Cranberry juice is a bright red drink. 
Cranberry juice is a bright red drink. It comes from the cranberry fruit. These berries have a very tart taste. Because they are so sour, many juices add sugar. Some juices also mix in other fruit juices. These blends often use apple, pear, or grape juice. 
Farmers grow cranberries in places like Canada. One common way to pick them is called wet harvesting. In this method, machines use water to help collect the berries. 
Many people drink this juice for health reasons. Some think it helps prevent urinary tract infections, or UTIs. This is a type of infection in the body. Scientists are still studying this. Some studies show it might help certain people. Other studies say the evidence is not clear.
Cranberry juice is also very acidic. This means it has a low pH level. This acid can sometimes wear down tooth enamel. Most juice also has vitamin C added to it. This helps keep the juice fresh.
Cranberry juice is a bright red liquid made from a tart fruit. People enjoy it in many different ways. You might find it as a pure juice or a dried snack. It can also be a thick sauce or even a powder. Some people drink a blend called a cranberry juice cocktail. This blend usually has about 28% cranberry juice. The rest is often water and other juices like apple or grape. Sugar is often added to make the sour taste better. 
Making this juice is a very careful process. Most juice comes from the American cranberry. Farmers in Canada grow these in places like Nova Scotia and Quebec. They often use a method called wet harvesting to pick them. A machine called a water reel harvester uses paddles to shake the berries from the vines. Then, a large suction pipe pulls them up. The berries go to a plant to be crushed and heated. Finally, they are pressed to make a concentrate. 
There is a long history of people using cranberry juice for health. Many believe it helps prevent urinary tract infections, or UTIs. Scientists have studied this for a long time. In 2008, some evidence suggested it might help. However, a study in 2012 said it was not as effective as people thought. A review in 2017 showed it might help people with infections that keep coming back. By 2023, researchers found it might help children and some women. Still, the evidence is not the same for everyone. 
There are many interesting facts about what is inside the juice. A single cup of fortified juice has 107 calories. It is mostly water, which makes up 86% of the drink. It also has 11% carbohydrates. Most juice has vitamin C added to keep it fresh. This juice is very acidic with a pH of about 2.6. This high acid level can sometimes wear down tooth enamel. Because of this, some juices use sweeteners to change the taste. 
Companies use special ways to keep the juice safe to drink. They often use heat to kill tiny germs that cause spoilage. This is called thermal processing. Some new methods use high pressure instead of heat. This is called high pressure processing, or HHP. It uses 80,000 psi of pressure to clean the juice. Another way is using a pulsed electric field, or PEF. This uses electricity to stop harmful microbes. These methods help keep the color and flavor just right. 
Cranberry juice is a bright red, acidic liquid made from the fruit of the cranberry plant. It is widely used to create many different products like dried fruit, sauces, and dietary supplements. While pure juice is very tart, many people enjoy cranberry juice cocktails or blends. These blends typically contain about 28% cranberry juice. The rest of the liquid usually consists of water and other fruit juice concentrates, such as apple, pear, or grape. Manufacturers often add sugar to these blends to make them more palatable for consumers. 
Most commercial cranberry juice comes from the American cranberry, known scientifically as *Vaccinium macrocarpon*. Large-scale farming occurs in several Canadian provinces, including British Columbia, Québec, New Brunswick, Nova Scotia, and Prince Edward Island. In the eastern provinces, farmers must use irrigation and flooding to protect crops from frost. To produce juice, farmers often use a method called wet harvesting. A machine called a water reel harvester uses paddles to separate the ripe berries from their vines. A large suction pipe then collects the fruit to be sent to a processing plant. 
At the processing plant, the berries undergo a specific sequence of mechanical steps. The fruit is crushed and then undergoes mash maceration and heating. After the mash is heated, the juice is pressed out and pasteurized. This process creates a cranberry juice concentrate that is separated from the pulp. To make a finished juice product, this concentrate is reconstituted with specific amounts of water. This method ensures that the final product meets the requirements of the purchase orders or contracts. 
To keep the juice safe, manufacturers must eliminate pathogenic or spoilage-causing microorganisms. Traditionally, this is done through thermal processing, which uses high temperatures for short periods. These techniques are known as high-temperature-short-time (HTST) or ultra-high temperature (UHT) processing. This heat treatment is designed to achieve a 5-log pathogen reduction. Because cranberry juice is highly acidic, with a pH between 2.3 and 2.9, the bacterium *Clostridium botulinum* cannot grow in it. However, newer methods like high pressure processing (HPP) have emerged. HPP applies 80,000 psi of pressure for one to nine minutes to eliminate bacteria, molds, and viruses without using heat. 
Another modern technique is pulsed electric field (PEF) technology. This method uses a high-intensity electric field to create a flux of electric current through the food. PEF is useful because it does not alter the aroma, color, or flavor of the cranberries like thermal processing can. Once processed, the juice is packaged in aseptic, hermetically sealed containers like cans, cartons, or plastic bottles. These containers must be filled to at least 90 percent capacity. For example, brands like Ocean Spray and Fruit d'Or have frozen shelf lives of 24 and 36 months, respectively. 
There is much discussion regarding how cranberry juice affects health, specifically urinary tract infections (UTIs). For many years, people believed the juice could prevent these infections. However, scientific reviews have shown inconsistent results. A 2012 review suggested the juice was less effective than previously thought. By 2017, one systematic review indicated it might help people with recurrent infections. A 2023 review found evidence that it may reduce UTI risk in children and women with recurrent infections. However, there was little evidence of an effect in pregnant women or the elderly. 
Because the scientific evidence is not always certain, the FDA has specific rules for labeling. In 2020, the FDA allowed a "qualified health claim" for certain products. This claim can state that drinking 8 ounces of juice daily may help reduce the risk of recurrent UTIs in healthy women. However, the label must include a disclaimer stating that evidence is limited or inconsistent. This is different from an "authorized health claim," which requires much higher scientific agreement. 
From a nutritional standpoint, cranberry juice is composed of 86% water and 11% carbohydrates. It contains less than 1% fat or protein. A standard 8-ounce serving provides 107 calories and is often fortified with vitamin C to maintain freshness. One half-cup serving provides 20% of the Daily Value for vitamin C. It is important to note that the juice is very acidic, with a pH of approximately 2.6. This high acidity level can potentially erode tooth enamel over time. Additionally, products with high sugar content may affect blood glucose control in people with diabetes.
