I used 6 gallons of skimmed raw jersey milk from our cows. Then I noticed that I was supposed to use full fat milk so I added 2 quarts of the cream I just skimmed back to it. The final cheese weighed 6.37lbs. I used a 8.25" diameter Tomme mold.
For further comparison. I made a colby yesterday using 6 gallons of milk and the cheese is only 5.5lbs roughly.
