But even here, alarm bells are ringing. Castle Creek, described as a “wine fruit product” contains not only sulfites but also milk and egg. Presumably, these are added during the process of fining, whereby impurities and solids are removed from the bottom of the fermentation tank. While it is reassuring that these additives are at least mentioned, as they are in another fine red wine with fruit juice called Brookford, there is no reference to their possible role as allergens. Milk and egg are two of the world’s top eight causes of allergic reactions.
