Black Insomnia Coffee from South Africa now claims to have the “world’s strongest cup of coffee.” Black Insomnia utilizes robusta beans that have the highest levels of caffeine. With at least 702mg of Caffeine per 12 fl. Oz Cup they are 6.3% much stronger than the current strongest coffee.
This coffee must be used with caution and only by individuals who have a high threshold to caffeine. Only one 12 fl oz cup is nearly double the suggested safe daily dose of coffee the healthy adult should take. Even though this brand began in South Africa, it will likely be included in the Europe, US, and Australia soon.
