Strongbow doesn't call itself a cider because......it isn't.
More chemical than apple, methinks...
Strongbow
is a cider. It's referred to as a cider by Bulmers in their marketing. And to do that it has to meet legally required conditions to be referred to as cider. Typically the only 'chemicals' that are added are as preservatives. Far, far less than the apple juice content.
It is fermented apple juice (from a mix of bittersweet cider apples and culinary apples), water, glucose syrup, lactic acid (preservative), citric acid (acidity regulator) and potassium sulphate (preservative).
For a drink to be defined as cider it has to contain a minimum of 35% apple juice. Even mass produced ciders such as Strongbow typically contain more than this. That said, the mass produced ciders do derive a lot of their alcohol content from the fermentation of the added sugars (glucose syrup typically) rather than the fermented apple juice.
None though are 'more chemical than apple'. For that to be true the added preservatives and acidity regulator would have to total more than 35%.
Bulmers Original will have similar ingredients. What typically differentiates one mass produced cider from another is the apples (or blend of apples) used and the percentage of apple juice. They will all contain preservatives, additional sugars and water.
