I'm still going with grapes. Your big guys can squash them all you want. Then all I have to do is ferment them and then who's the big winner now?
Back to the orange and apple. I have to go with orange. It's a better tasting fruit, it's a better tasting drink, it's a better flavor Popsicle, sherbet, hard candy, soda, and yogurt. And it's juice tastes so good with a bottle of Bacardi Anejo rum or a bottle of Grey Goose vodka.
All apples have going for it are apple pie and hard apple cider.
Heck, when picking oranges you are usually in Florida or California. To pick apples you usually have to be in a colder state with worse weather.
