How Much Water Is Used To Make 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.

How much water does a glass of oat milk require?

To make oat milk, just combine 1 cup rolled oats with 4 cups water in a high-powered blender for 30-45 seconds on high. For optimal results, strain through a clean t-shirt or towel.

We discovered that nut milk bags allowed too much pulp to pass through. We don’t recommend using fine mesh strainers since they let too much pulp through.

This method consistently produces creamy oat milk that’s great in coffee, matcha, cereal, oats, baked goods, granola, and more!

Is oat milk better for the environment?

Around 0.18kg of CO2e is produced by a 200ml glass of oat milk. That’s a lot less than soy or cow’s milk, for example. Overall, oat milk production emits 80% fewer greenhouse gases than cow’s milk, so you can feel good about your carbon impact whenever you pick oat milk.

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.

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.

Is oat milk more environmentally friendly than cow’s milk?

Have you seen a shift away from animal dairy products like cow’s milk and toward plant-based alternatives? Vegetarianism and veganism are becoming more popular for a variety of reasons, including environmental concerns, food intolerance or allergies, religion, or simply a personal preference. There’s also data to show that eating a plant-based diet will help you live longer.

Oat milk is a popular plant-based’milk’ choice, probably because it has a smaller environmental impact. When compared to cow’s milk, oat milk produces 80 percent fewer greenhouse gas emissions and consumes 60 percent less energy. Oat milk is also ten times less water intensive than cow’s milk.

Despite the fact that oat milk looks to have numerous advantages, how does it fare nutritionally?

The importance of protein

Oat milk is far lower in protein than cow’s milk. To receive the same amount of protein from oat milk as we do from cow’s milk, we’d have to drink more than twice as much every day.

As we age, it’s critical to consume adequate protein to retain lean muscle mass. It’s also true that as people become older, their capacity to digest protein declines; women and men over 70 require 20% more protein than younger folks. Being aware of protein sources in the diet is beneficial for several reasons.

Calcium recommendations

Dairy products are vital in our diet because of the calcium they supply – today, less than half of Australians eat the required amount of calcium in their diet.

Calcium is necessary for the healthy functioning of the heart, muscles, blood, and nerves, as well as for the maintenance of strong bones. When the body doesn’t get enough calcium from food, it pulls calcium from the bones and puts it in the bloodstream to keep things running smoothly. This can develop to osteopenia (low bone mass) or osteoporosis over time (low bone density). This indicates that the bones are not as robust as they should be, raising the chance of fracture.

The recommended daily dose for younger persons is 1000 mg; for women over 50 and males over 70, the recommended daily intake is 1300 mg. Because plant-based milks are low in calcium naturally, they are sometimes (but not always) calcium supplemented. Look for brands that include at least 120mg of calcium per 100ml to be comparable to dairy milk.

Fat facts

While oat milk has a lower protein and calcium content than cow’s milk, it also has a lower saturated fat content. One of the reasons why some people believe it is a healthier option is because of this. If your cholesterol is normal, full cream milk, yoghurt, and cheese can be part of a balanced eating pattern, according to the Australian Heart Foundation. Reduced fat dairy is a healthier choice if you have excessive cholesterol or a history of heart disease.

What kind of milk is the most ethical?

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.
