Well, cider (and wine) are different than beers in that they are difficult to clone. The reason is actually pretty simple when you think about it. It's pretty easy to taste a beer and say, "Hmmm, I taste cascade hops, vienna malt, etc". Not always easy to actually do, but fairly easy to figure it out.
Cider and wine are totally different. "Cider" comes from any different types of apples. Even cider or juice from the same orchard will vary batch to batch and season to season. Most ciders use tart apples for the best flavor. Each orchard makes their own blend. So, how do you clone something that will never give you an actual list of ingredients even if it was possible to do?
Wine, also. I mean, I can buy some pinot noir grapes and ferment them and press them. But I will never be able to clone Robert Mondavi. The best I can do is buy the highest quality ingredients I can, and the best yeast for the job, and check the ph and hope for the best. I'll have a very nice wine, but it won't be a clone of any commercial winery. There are just way too many variables.
Since I've never heard of Hornsby, I don't know what you're looking for. But you could consider buying a good quality unpreserved cider (NO sorbate!) and then decide if you want it sweet or dry, carbonated or still. You can get a mighty fine cider, as long as you realize it won't be a clone of any commercial cider.
Sorry I'm so long winded! I hope this helps.
