How Much Water Does It Take To Produce Oat Milk?

Oat milk is one of my personal favorites. It’s also becoming a popular choice among others, as oat milk is currently in short supply across the country. When frothed, I think it’s the creamiest, and it also has the smallest carbon footprint.

In terms of water, a liter of oat milk necessitates the use of 48 liters. When compared to the water used to make dairy, soy, and almond milks, this is a huge savings! Oat milk also has a minimal carbon footprint, with 0.18 kilos of carbon dioxide emitted per 200 milliliter glass.

The only real disadvantage of oat is its cost, which is roughly $5 per half gallon. Oat is substantially more expensive than other options, and it is also less commonly available than its competitors.

How much water does a gallon of oat milk require?

Making oats takes around 6 times less water than making almonds. The amount of water required to manufacture different varieties of oats varies slightly, however rolled oats are the most prevalent in oat milks. To cultivate 1/2 pound of rolled oats, or roughly 1 cup, it takes around 145 gallons of water. Oat milk, like almond milk, is made using a 1:14 ratio of oats to water, with an extra cup or two added to soak the oats beforehand. From start to finish, oat milk requires approximately 145 liters of water and an additional 4-6 cups of water.

Is oat milk good for the environment?

When compared to cow’s milk, almond milk, and soy milk, oat milk has the lowest overall carbon footprint, according to data published by Columbia University’s Climate School. A seven-ounce glass of carbon dioxide contains around 0.4 pounds.

Isn’t oat milk just water?

What exactly is oat milk? Oat milk is simply combined rolled oats and water, then filtered to remove the pulp. The end product is a creamy, easy-to-make oat milk!

Almond Milk

Almond milk emits less environmental gases and requires less land than dairy milk, but it is notorious for its high water consumption. Almond milk uses the most water of any of the dairy alternatives: a single glass of almond milk requires 130 liters of water.

About 80% of the almonds used in milk in the United States are grown in California, however due to the hot temperature, the almonds’ high water consumption puts a lot of stress on the dry, desert soil, especially during the frequent heatwaves and fires that ravage the state.

What role do bees play in this? All those almond trees need to be pollinated! The burden of the bees increases as the almond industry expands. Every spring, about 70% of commercial bees in the United States are enlisted to pollinate almonds. It’s believed that one-third of the bees died last year as a result of the stresses of this growth mismatch.

If you’re trying to figure out if almond milk or oat milk is better for you, look at the ingredients on the label. Both employ oils and other chemicals to give them a smooth milk-like feel.

Coconut Milk

Coconut sounds like a refreshing drink, and it appears to be something a caveman (or woman) would like. Heartwarming, romantic, and with a lovely tree to call home! However, the story is one of sweatshop conditions in poor countries, where pickers are paid less than a dollar per day.

Farmers are taking shortcuts and even forcing monkeys into inhumane labor techniques to meet worldwide demand for coconuts, according to a PETA report that reveals how the animals are attached to poles and forced to mount trees to shake loose the coconuts (an animal abuse story that has garnered international attention). “The coconut is an awful tragedy,” Isaac Emery, a food sustainability consultant, says. Cooking with coconut oil is a luxury, but it was brought to market under tough circumstances.

Meanwhile, the rainforest is being cleared to make way for these rows and rows of trees, which contribute very little to the planet’s biodiversity. According to a New York Times study, rainforests in Indonesia were clearcut at a rate of three acres per minute between 2007 and 2014 to make room for coconut palm palms. Choose Fair Trade certified coconut products to avoid supporting unsustainable practices.

Rice Milk

Rice milk is noted for being a less expensive option than its nut milk counterparts. However, when compared to other vegan milks, rice provides nothing in the way of nutrition or environmental benefits. Rice absorbs water and emits more greenhouse gases than any other plant species, according to an Oxford research. Furthermore, the swampy paddies leak methane into the environment, as well as allowing germs to flourish and be released into the atmosphere. When it comes to water pollution, rice is one of the worst offenders.

