Explain, in three or more paragraphs, the dairy process at Bonnie Blue Dairy. Also, explain components of the cheese making process and at least two types of cheeses made by the dairy.

A

Bonnie Blue Farm is a goat dairy farm. They raise two breeds of goats, Saanens for their high milk production, and Nubians for their higher butter fat content. They hand milk some of their goats. This milk is used to feed their baby goats. The rest of the goats are milked using a automatic milker. This milk is used to produce goat cheese.

 Once the goats have been milked, the milk has to cool up to 72 hours. When it is time to make cheese, They transfer the milk from the big tank into smaller stainless steel tanks. Next they take the smaller containers into the cheese studio to get pasteurized.

 In the cheese making process they use a cheese knife to separate the whey from the cheese curd. Once the curd is separated from the whey, the curd drains overnight. The cheese made in these tubs will eventually be packaged as feta cheese. Bonnie Blue Farm produces over a dozen different products including goats milk, feta, and raw milk cheeses, some even award winning.
