Having now had 3 grapples, let me just say this: I believe a person's reaction to the grapple depends a lot on how much they like apples.
I myself like a crisp, tangy apple. An apple with a bit of zing. Pink lady works. Honeycrisp (although they are typically $1100/pound). Granny Smith (although they are, without a doubt, the hardest apple to tell from the outside what's going on inside.)
I am not wild about Macintosh. Harmony gave me a Cortland apple this week that she had picked herself. It was a beautiful looking Canadian apple but frankly, like macintosh, just kinda bland and mooshy.
Point being: compared to macintosh or cortland, I prefer the grapple. It has a little something going on with it.
However I think I would rather have one of those other apples I mentioned.
We'll see. I have a grapple left so I will have that - then I have some honeycrisps. We'll see how that transition goes.
