Coffee And Health

In the early days of the coffee craze, before the first Starbucks arrived in my town, I owned a tea and coffee house for several years. At the time, espresso was something new for most people, and a lot of my customers had questions. I decided to teach a class on coffee at the shop, and learned in the process that there are several misunderstandings about buying, storing, and grinding coffee that when corrected can lead to a much more enjoyable cup of coffee.

True coffee connoisseurs know that buying coffee beans in small amounts that allow you to brew your coffee within a day or two of being roasted will result in the closest to a perfect cup of java. If you keep the beans in an air-tight container the flavor will remain strong for seven to ten days. Contrary to popular belief, storing beans in your refrigerator or freezer will actually diminish the flavor. There are two reasons for this. First, the beans will soak up the flavors of other stored items. Secondly, moisture affects the oils in the roast. Better to store that container on the counter (in a dark, cool place, if possible). If you can't smell an aroma or it's unpleasant, the beans are past their prime.

Soapy water can leave a residue, so when cleaning your coffee storage, use a dry cloth or paper towel to soak up the oil. Clean the container regularly because oil can get rancid over time. Also, frequently clean the equipment you use for brewing. Again, don't use soap because of the residue. Instead use vinegar and salt and rinse thoroughly.

Always grind only the amount you will use immediately. Once exposed, the oils in the beans disperse, affecting the coffee flavor. If you grind your beans the night before you brew your morning cup, you will be losing flavor. Switch to grinding in the morning, unless you don't want to wake your sweetheart with the noise from the grinder. How fine or coarse the grind should be depends on how long the hot water will be in contact with the coffee grinds. The shorter the length of time, the finer the grind so that the surface area is maximized. Here are the consistencies you will want for the different methods of brewing:

Drip Brew: Grind to a character similar to table sugar if the drip cycles range from four to six minutes. Grind to a finer consistency if less.

French Press: Use an extremely coarse grind.

Espresso: Very fine, powder-like. The extraction time of espresso should be between 25 and 30 seconds. If a one ounce extraction takes longer, use a coarser grind; if it takes less time, grind finer.

How much coffee do you grind? For brewed (and French Press) coffee, three tablespoons for eight ounces of water. For espresso, an ounce (7 grams) for a single shot. Double that for a double shot.

Time and again I heard from my customers that they had no idea what a good cup of coffee really tasted like until after they had followed these easy guidelines. Try it. It's the small things that will make your coffee drinking experience sublime.

Here is an article that tells the secret of creating the perfect foam with steamed milk for making a wonderful cappuccino. As you'll see creating the perfect foam isn't as easy as it may seem ...

Most places that serve cappuccinos in the United States have not trained their baristas in the art of properly frothing milk. The foam that they create is usually a dry, tasteless, large celled collection of bubbles that sit on top of the espresso like a meringue.

With a little care, you can create steamed milk that is velvety smooth like the texture of wet shaving cream. The bubbles will be so small that you can barely see them! This is the way it's supposed to be, because this way, it will blend with the espresso, creating a harmony of the flavors instead of a dry, tasteless cap floating on top. Let's Begin.

First off, it's important to start with cold milk that's just out of the fridge. Pour the milk into the steaming pitcher until it is just about 1/3 of the way full. Milk will double to triple in volume after the frothing process. A stainless steel pitcher works best. It will dissipate some of the heat, allowing more time to infuse air into the milk before the milk gets too hot.

For a home made cappuccino, you'll have to learn the art of creating a perfect foam.

Also use a thermometer to get the milk to the correct temperature of 145 degrees. There are many thermometers made for this purpose that will clip onto the side of the pitcher for convenience.

The Technique:

Purge the steam wand onto a damp towel by releasing the valve for a few seconds. Be very careful not to burn yourself, the steam will be extremely hot. This purging will get all of the water out so you don't get it in your milk.

Next, submerge the wand into the milk and quickly turn the steam on full power. Avoid letting the tip of the wand come out of the milk. This will cause splattering and create large, tasteless bubbles.

Adjust the wand so that it is pointing off center in order to get the milk to flowing in a rapid, circular motion. Maintaining this fast, circulating vortex is vital.

Then, slowly lower the pitcher until the tip of the wand is just below the surface of the milk (keeping the circulation going). When you can hear a hissing noise, similar to bacon frying, you have reached the perfect position for the wand to inject air into the milk.

Try to maintain this hissing noise while keeping the milk rotating. You will have to slowly lower the pitcher as the milk volume rises in order to keep the wand tip just under the surface.

By keeping the milk flowing in a rapid circle, any large bubbles that are accidentally created will be rolled into the milk and eliminated. Continue steaming until the milk reaches 145 degrees. Be careful not to get the milk too hot, it will scald giving it a bad taste.

That's pretty much it! If you have a few large bubbles, you can try to get rid of them by tapping the bottom of the pitcher lightly on the counter. Serve immediately and enjoy some of the silkiest frothed milk you have ever tasted!

One more thing, now that you know how to properly steam the milk, notice how few coffee houses have baristas that take care in this process. Very few use thermometers and end up scalding the milk, or leaving it too cold.

Most will just leave the pitcher sitting there while the wand blows into the milk. Some will use an up and down motion, but this does absolutely nothing for creating tiny, velvety bubbles. It's the rolling action of the milk that's needed.

If you find a barista that shows this skill of frothing milk, then stay with him! He's been trained and probably takes pride in what he does.
