I have some Perle hops, but have never used this variety before. Was thinking of doing a german pils using all Perle hops. Just looking for some feedback on this hops and if they will be suitable for a pilsner?
I’ve only ever used them in a German Weizen, but I think they would work well in a Pilsner
I made a single hop IPA a bit ago with Perle hops. It was pretty good, didn’t use as much hops as I’d have liked, but I don’t see any reason why you can’t use them in a single hopped beer of any kind.
Not my favorite hop but they would work well in an all Perle Pils. Perle are kind of minty to me. I prefer Mittlefrue or Hursbrucker. But if you have 'em, use em. No better way to learn the taste of a particular hop that by trying the exclusively.
Where do you get Mittelfrueh?
Don’t know if anyone is carrying it. Right now, I mostly have Hersbrucker. I have heard it say that most times when a GR hops is simply named “HALLERTAUER” it is mittlefrueh.
Perle is a true dual-purpose hop that will lend a pleasant spiciness to any beer. They lack some finesse compared to their Noble Euro counterparts, so they’re maybe not the best choice for late editions but will do just fine in a pinch. I’d recommend using them sparingly towards the EOB with more mid-boil emphasis which is mostly how I use them. Good luck! 
Thanks for all of the input, I’ll let everyone know of the pils turns out.
hopsdirect.com has it (though be careful, still 2008 crop).
I emailed them prior to purchase and they confirmed that they are indeed mittlefruh - and I have heard before from other sources the same that keith mentions above - that if its not specified, its mittlefruh.
Perle worked very well as a bittering hop in my last german pils, but it does lend a distinctive bittering character that falls somewhere between minty, fruity pebbles, and Sierra Nevada.
I haven’t used it for flavor/aroma in a Pils.
This guy on the Homebrewtalk wiki disagrees.
Wow, this wiki is really coming together over there.
He is correct in saying that “halletauer” is part of the cultivar name. Right now, for example I use hops that were labeled HHT on the bag. This 3 letter abrevation is standardized for German hops. In my case it means Hallertau Hallertauer Tradition. The first letter is for the growing region and the last two are for the cultivar name. But when we buy hops we are generally not exposed to this labeling. Too bad.
Hops labeled Hallertauer can easilly be Hallertauer Tradition as well. I don’t think it will ruin the beer if you get Tradition instead of Mittelfrüh, but there is some ambiguity.

I really like Perle in an Alt. I tried them as bittering hops for a Koelsch, it was ok, but not great.
