From what I gather hops are very difficult to identify. They look similar to a herloom variety that I have growing. I would reccomend tasting them as well. You should be able to determine a good idea of whether they are a bittering hop or an aroma hop by how bitter they taste. I would taste a variety that you know the alpha acid content on then taste yours. If it's more bitter than you know it has more alpha acids than that variety. Do the same for smell and that'll give you a general idea of what it comes close to. I would then use it accordingly. I would find a good recipe and just adjust quantities based on your best guess of alpha acid content.
Otherwise I can offer up this info -- The Hop Growers of America sent me this when I was in search of what variety I had...
"Identifying a variety of hops is difficult, particularly with heirloom varieties that are no longer produced commercially (or may have never been commercially produced). Researchers could do a PCR analysis to try to match the DNA to a known variety, but that is a pretty costly process. It also requires that the variety has already been characterized regarding the DNA fingerprint. As you already know the hops in question are probably an old or wild variety that someone moved to that location, it is highly unlikely that the DNA fingerprint would match any current commercial variety that has been characterized. Unfortunately, modern breeding programs have created a whole range of relatively new commercial varieties that are now demanded by brewers (virtually everything we grow has been released in the past 30 years). You indicated that you are testing some in your own pilot brew, so you may wish to just brew and enjoy! You may have the next "Local Heirloom Hop Ale" to share with your friends!
If you want a brewing value profile (although this won't pinpoint variety), the Washington State Dept. of Agriculture's Hop Laboratory in Yakima, WA offers this service for a nominal fee. You are welcome to contact the Hop Lab's manager, Royal Schoen, at [email protected]
to discuss the brewing value testing that they offer."
Hope this helps!!
