Скачать или смотреть What Kind of Roast Has The Most Caffeine?

What kind of roast has the most caffeine? There are so many different views on the roast level and caffeine topic that it becomes confusing to find a definite answer to this seemingly simple question. In this video, I dive deep into the fog of caffeine knowledge and unpack studies, myths, and misconceptions to bring you a conclusive answer to the age-old "roast level and caffeine" question!

The TL:DW answer is that... Third wave light and dark roast coffees have the same caffeine levels. Dark roasts with the First and Second wave methodologies roasted beyond 235°C will have less caffeine.

Hopefully, this answered your question of what kind of roast has the most caffeine! If you disagree with anything said in the video, I encourage you to link me with research that says otherwise, as I am more than willing to change my mind with the proper research!
