But let’s be honest… running a successful and (ideally) profitable coffee house is something of a high-wire act at the best of times. And — economically-speaking — these aren’t the best of times. You’ve got a budget to watch; a creeping expense column can throw things out of kilter. Fast. It’s not going to do you or your environmentally-minded customers any good for you to bankrupt yourself in the name of ecology.

That said, there are savings to be found in running a more efficient and sustainable coffee house, coffee shop or espresso bar. Some of these savings can be realized pretty quickly, others require a longer view. If you can, don’t just consider today’s bottom line, but tomorrow’s. And next year’s. And — for goodness sake — don’t lose sight of the ultimate bottom line here… the planet’s climate is in crisis. And it shouldn’t surprise you to learn that the viability of specialty coffee is at the forefront of that crisis.

In greening up your coffee house, there are (at least) three distinct areas where you can bring your efforts to bear: reducing energy, increasing sustainability, and making it easier for your customers to go green, too. We’ll look at each in turn. There’s a lot to slog through here, so I’ll get right to it.

Reduce energy.

A coffee shop is an energy sink. You’ve got lots of things to keep hot, things to keep cool, and excruciatingly specialized equipment to get them all mixed together. Where do you begin?

Start with an energy audit. Chances are your power company will audit your business at no charge, and provide you with a fairly comprehensive list of recommendations. It’s a great place to start… and an ideal way to benchmark where your business stands, right now. You’ll want that baseline to measure against after you’ve made some improvements.

While your power company will have lots of tips for you in terms of properly insulating your space (ceilings, walls, windows, doors) and savings you might achieve in terms of lighting (switching to CFL fixtures) and the like, chances are they won’t know enough about your specialized equipment — say, espresso machines — to tell you the whole story. You can augment what you learn on an audit report by using a portable or panel-installed power use monitor (think Kill-A-Watt and the like) to measure how much energy your specialized equipment consumes.

You’ll find your coffee house has any number of power-sucking commercial appliances. You’ll probably learn which of these costs you the most to operate in the course of your energy audit; you may not learn, however, which are the most efficient… or more importantly, which aren’t. Lacking any information to the contrary, here’s where you might want to start.

• Dishwashers. You probably know you can save energy and water by running your dishwasher only with a full load. (Of course you do!) You may not know that if you invest in an Energy Star rated commercial dishwasher you can see a pretty immediate return on your investment. An efficient dishwasher can save your coffee house up to 90 MBtus, (about $850 a year on your energy bill) and 52,000 gallons of water (probably another $200 a year).¹
• Refrigerators and freezers. Today’s Energy Star rated chill chests are as much as 35% more efficient² than the bog standard item of the last 10 years, due to advances in compressor and fan-motor efficiency and new anti-sweat technologies (’cause nobody likes a sweaty fridge.) Your new refrigerator can pay for itself in a little more than a year.
• Espresso machines and brewers. In a great many cases, you can insulate the boilers of your always-on equipment (much like you’ve insulated your shop’s hot water heater, right? Right?) Mind you, if you don’t know the internals of your brewers like the back of your hand, it’s probably best to have it done by your service-tech. A flaming espresso machine is decidedly not eco-friendly; we’re probably talking about kevlar, not simple fiberglass batting.
• Coffee roasters. Clean, clean, clean! A clean roaster is not only a safe roaster, it’s also far more efficient than one that’s choked up with years of coffee oils, a creosote-filled exhaust and clogged air vents. You may be surprised with the energy savings you realize.

So maybe it’s not in your budget to spring for new, high-efficiency appliances this year… there’s no reason you can’t make sure the appliances you have are operating at peak performance. Clean your fridge’s evaporators, condensers, and heat-exchange coils. Replace worn and leaky door seals. Better still, get a regular service regimen going so that all of your equipment is operating well throughout the year.

Increase sustainability.

