgl.com\/en\/gia-lai-coffee-origin-guide\/\">Gia Lai coffee export: origin records for buyers<\/a><\/li>\n<li><a href=\"https:\/\/vinhhiepgl.com\/en\/green-coffee-sample-evaluation\/\">Green coffee sample evaluation: a buyer\u2019s record<\/a><\/li>\n<li><a href=\"https:\/\/vinhhiepgl.com\/en\/coffee-sourcing-buyer-guide\/\">Vietnam coffee supplier: a sourcing guide for buyers<\/a><\/li>\n<li><a href=\"https:\/\/vinhhiepgl.com\/en\/sustainable-coffee-buyer-verification\/\">Sustainable coffee sourcing: checking records and scope<\/a><\/li>\n<li><a href=\"https:\/\/vinhhiepgl.com\/en\/san-pham\/robusta-grade-1-s13-standard\/\">Robusta S13 Standard specification<\/a><\/li>\n<\/ul>\n<\/aside>\n<p><a class=\"button secondary\" href=\"https:\/\/vinhhiepgl.com\/en\/contact-us\/\">Send Vinh Hiep your product requirements<\/a><\/p>\n<p class=\"vh-guide-source\">Reference for further review: <a href=\"https:\/\/sca.coffee\/value-assessment\" target=\"_blank\" rel=\"noopener\">SCA Coffee Value Assessment<\/a>.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Read Vietnamese Robusta specifications: screen size, moisture, defects, processing information and the questions to confirm when selecting samples.<\/p>\n","protected":false},"author":1,"featured_media":1338,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[17],"tags":[],"class_list":["post-1961","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-events"],"acf":[],"_links":{"self":[{"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/posts\/1961","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/comments?post=1961"}],"version-history":[{"count":4,"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/posts\/1961\/revisions"}],"predecessor-version":[{"id":2069,"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/posts\/1961\/revisions\/2069"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/media\/1338"}],"wp:attachment":[{"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/media?parent=1961"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/categories?post=1961"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vinhhiepgl.com\/en\/wp-json\/wp\/v2\/tags?post=1961"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
