Space Joe

Pettit If the inability to enjoy a hot cup of coffee in space has kept you from pursuing your cosmonaut dreams, last week's invention of the zero-G coffee cup by NASA astronaut Dave Pettit is sure to make you tingle.

Pettit is known for funky space inventions, but when he arrived at the International Space Station, he had one goal in mind: Find a way to enjoy his beloved joe from a cup, rather than a bag & straw. Liquids in space can be a messy proposition, and hot coffee introduces an element of risk as well, but that wasn't going to stop Pettit from devising a method of enjoying his java from a cup.

Using a piece of his mission book, he formed a vessel with a tear-drop shape that is closed at one end. The surface tension within the cup keeps the coffee inside instead of floating about the station. He suggested that his invention could apply to more than just coffee -- future space colonists could utilize this kind of cup for celebratory toasts.

So now that the coffee cup question has been answered and you're back on track to becoming an astronaut, you'd better hit the books -- time to learn Russian.

Health Watch: Caffeine & Alertness

Coffee_cup_drawing You drink it to wake up, to focus more, to get you through the day -- heck, even to sober up. But has the effect of caffeine on your central nervous system been overstated? A group of researchers from the National University of Ireland in Galway think so. In fact, they think that the only benefit you see from your caffeine consumption is to further your caffeine consumption.

Through their study, they were unable to find a measurable difference in alertness and cognitive ability in participants, and found that the only difference was the abatement of caffeine withdrawal symptoms regular caffeine consumers felt in the morning after their body had metabolized caffeine overnight.

For at least a month, they gave a participants either a placebo or a caffeine pill equal to one cup of coffee to take three times a day. They then tested their ability to concentrate, resulting in no discernible difference between the control group and the caffeine consumers. They also tested the control group's reaction to caffeine after having not had the drug in their system for quite some time and were also unable to track a noticeable difference in their level of concentration between their placebo state and caffeinated state.

So if it's not really waking us up, helping us focus and getting us through our day....why are we drinking it? Well, despite the position that drinking it may essentially be a self-fulfilling prophecy, we'll keep drinking it for taste! Yeah, that's right -- for taste.

Recipe: Espresso Biscuits -- Eggless

Here's a great recipe for anyone who has an egg allergy -- or if you're in the mood for cookies but don't have any eggs on hand!

Espresso_cookie Ingredients

  • 1 1/2 cups all purpose flour
  • 1/2 cup Dutch process cocoa powder
  • 1 tablespoon finely ground espresso beans
  • 1/2 lb unsalted butter,at room temperature
  • 3/4 cup confectioners sugar
  • 1 teaspoon vanilla extract

Directions

  1. Preheat oven to 350*F with two racks spaced evenly apart. Line two baking sheets with parchment paper. Sift together the flour,cocoa, and ground espresso; set aside.
  2. In a bowl of an electric mixer fitted with the paddle attachment,combine the butter, confectioners sugar and vanilla; beat on medium speed until creamy,3-4 minutes. Reduce speed to lw, and gradually beat the flour mixture into the butter mixture, scraping down the sides of the bowl twice.
  3. Roll a heaping tablespoon of dough between the palms of your hands to form a ball. Place on prepared baking sheet; repeat with remaining dough, spacing cookies 2 inches apart. Place the tines of a fork into dough and gently flatten the ball into biscuit shape. Bake biscuits until just firm to the tough, 12 to 15 minutes, rotating half way through. Transfer to a wire rack to cool.

These are great to serve along with coffee or espresso when you're entertaining.

Health Watch: Caffeine & Training

Cyclist Are you a cyclist looking for a quicker way to regain your energy stores after a long distance ride? Well, this interesting study published in the Journal of Applied Physiology indicates that caffeine has a significant positive impact on helping you to rehab more quickly after a long ride. The catch? You have to drink a lot of it -- which may not be a negative thing for us caffeine maniacs.

At the School of Exercise and Sport Science in the University of Sydney, researchers found that study participants that drank caffeine-supplemented high-carb drinks after long rides restored much more of their glycogen stores (which gives the primary energy for endurance activities) when compared with participants who drank just a regular high-carb drink.

