I'm not sure why Cabot doesn't suck it up and go OU Kosher year round, especially after my horrifying incident with their hashgacha, Tablet K, over the summer in Middlebury, Vermont, but at least they have the decency to run a limited production of OU Kosher for Passover Sharp Cheddar Cheese once a year. ONCE a year, folks. One of the local shuls is doing a fundraiser, and on the Cabot website they even tout the option of selling their cheese as a fundraiser.
So go buy some. And then write a letter to Cabot begging them to sell the business of kashrut to the OU permanently!
