Applejack was hugely popular in colonial America, long before even rye and bourbon came on the scene. Laird & Company has been making applejack (practically right in our backyard) since 1698. There's a reason you might not be exactly sure how to define applejack, and it's because things have changed a bit over time. Historically, applejack was 100 percent apple brandy. And legally that's still the case. But now some versions are blended products. Those are sold under the name blended applejack (though not always obviously so). Laird & Company sells both Straight Applejack, an 86 proof 100% apple brandy that's made in the old tradition — which I would recommend, and blended Applejack, an 80 proof product that's 35% apple brandy and 65% neutral spirits. You'll find lots of other brands, too, of various proofs and descriptions.
