New to coffee and this happening confirms my theory on which of the coffees I have are a darker roast. Love the diversity in coffee, thank you for the information!
you mean to say by quantity of beans after roasting dark is more then light is less amount of beans, so how it's possible? please make a video for explain this,..!!
I'll certainly make a video about this, thank you for the suggestion! For quick clarification, what I mean is: when beans are roasted, they lose oil and density. So, darker roasts weigh much less than lighter ones, which is why we usually recommend going by weight and using scales, as opposed to using volumes (cups, tablespoons, etc.) as a measure. Hope that helps!
