Chapter 10: Drinks

We covered coffee in Chapter 2 as the Nine Costs case study. This chapter broadens to the full beverage spectrum — from the radical simplicity of tap water to the baroque absurdity of bottled water, through tea, beer, wine, juice, and soda.

Drinks deserve their own chapter because they're easy to overlook. A beverage feels like a footnote to a meal, not a cost center. But the global beverage industry — excluding water — generates roughly $1.5 trillion in annual revenue [VERIFY], and its environmental footprint is substantial: water use, energy for refrigeration, packaging (the beverage industry is the world's largest user of single-use packaging), sugar sourcing, and the marketing machinery that makes drinking sugar water feel like living your best life.

Coffee (Brief Recap)

Chapter 2 traced coffee through all nine costs. The summary: shade-grown, fair or direct trade coffee from a cooperative, brewed at home, grounds composted, is a low-cost beverage. Industrial sun-grown coffee from deforested land, purchased in a single-use cup with a plastic lid, grounds to landfill, is a high-cost beverage. The same molecule. Different universe.

One addition: coffee pods. Keurig's K-Cups have sold roughly 60 billion units since 2004 [VERIFY]. Most are #7 plastic (mixed material, non-recyclable in most programs). Even the "recyclable" versions require consumers to peel off the foil lid, dump the grounds, and clean the cup before recycling — which almost nobody does. Nespresso's aluminum pods fare better (aluminum is infinitely recyclable and the company runs a return program), but return rates are estimated at only 30 percent [VERIFY].

The single-serve pod is a microcosm of the convenience-vs-waste trade-off: marginally easier, substantially more wasteful.

Tea: The Quiet Beverage

Tea is the most consumed beverage in the world after water, drunk by roughly 2 billion people daily [VERIFY]. Its environmental footprint is modest — tea plants are perennial evergreen shrubs that grow in tropical and subtropical climates, require no replanting each year, and have relatively low input requirements compared to annual crops.

The carbon footprint of a cup of tea is roughly one-third that of coffee [VERIFY]. Water footprint: roughly 30 liters per cup versus coffee's 140 [VERIFY]. Tea doesn't require roasting (a significant energy input for coffee). It's the environmentally quieter option.

The cost is measured primarily in labor.

Tea plantations in India (Assam, Darjeeling), Sri Lanka, and Kenya employ millions of workers — predominantly women — in conditions that have been documented as exploitative. Assam tea workers earn roughly $2 to $3 per day [VERIFY]. Housing provided by estates is often substandard. Healthcare is inadequate. The plantation system in some regions retains structural features of colonial labor arrangements.

The Darjeeling tea brand — marketed as premium, sold at $20 to $50 per hundred grams in Western shops — rests on some of the lowest-paid agricultural labor in India. A worker picking Darjeeling tea earns roughly $2 a day so that the tea can retail for $8 a cup at a luxury tea house [VERIFY].

Fair trade and organic tea certifications exist and capture growing market share, but the majority of global tea production remains conventional with unaddressed labor issues.

Tea bags add a packaging dimension. Traditional paper tea bags are compostable. Many modern "silky" or "pyramid" tea bags are made from PLA (polylactic acid) or nylon — technically biodegradable under industrial composting conditions, but effectively plastic in most disposal contexts. Some release billions of microplastic particles per cup when steeped in hot water [VERIFY]. Loose-leaf tea avoids this entirely.

Bottled Water: The Clearest Absurdity

In countries with safe municipal water — which includes most of Europe, North America, Japan, Australia, and other developed nations — bottled water is perhaps the most indefensible consumer product in the food system.

