Please answer this contract question I have.

5. Sarah is a farmer who grows organic hops, the flower flavoring agent that gives beer its bitter flavor. Brian operates an organic craft brewery in Brooklyn. They entered into a contract for the sale and purchase of 1,000 bushels of organic Chinook hops for November 1 delivery at a price of $1 per bushel. In August, an infestation of aphids attacked Sarah's crop. Adjacent crops were spared because the growers used pesticides. Sarah notified Brian that her crop had been destroyed and that he needed to make other arrangements. At that time, the per bushel price of organic hops was $2. The following day, Brian purchased 1,000 bushels of organic hops from another grower at $2.50 a bushel for November 1 delivery. Did Sarah breach the contract? If she did, what can Brian recover in damages
