Proizvodnja votke
Pripremanje žitarica i krompira
sastoji se u njihovom usitnjavanju, mešanju sa vodom u odnosu 1:3-4, a zatim razvarivanju na temperaturi oko 150 stepeni u sudovima pod pritiskom od 5 bara.
Razvarena masa se ohladi na temperaturi od 65 stepeni i u nju se dodaju enzimi koji hidrolizuju skrob do fermentisanih šećera.