Hazelnut Milk

The chocolate lover’s dream, the innocuous hazelnut, is on the rise. Hazelnuts, like all nuts, grow on trees, and all treesindeed, all plantsuse the energy of sunlight. They absorb carbon dioxide from the atmosphere and water from the ground, then release oxygen into the atmosphere (photosynthesis!). As a result, hazelnuts are better for the environment than almonds since they are pollinated by the wind rather than bees. Hazelnuts are native to wetter climates, such as the Pacific Northwest, where water is more abundant than in parched California.

Hemp Milk and Flax Milk

Hemp and flax haven’t received the same attention as oat and almond, but they deserve greater recognition for requiring less water, producing high-protein milk, and having a high fiber content. Because they’re grown in such small quantities, they’re referred to as “niche crops.” Seeds, on the whole, are easier to grow than nuts and provide more healthful fats, minerals, and nutrients per ounce.

Soy Milk

Soy is the winner in terms of both sustainability and protein content. And, after years of being misinterpreted as a plant-based phytoestrogen that women avoided because they feared it would increase their risk of breast cancer, new research shows that the opposite is true: that when taken in moderation, soy appears to have some preventive effect. Recent research has indicated that a moderate intake of soy is healthy and may even help regulate hormones.

Soybeans are farmed in huge amounts around the world to feed livestock for meat and dairy production, which is the biggest environmental disadvantage of soy milk. To make space for soy plantations, large areas of rainforest in the Amazon have been destroyed. To get around this, simply do some research and read the label to discover soy milk manufactured from organic soybeans cultivated in the United States or Canada.

Oat Milk

No one could have predicted the love affair that would ensue when the latest Swedish invasion, in the guise of Oatly, arrived in the United States many years ago. Oat milk is strong in protein and tastes much like genuine milk. Growing oats has a modest environmental impact, at least for the time being. Oats are good for both your health and the environment. Also regarded as a low-input crop, oats provide crop diversification, minimize soil erosion, and help reduce the risk of plant diseases when planted in rotation. The magnificent oat is a hero grain in its own right.

Oat milk sales in the United States increased from $4.4 million in 2017 to $29 million in 2019, putting it ahead of almond milk as the fastest-growing non-dairy milk. Oats may become more of a commodity in the future. But, for the time being, there are enough oats to keep us on Oatly for many years.

Oats are typically farmed in mass-produced industrial agribusinesses, where farmers spray them with Monstanto’s glyphosate-based pesticide Roundup before harvesting. As you may be aware, Roundup has been linked to cancer in a number of high-profile cases in which jurors awarded large sums to plaintiffs. Farmers are still aware of the well-publicized occurrences, but they continue to use the chemical because of its effectiveness. Bayer, which purchased Monsanto in 2018, is disputing the active chemical in Roundup, glyphosate, causing cancer in people.

So, how much glyphosate is actually in your bowl of oats or your oat milk latte? Glyphosate was identified in all of the goods tested that used conventionally produced oats, as well as one-third of items manufactured with organic oats, according to a recent study by the Environmental Working Group. The popular Oatly brand oat milk firm, on the other hand, claims that its oats are glyphosate-free.

Pistachio Milk

Pistachio milk, a latecomer to the party, is having a moment in the spotlight. That’s because the rich tiny nuts produce a convincing milk-like flow that goes well with coffee and froths up like real cream in lattes. Tache and Elmhurst both make pistachio milk, which we tasted.

Pistachios are popular not only because they are high in protein and fiber (6 grams of protein and 3 grams of fiber per ounce), but also because they include micronutrients and critical vitamins and minerals such as calcium and zinc, making this nut milk well worth the 92 calories per cup.

If you’re looking for the most environmentally friendly non-dairy milk, you should know that pistachios use half the amount of water as almonds and are on level with oats in terms of water use.

Pea Milk

Pea protein milk consumes less water than other milk substitutes and emits less greenhouse gases than most non-dairy milks. One explanation is that peas use 85 percent less water to grow than almonds, and they can use nitrogen from the air to form plant cells, requiring less fertilizer than other plants, which has a high carbon footprint. “Peas are significantly better on a water and carbon basis,” said Adam Lowry, inventor of Ripple Pea Milk.

