I don't know if Conan is patented/licensed/proprietary or not, but the guy at Giga Yeast sure took pains to avoid saying it was Conan/Heady Topper yeast. Here is the exchange:
"I have been trying to get a couple of cans of Heady Topper from the Alchemist Brewery so that I could culture the yeast. Is Vermont IPA Yeast GY054 a reasonable facsimile thereof?
GY054 has properties that make it outstanding for hop forward beers like an IPA. Namely, it leaves a slight residual sweetness that balances hop bitterness and a touch of tropical flavors that are brilliant with aromatic hops. Will your beer taste exactly like Heady Topper if you brew it with GY054? Probably not. There are just too many factors that go into making a particular brew. That being said, if you want a hint of sweetness and some tropical overtones in your IPA you'll be very happy with the results."
A simple yes or no would have been preferred. Ah, such is life.
