I enjoyed this... it was very smooth for such a big beer. That's a ton of hops  :rock:

I should mention this is a clone of Maine Beer Company's DIPA called Dinner. The recipe actually broke down to call for a full pound of dry hops! But I scaled it back to half that.

Two Wheeler

Haha, yeah that's an expensive dry hop.

That makes me wonder... where is the point of diminishing returns on dry hopping? You would think at some point the flavour/aroma is going to max out and then you're just losing beer to the hops.

Exactly. Even half a pound is likely past that point.

Interesting combination of hops. Looks great. :)

Tastes great too.  :cheers:

It was the first time I had used Falconer's Flight. Really impressed by the flavor and aroma.

Did you actually boil for 90 minutes with that much pilsner?

No, it was a 60 minute boil. Did I put 90 minutes somewhere in the recipe? I can't seem to find that written anywhere.

Oh no, I was just curious. Pilsner is usually boiled for 90min, so I just assumed...lol

robcoombs

Actually I didn't know that. It's only the second time I've used pils.

I love pilsner malt myself, sucking back a glass of a German pils I made 6 weeks ago. Only reason 90 minutes for pilsner is it drives off DMS which gives you that cooked corn flavor. But I doubt you are gonna notice any of that with that hop bill. It does sound really good, would have liked to try it.

robcoombs

I only have 5 bottles left. Definitely the fastest I've gone through a batch.

I have experimented a lot with dry hopping and finding the point of diminishing returns, generally speaking, the following applies, per 5 gallon batch, using pellet hops:

- 1oz is subtle
- 2-3 oz per dose is usually best bang-for-buck
- 2 * 2oz dose, five days apart is more effective than adding them all at once
- pay close attention to water chemistry, for example Freddy city water needs approx 3Tbsp gypsum in the mash water to really make the hops "pop"
- careful with amarillo and citra: too much of the first gives you a mayonnaise aroma, too much of the second may give you a magic marker aroma
- add a dose of dry hops to the keg, in a muslin bag
- 12oz of fresh (current year's crop) pellet hops, added in doses of 3oz at a time, the first 3 doses free floating, and the last dose in the keg, in a bag --> is at the far end of the point of diminishing return. I have incrementally added more hops, up to 2 pounds in a 5 gallon batch, but aside from giving the beer a green tinge, there was no real noticeable effect.
have a very large dry hop bag, or let them float freely (they will sink after a few days)
