Nugget vs. Magnum hops as a generic/universal bittering addition hop choice?

This makes sense. Chlorophyll is also pretty bitter, it’s largely what makes certain vegetables so bitter. No doubt that is part of the “stuff” getting extracted as well.

I don’t know that it’s not,  but I’ve never seen chlorophyll mentioned in any research.

im no expert on tannins or oak, etc.

but i was listening to an MBAA pdocast on oak with some oak barrel experts. they stated that french oak has an average of 10% tannins, american oak an average of 2%. then a minute later they said “american oak has a much harsher effect”.

i dont directly connect tannin = harsh, but i thought it was so to a degree, or bitterness/astringency, etc

it confused me.

I still get a similar harshness out of Cryo hops (although not quite at the same intensity) when whirlpooled at 140F. If chlorophyll was a primary contributor, I would expect this character to be greatly diminished when using Cryo hops compared to traditional ones.

I’m not sure I follow this logic. All that other “stuff” is in the vegetal part of the hops. Using cryo hops will commensurately scale down the amount of all of this stuff, not just chlorophyll.

Tannins are definitely harsh in sufficient quantity. That’s where the burn in hazy IPA comes from.

I’m surprised since the harshness comes from tannins in the bract and nearly all the bract has been removed from cryo.

If we haven’t identified what all the “stuff” is, how can we be sure that it isn’t coming from the lupulin? Ever taste unboiled hop shot? It has a very similar rough bitterness to what I get from whirlpool hops. I don’t doubt that the vegetative matter contributes some harshness, but I’m not convinced that this is where all of it resides.

I doubt that hop shots are only lupulin.

dont get me started on the wine industry and its ridiculous bias against American Oak.

I use magnum for all my porters and stouts,  and have liked it.  Is it possible that some other issue caused your dislike of the results?

Porters and Stouts do not to me represent the sort of beers that receive appreciable dosing of flavoring and/or aroma hop additions, let alone dry hop additions.  I consider Porters and Stouts to be nigh-on perfect candidates for Magnum hops, simply for the reason that these two styles (in my opinion, which likely reflects my age) are well suited to mainly bittering only hop additions.

I agree that Horizon is a great bittering hop, but hard to get in Canada.
