A quintessential brewing ingredient, hops are sometimes dried after being harvested, at which level they’re prepared for use. Traditionally, complete cones have been the usual in brewing, although over time, numerous different hop kinds have been created with the overarching purpose of brew day optimization, the preferred of which is the T-90 pellet.
Put merely, T-90 pellets are created from pulverized hops that get pressed by a pellet die and retain roughly 90% of the entire cone weight, therefore the title. Along with taking on much less house and being simpler to handle, T-90 pellets extra readily drop out of answer, making a layer of trub that may simply be left behind when transferring wort or beer out of a vessel. A more moderen growth is LUPOMAX hops, which look just like T-90 pellets although have a a lot increased focus of lupulin with much less vegetative matter, permitting brewers to make use of round 30% much less whereas attaining comparable efficiency ranges.
I by no means had a lot of a difficulty with T-90 pellets, however I’ve used LUPOMAX hops fairly a bit and my expertise has been extremely constructive. With a previous xBmt exhibiting tasters may reliably distinguish an American Pale Ale made with T-90 hops from one made with LUPOMAX hops, I used to be curious if dry hopping an IPA with LUPOMAX on the really useful utilization price could be perceptibly completely different than dry hopping with T-90 pellets and put it to the take a look at.
| PURPOSE |
To guage the variations between an American IPA dry hopped with both El Dorado T-90 pellets or LUPOMAX pellets.
| METHODS |
For this xBmt, I designed a easy American IPA recipe that I felt would permit any variations between the beers to shine.

After gathering the water for a single 10 gallon batch, I weighed out and milled the grain.
With the water correctly heated, I integrated the grains then checked to verify the mash was at my goal temperature.
Throughout the mash relaxation, I ready the kettle hop additions.
As soon as the mash was completed, I batch sparged to gather my goal pre-boil quantity then proceeded to boil the wort 60 minutes, including hops on the occasions listed within the recipe.
When the boil was full, I rapidly chilled the wort.
Subsequent, I transferred equivalent volumes of wort to separate fermenters.
A refractometer studying confirmed the wort was at my goal OG.
16 °P = 1.065 OG
The fermenters have been linked to my glycol unit and allowed to complete chilling to my desired fermentation temperature of 68°F/20°C, at which level I pitched a single pouch of Imperial Yeast A07 Flagship into every batch.
The beers have been left to ferment for five days earlier than I returned so as to add the dry hop additions. Per the advice of Haas, I went with 70% the quantity of LUPOMAX as T-90 pellets.
Hydrometer measurements taken 4 days later confirmed a slight distinction in FG.
Left: T-90 1.006 FG | Proper: LUPOMAX 1.005 FG
At this level, I proceeded to strain switch the beers to CO2 purged kegs.
The crammed kegs have been positioned in my keezer and burst carbonated in a single day earlier than I diminished the gasoline to serving strain. After 2 weeks of conditioning, they have been carbonated and prepared for analysis.
Left: T-90 | Proper: LUPOMAX
| RESULTS |
A complete of 24 folks of various ranges of expertise participated on this xBmt. Every participant was served 2 samples of the beer dry hopped with T-90 pellets and 1 pattern of the beer dry hopped with LUPOMAX in several coloured opaque cups then requested to establish the distinctive pattern. Whereas 13 tasters (p<0.05) would have needed to precisely establish the distinctive pattern so as to attain statistical significance, solely 4 did (p=0.98), indicating individuals on this xBmt have been unable to reliably distinguish an American IPA dry hopped with T-90 pellets from one dry hopped with 30% fewer LUPOMAX pellets.
My Impressions: Out of the 5 semi-blind triangle exams I tried, I accurately recognized the odd-beer-out 2 occasions. Regardless of understanding the variable, these beers tasted precisely the identical to me, possessing the watermelon and low pear notes I anticipate from El Dorado.
| DISCUSSION |
It’s effectively established that dry hopping imparts beer with fascinating hop character, which is all however mandatory for contemporary IPA. Whereas bigger doses are related to elevated depth, brewers run the danger of extracting disagreeable off-flavors as a result of increased quantity of vegetal matter being added to the beer. To fight this, Haas created LUPOMAX, a product the appears to be like just like T-90 however has a better focus of lupulin with 30% much less plant materials. Tasters on this xBmt have been unable to reliably distinguish an American IPA dry hopped with T-90 pellets from one dry hopped with 30% fewer LUPOMAX pellets.
Contemplating the utilization charges, these findings aren’t terribly stunning, as they help Haas suggestion to make use of 70% the quantity of LUPOMAX as one would T-90 pellets. Nevertheless, the obvious lack of a sensorial distinction would additionally appear to point that neither beer had perceptible vegetal off-flavors, regardless of the T-90 batch being dry hopped with 30% extra hops by weight.
As a homebrewer, I’m not significantly involved about general yield, in order that doesn’t actually play into my choice for LUPOMAX hops. Quite, I’m a fan of Haas’ declare of consistency over time, because it means I’m extra possible capable of reproduce recipes with confidence. Whereas I’ve no downside with T-90 pellets, I can perceive why bigger brewers would discover them helpful, and I’ll undoubtedly be retaining them stocked in my brewery.