The numbers:

• Roughly one million plastic bottles are purchased globally every minute [VERIFY]
• Only about 9 percent of all plastic ever produced has been recycled [VERIFY]
• Bottled water costs 300 to 2,000 times more per liter than tap water [VERIFY]
• Nestlé Waters (now BlueTriton Brands), Coca-Cola (Dasani), and PepsiCo (Aquafina) are the dominant US players — Dasani and Aquafina are filtered municipal tap water, packaged and sold at enormous markup [VERIFY]
• The energy required to produce, fill, transport, and refrigerate a bottle of water is roughly 2,000 times the energy cost of an equivalent volume of tap water [VERIFY]

The environmental case is closed. In any country with safe tap water, bottled water is indefensible on environmental grounds. The health case is also closed: US municipal water is regulated under the Safe Drinking Water Act (EPA oversight, regular testing, public reporting); bottled water is regulated by the FDA under less stringent standards with no public reporting requirement [VERIFY].

But — and this matters — not everyone has safe tap water.

Flint, Michigan's lead contamination crisis, which began in 2014, exposed that roughly 6 to 10 million US homes still receive water through lead service lines [VERIFY]. Rural communities, tribal lands, and low-income neighborhoods disproportionately lack safe drinking water. Globally, roughly 2 billion people lack access to safely managed drinking water [VERIFY].

For these communities, bottled water is not a luxury or an environmental failure — it's a necessity. The environmental critique of bottled water is valid as a systemic critique (why isn't everyone's tap water safe?) but cruel as an individual critique directed at people whose tap water is poisoned.

Beer, Wine, and Spirits

Alcohol adds another layer to the environmental calculation: the energy-intensive processes of fermentation and distillation.

Beer has a water footprint of roughly 300 liters per liter [VERIFY] — mostly for growing barley and hops. The carbon footprint is moderate: about 0.5 to 1.5 kg CO₂eq per liter [VERIFY], depending on production scale and packaging. Craft beer from a local brewery has lower transport emissions but higher production emissions per liter (small-batch inefficiency). Industrial lager (Budweiser, Heineken) is more efficient per liter but less interesting per sip.

Packaging matters enormously for beer. Draft beer (kegs) has the lowest packaging footprint. Aluminum cans are next (light, high recycling rate). Glass bottles are heaviest (high transport emissions) but aesthetically preferred by craft consumers. The environmental ranking — keg > can > bottle — is the opposite of the perceived quality ranking.

Wine has a moderate environmental footprint, complicated by the extraordinary diversity of production methods. An organic, biodynamic vineyard in Burgundy and an irrigated conventional vineyard in California's Central Valley are both making "wine." The carbon footprint ranges from roughly 1 to 3 kg CO₂eq per bottle [VERIFY].

Vineyard monoculture is a biodiversity concern — particularly in regions where vineyards have replaced diverse landscapes. Pesticide use in conventional viticulture is significant; grapes are one of the most heavily sprayed crops. But wine also represents multigenerational land stewardship, cultural heritage, and terroir — a deep connection between product and place that industrial agriculture has severed for most foods.

The heaviest environmental cost of wine may be the glass bottle. Wine bottles weigh 400 to 900 grams, and the wine itself weighs about 750 grams — meaning you're shipping nearly as much glass as wine. Alternative packaging (bag-in-box, aluminum cans, lighter bottles) dramatically reduces the transport footprint but faces consumer resistance from wine drinkers who associate quality with heavy glass.

Spirits are the most concentrated alcohol: distillation requires significant energy (heating liquid to 78°C and collecting vapor), but the final product is consumed in small volumes. The per-serving footprint of spirits is moderate — roughly comparable to wine. The mixer (tonic water, soda) often has a larger footprint than the spirit itself.

Juice: The Fruit Fraud

A glass of orange juice requires three to four oranges, strips the fiber (which slows sugar absorption), concentrates the sugar (a glass of OJ has roughly the same sugar content as a glass of Coca-Cola [VERIFY]), adds pasteurization energy, requires packaging (carton, plastic, or glass), and ships heavy liquid across oceans.

Nutritionally, juice is a downgrade from the fruit it came from. Environmentally, it multiplies the fruit's footprint by the number of fruits per glass plus processing and packaging. Financially, it costs more than the fruit.

