I try to read a lot from the hops before use, see how ppl taste and smell after using, this will not get a accuracy parameter, because of the haverst time, store temp and duration, and other things, but if I have a hop that I really want to test there 3 option, for me, use a SMaSH beer with a malt I use a lot, for me is or pilsen malt from the swaen or ale from the swaen too, I did a nelson sauvin SMaSH, but if I want want something not so "boring" I use a recipe that I already did numerous time and this divide in 2 option, the first one replace my hops to the new one, I did a best bitter trying to test green bullet this way, or add the new hop in the recipe and see how they work together, I did a Indian Pale Lager testing loral hops with cascade. The best one to see how the hop behave is the SMaSH one but you can try other ways too
