Earlier this year, the giant multinational conglomerate Nestl\u00e9 unveiled the\u00a0<a rel=\"noreferrer noopener\" href=\"https:\/\/www.nestleprofessional.com\/beverage\/roastelier\" target=\"_blank\">Roastelier<\/a>, a counter-top roaster designed for cafes and baristas. Nestl\u00e9 calls it \u201ca compact coffee-roasting solution that will allow baristas to unlock and simplify the art of roasting in the shop.\u201d<\/p>\n\n\n\n<iframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/xWQ91qAR0Bk\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"><\/iframe>\n\n\n\n<p class=\"has-small-font-size\"><em>Nestl\u00e9&#8217;s Roastelier<\/em><\/p>\n\n\n\n<p>While home roasters like the&nbsp;<a target=\"_blank\" href=\"https:\/\/sonofresco.com\/\" rel=\"noreferrer noopener\">Sonofresco<\/a>,&nbsp;<a target=\"_blank\" href=\"https:\/\/behmor.com\/\" rel=\"noreferrer noopener\">Behmor<\/a>,&nbsp;<a target=\"_blank\" href=\"https:\/\/www.hottopamericas.com\/\" rel=\"noreferrer noopener\">Hottop<\/a>, and&nbsp;<a target=\"_blank\" href=\"https:\/\/www.sweetmarias.com\/roasting\/air-roasters\/freshroast.html\" rel=\"noreferrer noopener\">Fresh Roast<\/a>&nbsp;have been around for years, the success of the&nbsp;<a target=\"_blank\" href=\"https:\/\/www.ikawacoffee.com\/\" rel=\"noreferrer noopener\">IKAWA<\/a>&nbsp;seems to have opened the floodgates for this latest round of digitization. The IKAWA is the first digital micro-sample roaster containing the ability to control graphs and profiles from your phone\u2014and this innovation has spurred advancements in the market.&nbsp;<a target=\"_blank\" href=\"https:\/\/bellwethercoffee.com\/\" rel=\"noreferrer noopener\">Bellwether<\/a>, an all-electric ventless roaster, recently raised $40 million in its Series B round of financing, showing that innovation is taking place and that others are interested in jumping on board.&nbsp;<\/p>\n\n\n\n<p>Most of these digital roasters are designed for sample roasting, but they can also be used by home roasters and baristas looking to roast coffee on their own.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Digital Roasters Can Help Efficiency &amp; Accessibility<\/h3>\n\n\n\n<p>Like most technology, digitizing sample roasters was based on a need: creating consistent, hands-free roasting of multiple samples or batches of coffee. Whereas before, a coffee roaster might have to stand over a manual drum and watch every step of the roasting process, now, anyone can select a profile, push a button, and walk away. It comes down to efficiency\u2014the ability to simultaneously sample roast new coffees and also roast coffee for production.<\/p>\n\n\n\n<p>Geoff Woodley, head of marketing for IKAWA, also notes that digital roasters make sample roasting more accessible.<\/p>\n\n\n\n<p>\u201cIt was a major gap in the sample roasting world for people to know what a good sample roast was and how to achieve it,\u201d he says. \u201cWe encountered a lot of producers who thought they couldn\u2019t roast. The IKAWA makes it really concise and really simple.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"817\" height=\"1024\" src=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/IKAWA_DavidBowden-817x1024.jpg\" alt=\"\" class=\"wp-image-29397\" srcset=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/IKAWA_DavidBowden-817x1024.jpg 817w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/IKAWA_DavidBowden-399x500.jpg 399w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/IKAWA_DavidBowden-768x962.jpg 768w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/IKAWA_DavidBowden-200x251.jpg 200w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/IKAWA_DavidBowden-239x300.jpg 239w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/IKAWA_DavidBowden.jpg 1015w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption>The IKAWA roaster. Photo by David Bowden.<\/figcaption><\/figure>\n\n\n\n<p>Of course, other larger commercial roasters, such as the&nbsp;<a target=\"_blank\" href=\"https:\/\/loring.com\/\" rel=\"noreferrer noopener\">Loring<\/a>, have been automated and digital for a few years, but not in a way that was accessible to non-professional roasters. Newer, digital roasters are not just for \u201cprofessional\u201d roasters anymore; coffee farmers and consumers can now roast easily.<\/p>\n\n\n\n<p>But digital roasters also provide an added benefit to professionals: it\u2019s all about time and manual labor. With a digital roaster, one could roast just as fast as traditional roasters but quickly manage multiple samples. Sample roasting, or roasting small batches of coffee usually to make purchasing decisions, can require a lot of monotonous hands-on time that a roaster could spend more productively.