Greening up entails more than just curbing your shop’s power demands. It’s also about breaking some bad habits, many of them having to do with things we simply throw away. After decades of disposable everything, we’ve become conspicuous consumers of our limited natural resources. And it’s got to stop.

• Enough with the plastic cold cups already. Bio-polymer alternatives biodegrade in commercial composting landfills inside a month; plastics are forever. Greenware cups from Fabri-Kal make petroleum-based plastic cold cups obsolete.
• Nix those unrecyclable paper hot cups. Look into compostable paper cups like the ecotainer from International Paper, lined with a corn-polymer resin that’s compostable and will degrade over time.
• Still double-cupping? Just stop, already. Please. Products like the Java Jacket are pretty much de rigeur and new biodegradable entrants like the ecoSleeve appear to work just as well for cold cups, too.
• Want to take a really big step? Consider getting rid of disposables altogether!
• Recycle! How many gallons of milk does your coffee house consumer every day, and how many plastic jugs do you empty as a result? If you’re not recycling, that adds up to a heaping pile of forever in a landfill. Recycle your consumables. More, make it easy — like, really easy — for your customers to do the same.
• Use green cleaning products. Green cleaning agents are safer for your employees to use, and they typically don’t contain any VOCs (volatile organic compounds).³ Check with the Green Restaurant Association for a list of endorsed products.
• Buy food locally. When you purchase locally grown foodstuffs, suddenly all of your customers are localvores. More to the point, locally produced milk, fruits and vegetables are fresher, taste better, and your dollars support your own community (rather than some faceless transnational food cartel.)

Make it easier for your customers to go green, too.

People are waking up — finally! — to the stark realities of global climate change. And increasingly, folks the world over want to do something about it. People are setting back their thermostats, choosing cars with better gas mileage, replacing their light bulbs — all the while looking for opportunities to do more. You can help.

• Offer organics. By all means, start by offering a selection of great organic coffees. More, make an organic coffee your house blend; your standard espresso. But don’t stop there! Look for local, organic milk and dairy suppliers, bakers and folks who farm great produce. Make organic an every day thing.
• Switch to recycled paper products. From paper towels to napkins to bath tissue, recycled paper products — no longer limited to options of “brown” and “rough” — are an increasingly compelling alternative to virgin fiber sources.
• You know and I know that folks just love those cute little bottles of water. More, we both know those little plastic bottles are just plain stupid, ecologically. So do something about it. Offer ice-cold, filtered water to refill your customer’s reusable bottles, to start.
• Encourage customers to use their own mugs. Whether you want to host a wall of customer cups for your regulars, or offer a discount for folks who drop in with their travel tumbler in-hand, get behind your customers’ efforts to green up their own lives.
• Educate your customers. Going green isn’t one of those private, hair-shirt-wearing sort of things… it’s something that you want to make some noise about. Let your customers know that you’re going green. And how. And why. By demonstrating your commitment to the environment, and by making it easy for your customers to make good choices in your place of business, you help them make greener, more sustainable choices everywhere.

Final thoughts… and an invitation.

Greening up your coffee house can save you money (in the long run, certainly, even if it may have some up-front costs). And going green can improve the morale of your staff even as it boosts the loyalty of your customers — all of them. Greening up means a safer, healthier place of business, and will ultimately lead to a safer, healthier environment. Most of all, going green is simply the right thing to do.

While I’ve thrown a lot of ideas into this article, it’s really just a start. I welcome your feedback, your ideas, and your stories about how you’re greening up your coffee house… the challenges you face, and how you overcame them. We’re in this together, after all.

I’m not the only one talking about the intersection of coffee houses and sustainability these days. See also:

“Caffeine appears to block several of the disruptive effects of cholesterol that make the blood-brain barrier leaky,” said Dr Jonathan Geiger, who led the study.

“High levels of cholesterol are a risk factor for Alzheimer’s disease, perhaps by compromising the protective nature of the blood brain barrier.