Recipe: Chocolate Espresso Pots du Creme

Whilst poking around for a good Thanksgiving treat, we found a delicious recipe for Chocolate Espresso Pots du Creme at Harvest Eating. You can check out their video on how to make the recipe here.

Pots_du_creme Ingredients

  • 8 ounces Bittersweet chocolate
  • 6 Egg yolks

Living in a Caffeine Free World

D_caf_strips If you read our post on Monday about the caffeine levels of different types of brew, you'll recall that decaf coffee is not completely caffeine-free -- it does have a slight content level, but considerably less than other types of coffee. If you're sensitive to caffeine and are strictly a decaf drinker, you might be interested in these caffeine test strips.

According to the manufacturer's website, up to 30% of the coffee you drink out in the world is not actually decaf, and their handy new strips will help you tell the difference well before you feel the heart pumping! We haven't tried them yet -- but if you do, please let us know what you think!

Caffeination Time -- Come On! (It's Time for Caffeination)

Caffeine_2d OK, so it might not necessarily be as age-old as the chicken vs. the egg debate (wait, didn't they solve that?), but the argument over which has more caffeine -- drip coffee or a shot of espresso -- is often kicked around the ol' coffee shop. Obviously, like any good debate, the answer varies almost as widely as the number of preparations for caffeine-carrying plants around the world.

The first thing to keep in mind in this discussion is the plant: Are we talking Robusta or Arabica? Arabica has less caffeine than Robusta, so the bean blend is important to know before you guesstimate your caffeine intake. Secondly, what's the roast look like? A super dark roast eliminates a large portion of the caffeine content, sending those molecules up in smoke. Lastly, take a look at how much you're consuming, because quantity matters: If you're drinking 4 oz. of espresso vs. 7 oz. cup of drip, your intake will be a lot different  than these standards:

  • Percolated (7 oz): 140mg
  • Drip (7 oz): 115 - 175mg
  • Espresso (1.5 - 2 oz): 100mg
  • Brewed (7 oz): 80 - 135mg
  • Instant (7 oz): 65 - 100mg
  • Decaf, brewed (6 oz): 5mg
  • Decaf, instant (6 oz): 3mg

In general, the longer the coffee grounds are in contact with water, the more caffeine will be extracted into your brew. Caffeine is largely responsible for coffee's bitter taste, which was one of the motivations behind the development of espresso: The relatively short brew time results in a significantly less concentration of caffeine, allowing you to taste other flavors in the coffee.

Meet the Real Juan Valdez

Photo of Paul Rice from SF Chronicle On a visit to the coffee-growing hills above San Lucas, Rice cultivated what would later become the American fair trade movement. Founded in 1998 in a converted warehouse in downtown Oakland, TransFair USA began as a bare-bones operation with an unusual premise - put more money in the pockets of farmers in the developing world by persuading consumers thousands of miles away to pay a premium in the name of social justice. Modeled after organic produce and dolphin-safe tuna, Rice started the organization with the stark black and white label that told shoppers their coffee came from farmers who received a "fair price."

The San Francisco Chronicle just wrote this very interesting profile of the man who founded the Fair Trade movement for coffee, Paul Rice. We highly recommend the read!

Rain in India Could Storm Your Wallet

Plant "...all for the price of a cup of coffee." The Christian Children's Fund might have to change their pitch-line in the coming months, as India reports their Robusta coffee crops are down due to the excessive rain they've been experiencing -- a drop which may result in an increase in coffee prices around the world.

India's highest producing region, Karnataka, experienced intense rains during coffee's blossom season, which will likely impact the amount of beans they are able to harvest. While this news story focuses on the fact that Robusta is primarily used in instant coffees, it is also very often used in high-end gourmet brands (such as Lavazza or Illy) in their espresso blends to create a thicker crema and a bolder body. Robusta is bitter due to it's higher caffeine content, so it's not used in high quantities, but the increase in prices could have an impact on the cost of your favorite coffee beans -- whether or not you'll see this passed on to you remains to be seen.

However, coffee's global commodities pricing has dropped significantly over the past several months, due to the economic issues seen in Europe and the US, so perhaps these environmental and economic issues will balance each other out.