&nbsp;<\/p>\n\n\n\n<p>But that\u2019s not the only reason for the creation of these machines.<\/p>\n\n\n\n<p>Andrew Stordy, an engineer and industrial designer by trade, founded IKAWA while living abroad. As he traveled through coffee-producing countries like Burundi (the name IKAWA is from the word for \u201ccoffee\u201d in Kirundi, the official language of Burundi), he noticed a massive gap between coffee producers and coffee consumers: many producers were not able to drink the coffee they grew. These simple, compact digital roasters make it much easier for producers to roast and drink their coffee.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Not Just Air Roasters<\/h3>\n\n\n\n<p>Most of these new digital roasters are \u201cair\u201d or \u201cfluid bed\u201d roasters, using hot air to roast coffee, unlike more traditional \u201cdrum\u201d roasters that hold coffee in a drum as it rotates over a heat source. Some companies, however, like&nbsp;<a target=\"_blank\" href=\"https:\/\/freshcup.com\/the-five-tools-we-loved-at-the-2022-specialty-coffee-expo\/\" rel=\"noreferrer noopener\">Aillio<\/a>&nbsp;and&nbsp;<a target=\"_blank\" href=\"https:\/\/www.roestcoffee.com\/\" rel=\"noreferrer noopener\">ROEST<\/a>, are applying automated digital technology to both types of roasters.<\/p>\n\n\n\n<p><a target=\"_blank\" href=\"https:\/\/hoos.coffee\/\" rel=\"noreferrer noopener\">Rob Hoos<\/a>, Portland, Oregon-based author, roaster, and director of coffee at&nbsp;<a target=\"_blank\" href=\"https:\/\/www.nossacoffee.com\/\" rel=\"noreferrer noopener\">Nossa Familia Coffee<\/a>, says they roast on a combination of sample roasting machines:<\/p>\n\n\n\n<ul><li>Two IKAWAs (digital fluid bed)<\/li><li>An Ambex 1 Kilo (manual drum)<\/li><li>A U.S. Roaster Corp (manual drum)<\/li><\/ul>\n\n\n\n<p>He also teaches a class through the Specialty Coffee Association (SCA) on sample roasting using a home roaster, the Aillio Bullet R2 1 kilo (digital drum). Of the rise in digital roasting, he believes that it could be partially due to a dislike of the process of sample roasting.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"580\" src=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Roest_1015-1024x580.jpg\" alt=\"\" class=\"wp-image-29400\" srcset=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Roest_1015-1024x580.jpg 1024w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Roest_1015-500x283.jpg 500w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Roest_1015-768x435.jpg 768w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Roest_1015-200x113.jpg 200w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Roest_1015-530x300.jpg 530w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption>The ROEST digital sample roaster. Photos courtesy of ROEST<\/figcaption><\/figure>\n\n\n\n<p>Norway-based ROEST combines the best of both roasting worlds: a small digital roaster utilizing a conventional drum design. \u201cWhen we started, drum roasters were the baseline. They were durable and manual,\u201d says ROEST CEO and cofounder Trond Simonsen.<\/p>\n\n\n\n<p>\u201cConsistency was, however, a problem,\u201d he continues. \u201cAfter IKAWA managed to open up the market for digitalization, everything has changed. Now we are first asked if we are digital, then if you can roast manual [using our machines]. A lot of our customers want the best from both worlds\u2014and that\u2019s been a key principle in our development.\u201d<\/p>\n\n\n\n<p>\u201cWe\u2019re teaching our roasters to listen for the sound of first crack to take consistency and automation to the next level,\u201d adds Trond\u2019s brother, Sverre Simonsen, the engineer and cofounder of ROEST. He refers to a point in the coffee roasting process where heat causes beans to expand and make a notable \u201cpopping\u201d sound.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1015\" height=\"761\" src=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Windelboe_Roest_1015.jpg\" alt=\"\" class=\"wp-image-29402\" srcset=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Windelboe_Roest_1015.jpg 1015w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Windelboe_Roest_1015-500x375.jpg 500w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Windelboe_Roest_1015-768x576.jpg 768w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Windelboe_Roest_1015-200x150.jpg 200w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Windelboe_Roest_1015-400x300.jpg 400w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption>Tim Wendelboe has been using ROEST for quality control, sample roasting for buying, and roasting classes for the past year.

