T-45 vs T-90

[Zucker Bee]

(I use a 700 liter~5bbl system)

Is there such a big difference in terms of aroma/bitterness between T-45 and T-90?
Is it worth it for all hops?
Are all hops available in both format?
Is there a significant price difference?

Thank you for sharing your knowledge and experience.

Cheers,

Zb

The T-45 has a chunk of useless plant material removed, so the AA% increases. The Cascade I have been using might come from 6% in T-90 to 9% in T-45. Not all varieties are packaged in T-45 format, in my experience. The main reason for me in using T-45 is to reduce waste in those beers that has a huge pile of hops. Hop pellets retain almost 5L of wort per kg. So if I do a huge IPA with lots of hops, I will go to T-45. Aromatic aspect is not diferent from T-90, although again concentrated.

What is the difference? I mean, how can I tell which kind of pellets I have?

You have T-90 unless you ordered T-45.
