I had a pint of the Grapefruit Slam last night and thoroughly enjoyed it.I was told that it is a Stone Ruination IPA dry-hopped with grapefruit peel to enhance the citrus notes and it works. The citrus gives it a completely different bittering taste and the aroma was very tropical and grapefruity. I'm not positive on the ABV but believe it to be in the high 7% range. The Ruination effect was in full force with this one.
And, as I always like to make notes on how the beer changes as it warms a bit, this one didn't fail there either. The grapefruit aroma was much more pronounced when I got to the bottom of the glass and the citrus was smoother though still complete throughout the sip.
I guess I can sum it up by saying it was a more subtle Ruination but it grabs more attention due to the over the top citrus notes. Since it was kind of dark, I never got a very good look at the true color of the beer but it did have an orange tone to it from what I could tell.
I'd love to have more of this one.

I'm told it was only brewed for the World of Beer event in August so to get a shot at this beer was an honor.

Pretty cool...have you written your clone recipe yet?

Not yet and I didn't think to ask him 'work' type questions for the recipe. I could likely find a Ruination recipe and dry hop with Simcoe and grapefruit peels and get an enjoyable beer.
I may give that a try before the end of the year.

If adding peel for dry hopping, how do you go about sanitizing it? Just put it in vodka for a short time? I'm not talking about zest in the last 2 minutes of a boil, but actually adding grapefruit peel to the fermenter.

I use vodka, everclear, or even Star-san to sanitize fruit/veggies. Don't zest into the vodka though, unless you plan on adding the vodka too. Just sanitize the exterior of the fruit, as well as your zester, and add directly to the beer.

Sounds like an intriguing idea. I made a grapefruit beer very early on (I think batch nine) by adding a bunch of juice. It did NOT work. I was the only one who would drink it. Thankfully, it was in the old MB little brown keg, so there wasn't a whole lot to go through.
