Mahl kui siidri tooraine peab vastama kindlatele nõuetele: olema sobiv suhkrusisalduse, parkainerohkuse, kiudainekülluse ning orgaaniliste hapete poolest, sest nendest oleneb suuresti lõppsaaduse kvaliteet.
Worldwide, cider varies in alcohol content from less than 3% alcohol by volume (ABV) as found in French cidre doux, to 8.5% ABV or above in traditional English ciders.
