Five Guys, the restaurant folks, get bags of US #1 Idaho Potatoes with the name of the farm owner on them. You can contract for what you want. Generic contracts for commodities won’t have such specifications, nor are such contracts widely traded. But a whole lot of apples get sold, many such contracts will include type of apple, and most produce is sold with contracts specifying minimum standards, usually, in the United States that will be USDA specific standards for that produce.

I don’t think there are futures available for apples, probably because of the amount of variability involved with apples. But as Trom points out, if there was one, it would have strict conditions on the type/quality of apples that can be delivered.
But even if you don’t like the type of apples specified in the (hypothetical) futures contract, you can still use it for hedging. You can buy futures for the standard apple contract, sell them for cash when you need apples, and use the cash to buy the kind of apples you want. If the prices of “the kind of apples you want” and “the contract apples” are well correlated, you’ve effectively locked in your price for the kind of apples you want.
As a real life example, I know at least a couple of airlines hedge the price of jet fuel with crude oil futures. Crude oil is not jet fuel, and the airline would never want to take delivery of crude oil, but the price of crude oil and jet fuel correlate well enough that if the price of jet fuel spikes, the price of crude oil probably also spiked and the airline can sell those futures to offset its additional cost.
