>Drip coffee has even more than espresso.

Only if you also think that beer has more ethanol in it than whisky.

In equal quantities, neither is true.

>Drip coffee has even more than espresso [in typical serving sizes].

FTFY.

You need 4 shots of espresso to match the caffeine in 16oz of drip coffee. This does depend on roast; darker roasts have less.

A 16oz or 20oz latte at Starbucks will have 2 shots, i.e. medium roast drip is double, and even a standard 16oz americano at Starbucks only has 3 shots; drip still has 33% more.

Flat Whites are trickier, because despite having an extra shot over lattes (3 in 16oz/20oz), the shots are ristretto (less water), which extract less caffeine.

For those interested, Starbucks publishes caffeine content of all their drinks, which makes a nice baseline for comparison.

A 'tall' filter coffee, which IIRC is 16oz in the US, is 229mg, about equivalent to 3 single espresso shots (page 4 of the link below).

Short, Tall, Grande, Venti => 8oz, 12oz, 16oz, 20oz respectively.

16oz of drip is listed as 308mg.

While this is technically true, it's quite misleading because coffee measurements are typically done by weight. Caffeine content between roast levels only differ meaningfully when measuring by volume instead of weight. Coffee beans swell as they are roasted meaning darker roasts are less dense.

FWIW it does impact coffee at Starbucks, at least in Canada.

A 16oz cup of Dark, Medium and Blonde is listed as 260mg, 310mg, and 360mg respectively.

And if you believe that people routinely drink the same quantities of espresso as they do drip coffee or beer and whiskey that comparison would make sense. But people usually drink much less whiskey and espresso, therefore it's much more relevant to compare commonly used quantities.

Only if you think people drink beer and whisky in "equal quantities".

In the real world, people drink more beer, and far larger cups and amounts of drip coffee than espresso.

what would the quantities of ethanol be in 100ml of whisky vs 100ml of beer?

If you drank the same amount of espresso as you normally would drip coffee, you would die.

Nah, the LD50 of Caffeine is pretty high - something like 14g [0]. Thats way over 100 shots of espresso.

Why would that matter? Only the quantity in serving size matters...

  40% × 0.1 L = 40 mL.
   5% × 0.1 L =  5 mL.
