Well, as you say, back then alphas were largely what they were looking for. I think the general attitude towards hops has greatly evolved over the last few decades, and that a lot of things on the market now would never have been adopted if we go back in time.
CRV might be lacking in alphas compared to super alpha varieties... but 5% is by no means "low". I can't say for this one specifically, but I think that a lot of the older cultivars that never really picked up back in the days would have had a better chance at it today, where a "different" aroma or taste is no longer considered a serious flaw. That said, CRV is said to be susceptible to mildew, and I've never really seen any praise for its aroma, so...
I'm curious, though. Why do you need Canadian Red Vine for your project?
