The extracted figures from the table are as follows.<\/p><hr class=\"wp-block-separator has-alpha-channel-opacity\"\/><p>Have you ever heard someone say, \u00ab\u00a0Tea has more caffeine than coffee\u00a0\u00bb? When I first heard this, I was half surprised and half skeptical. So, in this article, I will analyze the theory that \u00ab\u00a0tea has more caffeine than coffee\u00a0\u00bb using data.<\/p><p>This time, I referred to the \u00ab\u00a0Standard Tables of Food Composition in Japan, 2020 Edition (8th Revision).\u00a0\u00bb The extracted figures from the table are as follows:<\/p><ul class=\"wp-block-list\"><li>Caffeine content in 100g of coffee extract: 0.06g (Extraction method: 10g coffee powder \/ 150mL hot water)<\/li>\n\n<li>Caffeine content in 100g of gyokuro extract: 0.16g (Extraction method: 10g tea \/ 60\u00b0C 60mL, 2.5 minutes)<\/li>\n\n<li>Caffeine content in 100g of sencha extract: 0.02g (Extraction method: 10g tea \/ 90\u00b0C 430mL, 1 minute)<\/li>\n\n<li>Caffeine content in 100g of kamairicha extract: 0.01g (Extraction method: 10g tea \/ 90\u00b0C 430mL, 1 minute)<\/li>\n\n<li>Caffeine content in 100g of bancha extract: 0.01g (Extraction method: 15g tea \/ 90\u00b0C 650mL, 0.5 minute)<\/li>\n\n<li>Caffeine content in 100g of hojicha extract: 0.02g (Extraction method: 15g tea \/ 90\u00b0C 650mL, 0.5 minute)<\/li>\n\n<li>Caffeine content in 100g of oolong tea extract: 0.02g (Extraction method: 15g tea \/ 90\u00b0C 650mL, 0.5 minute)<\/li>\n\n<li>Caffeine content in 100g of black tea extract: 0.03g (Extraction method: 5g tea \/ 360mL hot water, 1.5 to 4 minutes)<\/li><\/ul><p>This is very interesting data. First of all, it is impressive that the Ministry of Education, Culture, Sports, Science and Technology (MEXT) has classified tea so finely, extracted each type under conditions that bring out the characteristics of their flavor, analyzed the components, and published the results. While it might be easy to think of distinguishing between sencha and black tea, separating and testing sencha and kamairicha shows a deep appreciation for tea from enthusiasts.<\/p><p>Returning to the results, the analysis shows that all teas except gyokuro have less caffeine than coffee. Let\u2019s delve a bit deeper into gyokuro, which has more caffeine than coffee. The extraction method involves using 60mL of water at 60\u00b0C for 2.5 minutes with 10g of tea. This method is known as \u00ab\u00a0shizuku tea,\u00a0\u00bb where the aim is to enjoy the condensed essence of gyokuro. Since the tea leaves absorb water during extraction, the actual amount of extractable liquid is around 20-30mL. This is a very concentrated tea, similar to espresso in coffee terms.<\/p><p>Comparing gyokuro to coffee based on \u00ab\u00a0caffeine content per 100g\u00a0\u00bb creates a discrepancy with practical consumption methods. Comparing \u00ab\u00a0300mL of espresso to 300mL of coffee\u00a0\u00bb feels unrealistic. The special preparation of gyokuro introduces some discomfort in the results.<\/p><p>This data might have led to the theory that \u00ab\u00a0tea has more caffeine than coffee.\u00a0\u00bb The theory is valid if you compare gyokuro (prepared like shizuku tea) in the same quantity as coffee. However, considering typical consumption volumes in daily life, coffee usually has more caffeine. All other<\/p><p>types of tea have less caffeine than coffee.<\/p><p>Therefore, a suitable response to someone saying, \u00ab\u00a0Tea has more caffeine than coffee\u00a0\u00bb would be:<\/p><p>\u00ab\u00a0That\u2019s true for gyokuro. However, comparing gyokuro to coffee is somewhat unrealistic because gyokuro is very concentrated, similar to espresso. You wouldn\u2019t drink 300mL of espresso like you would coffee. When considering the actual amount of caffeine consumed, coffee generally has more. Additionally, all other types of tea have less caffeine than coffee.\u00a0\u00bb<\/p><p>While data is crucial, understanding its context reveals more insights. In this exploration, I felt the Ministry of Education, Culture, Sports, Science and Technology&rsquo;s dedication to tea and their detailed approach was truly impressive. The detailed breakdown and accurate data provided valuable learning.<\/p><p>That\u2019s all for this article. I look forward to analyzing more tea-related theories in the future.<\/p><div class=\"inherit-container-width wp-block-group alignfull is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"wp-block-group__inner-container\"><hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<div class=\"inherit-container-width wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"wp-block-group__inner-container\"><h2 class=\"wp-block-heading has-medium-font-size\" style=\"margin-top:0;margin-right:0;margin-bottom:0;margin-left:0\">\u304a\u3059\u3059\u3081\u8a18\u4e8b<\/h2><\/div><\/div>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-d7d455e7 wp-block-columns-is-layout-flex\" style=\"border-style:none;border-width:0px;border-radius:0px;padding-top:0;padding-right:0;padding-bottom:0;padding-left:0\"><div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.34%\"><figure class=\"wp-block-embed is-type-wp-embed is-provider-teplo wp-block-embed-teplo\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"2Dt4LMXJSI\"><a href=\"https:\/\/teplotea.com\/fr\/teplo-official-tea-nitrogen-package\/\">teplo\u516c\u5f0f\u8336\u8449\u3092\u30d5\u30ec\u30c3\u30b7\u30e5\u306a\u72b6\u614b\u3067\u304a\u5c4a\u3051\u3059\u308b\u305f\u3081\u306e\u5de5\u592b<\/a><\/blockquote><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute;
