Spotting abnormal tire wear and correcting the cause can significantly extend tire life. Normally, tires will wear evenly across their surface until they reach the wear bars, which are 2/32nds of an inch above the bottom of the tread. When the tires are worn to the wear bars, they should be replaced.
One shot (1.5 ounces) of espresso has about two tablespoons of coffee (about 1/4 ounces). For best flavor, one shot of espresso, or two tablespoons of coffee, should be used to make 6 ounce of coffee drink. Likewise, a 12 ounce coffee drink will taste best with two shots of espresso.
The difference between these shots are the extraction time, and thus the amount of water passed through the coffee grains. A regular shot of espresso is pulled for 22-26 seconds, and results in a standard shot â what most people are used to. A ristretto is pulled for closer to 15 seconds, and thus has little more than half the water of a regular shot and is much more concentrated. This leads to a stronger-tasting, more acidic drink. A long espresso, then, is the opposite, pulled for over 40 seconds, resulting in more dilution and a less concentrated shot.
