400,000°, good one.

<p>Is there an ideal amount of time, or an ideal temperature, at which the hot water should be allowed to cool to avoid burning the espresso during the combination process?</p>

Never heard of a long black. I wonder what the benefits are - or just the differences, I guess - for a long black over an Americano.

The argument for the long black is that americanos tend to put water that is too hot directly on the espresso, burning it. Pouring the espresso into the water that you let rest for x number of seconds, allowing it to cool just a bit, prevents this.

Considering that espresso is likely to be brewed at 198-201F, I think that unless if the water is boiling, it would be difficult to burn it.

When making a long black, how long should hot water cool before adding espresso before combining?

A long black is made by pouring espresso into hot water-- effectively the reverse of an americano.

Is there an ideal amount of time, or an ideal temperature, at which the hot water should be allowed to cool to avoid burning the espresso during the combination process?
