My first Gruyere was very disappointing. It was very smooth and creamy and about bland as bland could be--even after 6 months ripening! It did not taste like gruyere! After rummaging thru threads on this site I saw that this recipe really needs Propionic bacteria, even though book recipes don't list it. So here we go for a second try!
4 gallons raw cow milk pH 6.7
¼ tsp TA
¼ tsp LH
¼ tsp PB
24 drops triple strength rennet
Warmed milk to 90 degrees, added cultures and let them rehydrate 5 minutes. Stirred and let milk ripen for 10 minutes.
Added rennet, stirred and let sit 40 minutes. Floc at 16 x 2.5 = 40 minutes.
Checked for clean break and cut curd into rice sized pieces with a whisk. Temp 90 degrees
Returned to heat and raised temp to 114 degrees over 60 minutes (ended up hitting 114 in 45 minutes so I just stirred the last 15 minutes at 114 degrees). pH 6.5
Let sit 5 minutes, drained and hooped. pH after hooping was 6.4. Pressed for 1 hour at 35 lbs, redressed and pressed at 110 lbs overnight.
Placed in brine for 12 hours, then removed to air dry before going to my cave.
The cheese looks good and the trimmings from the edges tasted good. I really need do more to eliminate press marks from excess cheesecloth!