The orange juice supply chain is particularly revealing. Brazil produces roughly 70 percent of globally traded orange juice concentrate [VERIFY]. The industry is controlled by three companies — Cutrale, Citrosuco, and Louis Dreyfus — that together control an estimated 80 percent of the world's orange juice concentrate market [VERIFY]. Concentrate is frozen, shipped in bulk tankers, reconstituted at destination, packaged, and sold as "100% juice."

"Not from concentrate" (NFC) juice skips the concentration step but adds a different one: the juice is deoxygenated and stored in aseptic tanks for up to a year [VERIFY], then flavor packs — proprietary blends of orange oils and essences — are added to restore the taste that processing stripped out. "Fresh-squeezed" it is not.

Apple juice tells a similar story. A significant portion of US apple juice comes from Chinese concentrate — China produces roughly 40 percent of the world's apple juice concentrate [VERIFY]. The apples are pressed in China, concentrated to reduce shipping volume, shipped across the Pacific, reconstituted in the US, and sold with labels featuring pastoral American orchards.

The direction: eat the fruit. Skip the juice. If you want juice, squeeze it yourself.

Soda: Sugar Water and Plastic

Coca-Cola was named the world's largest plastic polluter for the fifth consecutive year in the 2023 Break Free From Plastic brand audit [VERIFY]. The company produces roughly 3 million tons of plastic packaging per year [VERIFY].

Soda is, at its core, one of the simplest products in the food system: water, sugar (or high-fructose corn syrup), flavorings, carbon dioxide. The raw ingredients are cheap — the cost of the liquid in a bottle of Coca-Cola is estimated at roughly $0.02 to $0.03 [VERIFY]. The cost you pay is for the brand, the packaging, the refrigeration, and the marketing.

The health cost is well-documented — sugar-sweetened beverages are a primary driver of obesity, type 2 diabetes, and dental disease globally. The environmental cost is primarily packaging: single-use plastic bottles, aluminum cans, and the refrigeration energy required to keep them cold.

Diet soda removes the sugar but retains the packaging problem and adds questions about artificial sweetener impacts on gut microbiome and metabolic processes (research is ongoing and inconclusive [VERIFY]).

The behavioral insight: soda consumption has declined in the US (roughly 25 percent since peak consumption in the late 1990s [VERIFY]) but is rising rapidly in lower-income countries, particularly in Africa and Southeast Asia, where Coca-Cola and PepsiCo are aggressively expanding. The health and environmental costs are being exported.

Tap Water: The Radical Act

After tracing the costs of every other beverage, the simplicity of tap water is startling.

Carbon footprint: negligible. Water footprint: the water itself, treated and delivered. Land use: none. Biodiversity impact: minimal. Packaging: a glass you already own. Health: safe (in properly managed municipal systems), with added fluoride for dental health in many jurisdictions. End of life: goes down the drain, back into the water cycle. Psychic cost: zero — no labels to read, no certifications to evaluate, no ethical dilemma to navigate.

Municipal water systems are one of civilization's great achievements — massive public infrastructure that delivers safe drinking water to billions of people at a cost of roughly $0.002 per liter [VERIFY]. The privatization of water (and the marketing of bottled water as superior to what comes from your tap) is one of the great confidence tricks of the modern economy.

The radical act is not buying a $6 cold-pressed juice or a $4 kombucha. The radical act is drinking from the tap.

The beverage chapter is, in some ways, the simplest in the book. The gap between the best and worst options is wider than in any other food category. The single largest impact reduction available to most people is eliminating bottled water in favor of tap water. The second is eliminating or reducing soda. These are not ambiguous recommendations.

What makes it harder: convenience, habit, marketing, and in some cases genuine necessity. The parent who sends a juice box because the school won't let kids bring open containers. The construction worker buying a cold Gatorade at a gas station. The family in a rural community where the well water tastes like sulfur. Context, always context.

But for the median consumer in a wealthy country with safe tap water: drink from the tap. Brew your coffee at home, compost the grounds. Choose draft over bottles. Eat the fruit instead of juicing it.

Not perfection. Direction.