The machine can be used to roast manually, semi-automatically, or fully autonomously. They note that different companies employ its use differently. \u201cROEST is designed not only to complement a traditional drum roaster, but to replace it,\u201d says Trond.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Future of Traditional Roasters<\/h3>\n\n\n\n<p>The question lingers: As digital roasters, which mainly use air roasting technology, become more popular, will air roasting replace drum roasting as the method of choice for sample roasting?<\/p>\n\n\n\n<p>\u201cI think it can,\u201d says Marcus Young of&nbsp;<a target=\"_blank\" href=\"https:\/\/bootcoffee.com\/\" rel=\"noreferrer noopener\">Boot Coffee<\/a>. \u201cWith more and more roasters using IKAWA sample roasters or Stronghold roasters, and even production roasting with Loring Roasters with their highly convective heat, fluid bed may be the way to go.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1015\" height=\"571\" src=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/MarcusYoung_BOOT_1015.jpg\" alt=\"\" class=\"wp-image-29404\" srcset=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/MarcusYoung_BOOT_1015.jpg 1015w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/MarcusYoung_BOOT_1015-500x281.jpg 500w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/MarcusYoung_BOOT_1015-768x432.jpg 768w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/MarcusYoung_BOOT_1015-200x113.jpg 200w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/MarcusYoung_BOOT_1015-533x300.jpg 533w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption>Marcus Young. Photo courtesy of Marcus Young\/Boot Coffee<\/figcaption><\/figure>\n\n\n\n<p>He also notes that roasters offer improved control over heat and airflow compared to traditional sample roasters. \u201cWith the IKAWA, I can send a profile to the roaster and have a lab assistant roasting samples with about ten minutes of training,\u201d says Young. \u201cI\u2019ve also found the ability to develop and share profiles on fluid bed machines to be appreciated by my clients who operate roasting companies.\u201d<\/p>\n\n\n\n<p>But Phil Beattie of&nbsp;<a target=\"_blank\" href=\"https:\/\/www.dillanos.com\/\" rel=\"noreferrer noopener\">Dillanos Coffee Roasters<\/a>&nbsp;in Sumner, Washington, disagrees.<\/p>\n\n\n\n<p>\u201cI do not think air roasting will replace drum sample roasters,\u201d he says. \u201cAir roasting imparts a very specific development of flavor in a way that favors certain core profiles. My experience is that air roasting requires additional roast variance to bring out the flavors of natural and honey processed coffees. This required variance for air roasting introduces new variables that are not necessarily present in drum roasting. Sample roasting aims to limit variables and create uniformity of sample assessment worldwide.\u201d<\/p>\n\n\n\n<p>Yimara Martinez Agudelo is a quality control specialist at&nbsp;<a target=\"_blank\" href=\"https:\/\/www.sustainableharvest.com\/\" rel=\"noreferrer noopener\">Sustainable Harvest<\/a>. Agudelo roasts on two IKAWAs and a Probat (a drum roaster) and has developed a profile similar to that of a drum roaster by cupping two roasts (one from the drum roaster and one from the IKAWA) side by side to achieve the same expression of flavor and smell for quality control purposes.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Yimara_New-768x1024.jpg\" alt=\"\" class=\"wp-image-29406\" srcset=\"https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Yimara_New-768x1024.jpg 768w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Yimara_New-375x500.jpg 375w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Yimara_New-200x267.jpg 200w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Yimara_New-225x300.jpg 225w, https:\/\/freshcup.com\/wp-content\/uploads\/2020\/08\/Yimara_New.jpg 1015w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption>Yimara Martinez Agudelo with an IKAWA roaster. Photo courtesy of Sustainable Harvest<\/figcaption><\/figure>\n\n\n\n<p>Even if drum roasters remain the choice of importers and large companies, smaller digital roasters seem perfect for small- to medium-sized roasting companies for both their price and quality.<\/p>\n\n\n\n<p>As digital roasting technology develops, that doesn\u2019t mean there aren\u2019t benefits of learning how to manually roast: what better way to get a feel for roasting coffee than a hands-on approach? \u201cThere are certain things I appreciate about manual roasting that are not easy to replace,\u201d says Rob Hoos. \u201cLike if you have the same person doing both sample roasting and production roasting, you get a better feel for the coffee.\u201d<\/p>\n\n\n\n<p>With that in mind, it\u2019s still too early to tell whether these digital machines will one day take over coffee roasting completely. But the future of coffee roasting, in general, is headed in this technical direction\u2014a digital, autonomous frontier. As Trond says, \u201cIt\u2019s about time.\u201d<\/p>\n\n\n\n<p>The machines are here to stay.<\/p>\n\n\n\n<p><em>Cover photo courtesy of IKAWA<\/em><\/p>\n\n\n\n<p><em>This article was originally published on August 25, 2020, and has been updated to reflect Fresh Cup&#8217;s editorial standards. <\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the last five years, we\u2019ve seen a giant leap in one very specific aspect of roasting technology: the rise of smaller, more compact digital roasters.<\/p>\n","protected":false},"author":1513,"featured_media":29392,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"limit_modified_date":"","last_modified_date":"","jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_newsletter_tier_id":0,"footnotes":"","jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","enabled":false}},"beyondwords_generate_audio":"","beyondwords_project_id":"","beyondwords_content_id":"","beyondwords_player_style":"","beyondwords_language_id":"","beyondwords_title_voice_id":"","beyondwords_body_voice_id":"","beyondwords_summary_voice_id":"","beyondwords_error_message":"","beyondwords_disabled":"","beyondwords_podcast_id":"","beyondwords_hash":"","publish_post_to_speechkit":"","speechkit_hash":"","speechkit_generate_audio":"","speechkit_project_id":"","speechkit_podcast_id":"","speechkit_error_message":"","speechkit_disabled":"","speechkit_access_key":"","speechkit_error":"","speechkit_info":"","speechkit_response":"","speechkit_retries":"","speechkit_updated_at":"","_speechkit_link":"","_speechkit_text":""},"categories":[14249,23],"tags":[],"jetpack_publicize_connections":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.12 -