Due to its minimal water requirements and the fact that it requires less fertilizer than any other non-dairy milk alternative, pea milk may be one of the most sustainable solutions for your non-dairy milk selections.

Cashew Milk

Cashew milk is the most similar to almond milk in taste and consistency, with one major difference: cashew milk is made with far less water than almond milk. Cashews, on the other hand, are not water-sparing: they require more water to grow than seeds or legumes. Overall, cashew milk is a sustainable option because it requires less area to cultivate the plants, especially when compared to other plant-based milks. Cashews’ demise is due to the mistreatment of cashew pickers. Some people boycott cashews because of the poor working conditions, which include the usage of labor camps in some locations where cashews are farmed and processed for milk.

Macadamia Milk

Macadamia milk uses far less water than almond or dairy milk to develop and create. However, countries where macadamia nuts are regularly grown, such as Australia, Hawaii, and other tropical regions, have been dealing with severe water shortages and other climate-related challenges. As long as pesticides are not utilized, macadamia nuts are considered moderately sustainable because they cause less environmental impact to air, water, land, soil, and forests. If possible, purchase organic and non-GMO Macadamia Milk.

Sesame Milk

Sesame milk is a new plant milk on the market that you may not have heard of but is a terrific alternative if you’re looking for a sustainable option. This non-dairy milk replacement made from sesame seeds may be the most environmentally friendly non-dairy milk on the market.

One of the few sesame milk brands currently on the market, Hope and Sesame, claims that its alternative milk uses 95 percent less water than almond milk and 75 percent less water than oat milk. Drought-tolerant, self-pollinating, naturally pest-resistant, and hardy, sesame plants are native to Africa and India. Pesticides and herbicides aren’t needed for them to thrive.

Sesame milk consumes only 12 liters of water per liter of milk, compared to 28 liters of water for one liter of soymilk, 28 liters for each liter of oat milk, and 371 liters of water for each liter of almond milk. All are superior to cow’s milk, which necessitates the use of 628 liters of water to make one liter of milk.

Which milk uses the least amount of water?

Cow’s milk is far worse for the environment than any of the non-dairy milks. They consume less land, less water, and emit less greenhouse emissions. Because almond trees store a lot of CO2 as they develop, almond milk has the lowest greenhouse gas emissions. However, of all the vegan milks, it uses the most water to make. Soy milk consumes the least amount of water and emits the fewest pollutants.

What is oat milk’s carbon footprint?

One glass of Oat Milk (250ml) equals 0.22kg CO2e or 1.1 kilometers of driving. 0.22kg CO2e is similar to one glass of Oat Milk (250ml). Almond Milk (one glass) (250ml). One glass of Almond Milk (250ml) equals 0.18kg CO2e or 0.9 kilometers of driving.

Which plant milk is the most environmentally friendly?

Soy milk is a joint winner on the sustainability scale, according to the Oxford study. Furthermore, soy is the only plant milk that comes close to matching the protein level of dairy. Long before almond milk became popular, it was the go-to option but then soy fell out of favor.

“People were alarmed because soy contains a rather high concentration of certain hormones that are similar to human hormones,” adds Emery. “But, in reality, you’d have to drink an absurd amount of soy milk and eat so much tofu for that to ever be an issue.” Recent research has indicated that a moderate intake of soy is beneficial to women’s health.

Soybeans are farmed in huge amounts around the world to feed livestock for meat and dairy production, which is the biggest environmental disadvantage of soy milk. To make space for soy plantations, large areas of rainforest in the Amazon have been destroyed. To get around this, simply do some research and read the label to discover soy milk manufactured from organic soybeans cultivated in the United States or Canada.

Which type of milk is the most environmentally friendly?