“Caffeine is a safe and readily available drug and its ability to stabilise the blood brain barrier means it could have an important part to play in therapies against neurological disorders.”

And while we’re at it:

• Caffeine may help protect memory in women
• Coffee is tied to a lower risk of Parkinson’s
• Coffee is linked to a lower risk of Diabetes
• Coffee drinking is related to a lower risk of Liver Cancer.

Drink up!

“Of course, we intended for Cocaine energy drink to be a legal alternative the same way that celibacy is an alternative to premarital sex,” Ivey said. “It’s not the same thing and no one thinks it is. Our product doesn’t have any cocaine in it. No one thinks that it does. We think it is most likely legal in the United States to ship our product.”

Presumably the company’s planned launch of “Crystal Meth” pop-rock candy and “Exstacy” jelly beans are unaffected by this setback.

Sheesh.

• Enough of the paper filters, already. If you enjoy your coffee in a press pot, good on you, you’re already there. But if you’re making a drip cup, consider some alternatives to your paper coffee filters. The gold standard of reusable drip filters are made by SwissGold, and they have a product line that covers most every filter basket style — from Mr. Coffee to Bunn to Melitta-styled cone filters — used in auto-drip machines today.
• Enough of the bottled water, too. I’ve written quite a lot about the importance of good water for good coffee. So by all means, use great water, but make it great yourself. Start with water from your own tap and filter it with any number of great filtration products (I like Brita, and PUR.) You’ll save oodles of money, and save oodles of carbon emissions from all the shipping that bottled water requires.
• Heat your water on-demand. Long-time readers will know that I’ve proclaimed my love for Bunn coffee makers in the past… but I have to tell you, that relationship is over. Home coffee makers that keep water hot 24 hours are energy hogs, pure and simple. Instead, use a water kettle to boil up only exactly as much water as you need. Chances are it’ll take no more time than your Bunn ever did.
• Take your mug on the road. If you’re heading to your local coffee house, take your mug with you! There’s thermal travel mugs and tumblers of every sort to make sure you don’t spill a drop on your commute, and chances are your coffee shop will thank you! (One of a coffee shop’s biggest costs is paper, and the lion’s share of that is paper cups.)
• Choose Fair Trade Certified™ and Organic coffee. Yes, you really can make a difference by choosing coffee with eco-friendly bona fides. And you have been! Sales of Fair Trade coffee rose ten-fold between 2000 and 2005, and Fair Trade and Organic coffee sales are right now seeing accelerating double-digit growth. Keep it up! These coffees are ecologically sound, sustainable, and make for safer, healthier coffee-growing communities.

Two years on and now The New York Times is taking up the cause — and on the reasonable side of the matter. Good on them.

Several good studies have linked regular coffee consumption to a reduced risk of developing Type 2 diabetes, colorectal cancer and, in men and in women who have not taken postmenopausal hormones, Parkinson’s disease.

Most studies have not linked a high intake of either coffee or caffeine to heart disease, even though caffeinated coffee raises blood pressure somewhat and boiled unfiltered coffee (French-pressed and espresso) raises harmful LDL and total cholesterol levels.

Caffeine itself is not thought to be a problem for health or water balance in the body, up to 400 milligrams a day (the amount in about 30 ounces of brewed coffee). But pregnant women should limit their intake because more than 300 milligrams a day might increase the risk of miscarriage and low birth weight, the panel said.

Mice prone to an Alzheimer’s-like disease were protected by drinking water spiked with caffeine equivalent to what people get from five cups of coffee a day. And a study of more than 600 men suggested that drinking three cups of coffee a day protects against age-related memory and thinking deficits.

Now that they’ve cleared that up, I understand there’s a little dust-up over at the Justice Department they might want to have a look at…

Still today there remain those with an axe to grind with coffee — more frequently with its chief agent provocateur, caffeine — and who take no small delight in sewing seeds of fear, uncertainty and doubt where the health aspects of coffee are concerned. These reports typically offer no sources at all, or perhaps small-scale studies that have been dated for 40 years.

