Over the holidays, I made 2 goudas using Pav's recipe. Both makes went pretty much identical, but the PH targets were slightly different than Pav's recipe. Overall, I've very satisfied with how both cheeses and plan to age them around 18 months.
Here are the details:
8L 0% P/H skim milk
680 ml 35% unhomogenized cream
Total fat content: about 2.74%
1/8tsp MM100
1/8 tsp Aroma B
1/2 tsp CaCl and Single str animal liquid rennet
22% adjusted brine
PH targets (both almost identical):
At start: 6.73
At rennet and draining (no drop in both cases): 6.60
Final PH after last press: 5.55
I also did a 15 minute light press in the whey with both.
All other presses were done at 4.86PSI. Total of 4.5 and 5 hours of pressing.
Air drying : both around 7-8 days at 13-14C and 80-85% RH
Aging, Phase 1: 10-11C at around 60-70% RH, 3 coats of cream wax for 1 or 2 months (currently at this stage. Not sure how long I'll let rind develop)
Aging, Phase 2: 10-11C vac sealed for the remaining long year and a half.
I'm trying to keep the temp closer to 10C to limit eye development.
I'm pretty confident I won't have any problems waiting out the 18 months. I like old Gouda too much (18-26 months)! I wouldn't want to spoil it.
