A common practice used by "large" companys:
1. Ferment the fresh pressed apple juice (with or without concentrated juice) as a strong apple wine (about 13% alcohol).
2. Store in Large, chilled concrete vats that occupy about half your site.
3. Dilute with water and carbonate as required.
4. Keg or bottle the dilute cider as required by market.
5. Optional: Add all sorts of fruit flavourings and sweetners