Let’s see if we can’t shed some light on the subject… using multiple, credible and authoritative sources, and send coffee’s naysayers scuttling back under their rocks.

Coffee and Health

Like so many of the beverages we enjoy today, coffee was once prescribed as a tonic for what ails you… and provided that what ails you is a lack of alertness or a sour mood, it’s good on its promise. Let’s leave patent medicines and snake-oil salesmen aside for the moment, though, and ask: is coffee good for you?

The answer is yes!

Coffee has been a frequent subject of scrutiny by the medical community… perhaps because it’s so widely consumed, yet offers no apparent nutritive value. Or, maybe doctors are just looking for a really good cup of coffee.

Despite some 40-50 years of study, the medical field has yet to draw a direct correlation between moderate consumption of coffee and any medical disease or chronic health condition. Studies that have suggested worrisome links between coffee consumption and reproductive health, for example, have been put to rest by subsequent studies — larger, and more thorough — that have exonerated our favorite beverage.

More recent studies by the medical science community are now finding numerous positive benefits of moderate coffee consumption. These studies suggest that drinking coffee may reduce risks of colon cancer and liver cancer; cirrhosis of the liver; may reduce the risk of Parkinson’s Disease and the onset of diabetes. More, brewed coffee has been found to have 3 to 4 times the amount of cancer-fighting anti-oxidants as green tea. Further, coffee can prevent or reduce the likelihood of developing gallstones, even prevent cavities.

Coffee and Caffeine

Coffee contains caffeine, a mild stimulant to the central nervous system. The caffeine in coffee occurs naturally; it’s not added (it is, however, added to many soft drinks.) Coffee — with its stimulating constituent, caffeine — is the worlds most popular mood-altering substance on the planet, and has been for more than 300 years.

Caffeine promotes wakefulness by interfering with adenosine, a chemical in the body that acts as something of an natural sleep-promoting drug. In addition to its wakeful properties, caffeine — in moderate amounts — has been shown to enhance mood and increase alertness.

Caffeine has been shown to decrease muscle pain and augment the pain-relieving capability of other drugs, alleviate asthma symptoms and boost athletic endurance and performance as well as heightening alertness and lifting mood. Heck, it even helps combat jetlag! The key, of course, is the phrase we seem to hear a lot… moderation.

What’s moderate? Most doctors will agree that 3 to 4 cups of coffee a day can be considered moderate consumption. What’s moderate for you, however, is largely a matter of how you respond to caffeine. If you have questions or concerns about your own consumption of caffeine, talk to your doctor.

Coffee and Nutrition

Nutritionally speaking, brewed coffee is pretty much inert. It has virtually no calories or fats, no carbohydrates, no sodium, no cholesterol… if it were required to carry a nutritional product label, that label would consist mostly of a lot of zeros. (In fact, coffee is exempt from federal food label programs precisely because it has zero nutritive value.)

That said, coffee does offer a number of trace minerals (Thiamin, Niacin, Folate, Phosphorus, Magnesium, Manganese) and is a good source of Potassium, Pantothenic Acid and Riboflavin. A 6-ounce cup of brewed coffee may contain 2 to 4 mg of Sodium… mostly from the water used to brew the coffee and not the coffee, itself.

What about the stuff we add to coffee?

While coffee itself has virtually no nutritional impact, the things we add to our coffee will, in turn, dial up those numbers. And, if what we’re really doing is adding a little bit of coffee to a large cup of steamed milk (with a few tablespoons of flavored syrups on top!) the results can be pretty dramatic. Dieters beware the trendy cup!

So is coffee the new health food? Perhaps. What’s increasingly clear, as we continue to learn about coffee and its complex constituent components and compounds, we find far more benefits than risks. For most people — in moderation — coffee is good for you. Abundantly so.
