Manufacturing of Havarti Cheese.

Process guidelines for Havarti 45+
(blocks/loafs of approx. 2.5 kg)
 
Raw material               raw milk
 
Standardization to 2.9 – 3.5 % fat  depending on the protein content
 
Heating                       72 – 75 C (161 – 167 F) for 16 – 30 sec. or
                                    145 for 30 minutes.
 
Cooling                       to renneting temperature: 30 – 32  C (86 – 90 F).
 
Inoculation                 0.7 – 1 % Probat 505 bulk starter or Probat 222 (50 DCU / 500 Lt. 130 gal. - direct set)
 
Addition of CaCl2      approx. 20 gr. / 100 Lt. (optional)
 
Preripening                  to pH 6.50
 
Renneting                    2 – 3 gr. pure calf rennet powder (Renco) or RenNet 1 gr/100 Ltr
 
Coagulation                 setting time:           15 – 18 min
                                    Coagulation time : 30 – 40 min.
 
Cutting                        curd grain diameter: green pea to hazelnut size
                                    (approx. 0.5 – 1 cm3)
 
Setting                         5 – 10 min.
 
Stirring                        20 – 30 min.
 
Separating                   draw of whey, 30 – 40 %
 
Stirring                        10 –15 min.
 
Scalding (cooking)      addition of water: 15 % +- 3 % of hot water (temp. depending on amount of vat milk)
                                    Scalding : to 38 C (100 F) , within 15 – 25 min.
 
Final stirring                40 – 50 min. (addition of 100 – 200 gr. of NaCl. / 100 Lt. cheese milk if dry salting is desired).
 
Filling                          into forms (hoops)
 
Pressing                    depending on equipment, e.g. 15 min. 0.3 – 0.6 bar (1 bar atmospheric pressure)
                                    Room temp. 25 C, frequently is not pressed but just turned, thus pH of the cheese must be 5.3 +-0.15 before brine bath and 5.505 +- 0.1 after brine bath)
 
 
 
Brining                        pH before brine bath : 5.2 +- 0.1
                                    21 +- 21 °Beume, 15 +- 3 C (59 F), pH 5,05 +- 0.1 (can be more acid than the cheese) concentrated salt solution
                                    salting time : 24 – 54 h. depending on weight
                                    pH after brine bath : 5.10 – 5.15
 
Smearing                   dipping or spraying red smear solution (liquid culture in 5 volumes of 3 % NaCl solution), during initial ripening smearing must be repeated twice. Use B. linens.
 
Ripening                      The first two weeks at 15 +- 3 C, 95 – 100 % RH (relative humidity)
                                    Cheese must be treated with red smear twice a week until a nice closed but not too thick layer of redsmear has developed.
                                   (B. linens)
                                    The next two – 6 weeks at 12 – 14 C, 85 – 90 % RH.
 
Packaging                    After washing and drying
 
Storage                        at 6 C
                                    Mild type       > 5 weeks
                                    Medium           > 3 month
                                    Sharp               > 6 month
 
Production of bulk starter:
 
Medium              Skimmilk
 
Heating                       at 90 – 95 C ( 194 – 203 F) for approx. 30 min.
 
Cooling                       to 22 C (72 F)
 
Inoculation                 1 x Probat 505 Visbyvac B 1000 per 1,000 Lt. (264 gal.)
 
Incubation                   at 22 C (72 F) in 18 h. to pH 4.65 +- 0.10
 
Cooling                       to 4 – 8 C (39 – 46 F)
