Some apples are for making cider. 
These apples may taste bitter or dry. They are not for eating. They have a lot of sugar. This sugar helps make the drink.
Some apples are also very sharp. This adds a bite to the cider. 
Other apples have tannins. This makes a deep flavor. People mix many kinds of apples together. They want a good taste.
Making cider is a special skill.

Cider apples are a special group of apples. 

To make good cider, apples need certain things. They need high sugar levels. This sugar helps the juice turn into cider. They also need tannins. Tannins are parts that add deep flavor. Some apples are also sharp. This means they have high acid. A sharp taste adds a "bite" to the drink.
In 1903, experts in England made a system to group these apples. They looked at acid and tannins. They found four main types. "Sweets" have low acid and low tannins. "Sharps" have high acid but low tannins. "Bittersweets" have low acid but high tannins. "Bittersharps" have both high acid and high tannins. 
Bittersharps can be hard to eat. Some people even called them "spitters." Makers often mix many apple types together. This helps them find a perfect balance. In the U.S., many ciders use dessert apples. These are apples meant for eating. They are often sweets or sharps.
Cider apples are a special group of fruit grown for making cider. 

Making a balanced cider is a careful job. Most makers do not use just one kind of apple. Instead, they blend juices from many different types. This helps them reach a perfect balance of sugar, acid, and tannin. Sharps provide high acid to keep the drink safe from spoilage. Sweets provide the sugar needed for fermentation. 
Experts have used different ways to group these apples for a long time. In 1903, Professor B.T.P. Barker started a system in England. He worked at the Long Ashton Research Station in Bristol. He grouped apples into four main types based on their juice. These types were Sweets, Sharps, Bittersweets, and Bittersharps. 
Each group has its own special traits and names. Sweets have low acid and low tannin levels. Sharps have high acid but low tannin levels. Bittersweets have low acid and high tannin levels. Bittersharps are unique because they have both high acid and high tannin. 
Cider making is a global tradition with many styles. In the U.S., apples are grown in four main regions. These are the Northeast, Mid-Atlantic, Midwest, and Northwest. Many American ciders use dessert apples that are sweets or sharps. In Europe, traditional styles come from places like Normandy in France. 
Cider apples are specialized cultivars grown specifically for the production of cider. 
Successful cidermaking relies on a precise balance of sugar, acid, and tannin. Most producers do not rely on a single cultivar to achieve this balance. Instead, they blend juices from multiple apple categories to ensure a consistent quality. For example, sharps provide high acidity, which helps keep the pH below 3.8 to prevent spoilage. Sweets provide the necessary sugar levels for fermentation to reach the proper alcohol content. 
In 1903, Professor B.T.P. Barker established a formal classification system in England. He served as the first director of the Long Ashton Research Station (LARS) in Bristol. His system categorized cider apples into four main types based on tannin and malic acid percentages. The first type is "Sweet" (SW), which has low acid (<0.45% w/v) and low tannin (<0.2% w/v). Examples include the Sweet Alford and Sweet Coppin varieties. Most dessert apples also fall into this category. 
The second category is "Sharp" (SH), defined by high acidity (>0.45% w/v) but low tannin (<0.2% w/v). These apples, such as the Crimson King or Tom Putt, can add a "bite" to the cider. The third category is "Bittersweet" (BSW), which features low acid (<0.45% w/v) and high tannin (>0.2% w/v). Many bittersweet cultivars, like Dabinett or Yarlington Mill, have European origins. They were often called "French" or "Norman" in English cider counties. The fourth category is "Bittersharp" (BSH), which contains both high acid (>0.45% w/v) and high tannin (>0.2% w/v). Because they are naturally unpalatable, bittersharps have historically been called "spitters." Varieties like Kingston Black are particularly suitable for making single-varietal ciders.
Different regions have developed their own unique ways to classify these fruits. The Long Ashton system also used a three-level scale for tannins: "full," "medium," and "mild." For instance, Chisel Jersey is considered a "full bittersweet." In France and Spain, classification systems include an intermediate category. In France, this is called "acidulée," and in Spain, it is "acidulada." These systems categorize apples that are semi-tart and have low tannin content. They continue to use acidity and tannin levels as the primary metrics for sorting varieties.
In the United States, cider apples are grown in four distinct regions. These include the Northeast, Mid-Atlantic, Midwest, and Northwest. Out of the twenty most common cider varieties grown in the U.S., half originate from England. Two varieties come from France, while the rest are American. Because high-tannin cultivars are less readily available in the U.S., many American ciders are made from culled dessert apples. These are generally a mix of sweets and sharps. There is currently no systematic classification for North American cider cultivars, though the U.S. National Plant Germplasm System (NPGS) maintains a database of apple varieties.
Cidermaking involves complex chemical measurements beyond simple flavor. Professionals look at pH, polyphenol composition, and soluble solid concentration, measured in degrees Brix. The Brix level helps quantify the potential alcohol that yeast can ferment. This is important for following tax regulations. In the U.S., hard cider falls into a tax bracket between 0.5% and 8.5% alcohol by volume. If a cider exceeds 17 °Brix, it may be subject to higher taxes as a "cider wine."
