The Greyhound

The Greyhound is another of the New England highballs, a variation on the Cape Codder that uses grapefruit juice instead of cranberry

In a highball glass, combine
Again, the proportions are variable. If you like more vodka taste, add more vodka. If you like more sour, add more grapefruit. For some drinks, I'm a stickler about proportions. I wouldn't advise adding an extra 0.5 oz. to a Vesper, for example. But the New England highballs aren't those drinks. Vary them all you want according to your taste.

And as long as we're talking about taste, I'm actually not a huge fan of the Greyhound. Last time, I talked about the Sea Breeze, which combines vodka and cranberry with 1 oz. of grapefruit juice, and that drink works perfectly. But the Greyhound is only grapefruit, so there is no sugar to balance out the sour. One commenter said they like to order Cape Cods at office parties, and I can see that. I wouldn't order a Greyhound.

 A note about grapefruit juice: I have been using fresh grapefruit juice. It's December, so grapefruits are in season in Texas, and I can buy a 10 lb. bag for $3. That 10 lb. bag will give me about 5-6 cups of juice after lots of squeezing. So I don't recommend these for everyone at a party unless you use bottled grapefruit juice. And bottled grapefruit juice may actually be better because it probably isn't as sour as the fresh stuff. But I don't really know. In general, fresh is better, so I'm sticking with that.