Soy is the first plant-based milk, after all. Soy was once regarded as the go-to replacement, because to its nutritional benefits and milk-like flavor and texture. Soy milk is supplemented with vitamins A, B-12, and D, as well as calcium, and contains the same amount of potassium and protein as cow’s milk. The following are some disadvantages: Soy is a frequent allergen that contains isoflavones, which are estrogen-like substances that, in high levels, can cause hormone-related health problems such as thyroid dysfunction or fertility troubles. Soy milk production has a low carbon footprint and consumes less water and land in terms of sustainability.

Almond milk entered the food and beverage industry several years after soy, and while many say that it tastes and feels better, its environmental impact is a hot topic. Almond milk has the lowest greenhouse gas emissions and requires the least amount of land to grow, but it needs nearly ten times the amount of water as soy milk. Furthermore, the majority of almond trees are grown in California, which is already prone to drought and heavily reliant on freshwater irrigation. Almond milk has a lot of nutritional value (it’s high in vitamin E and sometimes fortified with calcium and vitamin D), but is the amount of water it uses worth it? You might be better suited looking for a different type of plant-based milk.

Oat milk, a millennial favorite, is becoming as ubiquitous as dairy milk in many major U.S. cities. According to studies, oat milk has a smaller negative environmental impact than almond and soy milk; it consumes significantly less water and land, and emits a fraction of the greenhouse gas emissions. Furthermore, oat milk has the smooth creaminess that many coffee drinkers seek in dairy milk, making it an excellent alternative for both cafs and home baristas.

We’re telling you that there are now barista variants of hemp milk, just as you’ve learned about hemp’s various qualities as apparel and food! Hemp milk is not to be confused with marijuana hemp. Hemp milk is made from the seeds of the hemp plant. Those seeds are a superfood, with as much protein as soy beans, as well as vitamin E, magnesium, potassium, and other nutrients. It has none of the typical allergies, yet because it is a plant, it takes in four times the amount of CO2 that trees do. It also consumes extremely little water and grows naturally without the usage of pesticides.

What foods require the least amount of water to produce?

According to a paper released today by the Institution of Mechanical Engineers, up to 2 billion tonnes of food are wasted each year, accounting for half of all food produced (IME)

According to the IME, 30-50 percent of all food produced (1.2-2 billion tonnes) is “lost before reaching a human stomach.” Rebecca Smithers, a consumer affairs correspondent, writes today:

The Institution of Mechanical Engineers (IME) in the United Kingdom attributes the “staggering” new figures to unnecessarily strict sell-by dates, buy-one-get-one-free deals, and Western consumer demand for cosmetically perfect food, as well as “poor engineering and agricultural practices,” insufficient infrastructure, and inadequate storage facilities.

Food waste has also been blamed on major supermarkets, who have been accused of rejecting crops of edible fruit and vegetables that do not satisfy their stringent physical requirements (such as size and colour). According to the survey, up to 30% of the UK’s vegetable production is never harvested as a result of this practice.

The magazine, titled ‘Global food: waste not, want not,’ also intends to raise awareness about energy, land, and water waste. Humans use over 3.8 trillion cubic meters of water each year, with the global agriculture industry consuming 70% of it. Water wasted in the production of crops that never reach the consumer is estimated to be 550 billion cubic meters globally.

According to IME, the amount of water required to supply food demand in 2050 might be between 10-13.5 trillion cubic meters per year, which is roughly three times the present amount utilized annually by humans.

Meat production demands far more water than veggie agriculture. According to IME, 1kg of beef necessitates between 5,000 and 20,000 litres of water, but 1kg of wheat necessitates between 500 and 4,000 litres.

The table below lists typical values for the amount of water needed to make common foods. Chocolate is at the top of the list, requiring 17,196 litres of water to make 1 kilogram of the product. The production of beef, sheep, and pork meat all necessitates large amounts of water. According to the list, tea, beer, and wine are the least used. Vegetable foods use significantly less water than meat production 1kg of potatoes, for example, uses 287 litres of water.

Take a look at the table below to see how much water is needed to make a variety of common dishes. Also, if you want to see how much water we consume indirectly by eating and drinking different meals, we previously published a fantastic interactive visualization by Angela Morelli, an Italian graphic designer.
