The thing about caffeine and light/dark roast is controversial.
If you measure the same volume of ground beans light vs dark to make your coffee it’s true. But that’s largely just because the darker beans are a lower density. You’re actually using less coffee with the dark roast.
If you’re measuring your coffee with a scale as a lot of enthusiastic coffee people do you don’t get this effect.
When you’re filling an espresso porta filter the density difference can be pretty noticeable. Say I weigh 15g of beans, with a dark roast the basket is 3/4 full, with a light roast maybe it’s 1/2 full.
Scotch and Whiskey and Wine obviously have all these fascinating aspects too just like beer and coffee. But tea might actually be the most fascinating of all of them. There can be really staggering differences in taste between the different variations of “plain tea”.
