“West Coast Pilsner is a refreshing, light-bodied beer fashion with a golden to pale straw shade. It’s sometimes brewed utilizing American hops, which give the beer a extra pronounced hop bitterness and a floral, citrusy aroma. The hop character in a West Coast Pilsner is often extra assertive than in a conventional German Pilsner. The beer has a crisp, clear style with a refined malt sweetness that balances out the bitterness from the hops. It has a dry end that leaves a refreshing aftertaste. The carbonation is often medium to excessive, which contributes to the beer’s general refreshing high quality. A West Coast Pilsner sometimes has an alcohol content material between 4.5% to six% ABV, which is barely increased than conventional Pilsners. It’s a nice beer to get pleasure from on a heat day or as a refreshing accompaniment to a meal.”
In accordance with the above description from ChatGPT, one would assume that West Coast Pilsner is a well-established fashion that’s documented and outlined within the BJCP tips. Properly, assume once more! Right here at The Brü Membership, we lean into new and thrilling brewing developments, so we determined to dive deep into the novel West Coast Pilsner.
The AvgBrü sequence is a quarterly undertaking the place membership members are given the chance to vote on a base fashion in addition to varied ingredient and course of parameters earlier than brewing the recipe on a collective stage. Within the first quarter of 2023, the membership chosen West Coast Pilsner because the fashion of selection, regardless of it not essentially being an actual fashion, not less than inasmuch because it’s not acknowledged by the BJCP… but. Having by no means brewed or consumed this “fashion” earlier than, I used to be excited to place it to the take a look at. Along with choosing the fashion tips, The Brü Membership additionally settled on two prompt lager yeast strains to select from, each from LalBrew– Diamond and NovaLager. Moderately than selecting only one, I made a decision to check these dry yeasts in a cut up batch of my AvgBrü West Coast Pilsner!

I began off by milling the grains I picked up from Gnome Brew, the 2022 Homebrew Store of the Yr, which I’m fortunate dwell near right here in Chicago.
Because the water was heating up, I adjusted it to my desired profile.
When the water was correctly heated, I integrated the grains then let the mash relaxation at 149°F/65°C.
When the 60-minute mash was full, I eliminated the spent grains, transferred the candy wort to a kettle, and boiled it for 60 minutes earlier than chilling the wort to 170°F/77°C, at which level I added the hop stand addition. After 10 minutes, I completed chilling the wort.
Whereas the wort was chilling, I started rehydrating the yeasts.
A hydrometer measurement of the chilled wort confirmed it was at my goal OG.
1.053 OG
The chilled wort was cut up evenly between two 3-gallon PET carboys that have been positioned in my chamber managed to 58°F/14°C, at which level the yeast slurries have been pitched. By the next day, each beers have been displaying indicators of exercise.
Left: Diamond | Proper: NovaLager
With exercise absent in each beers 6 days later, I took hydrometer measurements displaying they have been on the identical 1.009 FG, so I set the temperature of my chamber to 70°F/21°C then added the dry hops.
Left: Diamond 1.009 FG | Proper: NovaLager 1.009 FG
After 2 days, I cold-crashed the beers over 4 extra days earlier than transferring every to CO2 purged kegs, which have been positioned in my kegerator the place they have been left on gasoline to carbonate for per week earlier than they have been able to serve.
Left: Diamond | Proper: NovaLager
| RESULTS |
A complete of 20 individuals of various ranges of expertise participated on this xBmt. Every participant was served 2 samples of the beer fermented with Diamond and 1 pattern of the beer fermented with NovaLager in numerous coloured opaque cups then requested to determine the distinctive pattern. Whereas 11 tasters (p<0.05) would have needed to precisely determine the distinctive pattern with a purpose to attain statistical significance, 13 did (p=0.004), indicating contributors on this xBmt have been capable of reliably distinguish a West Coast Pilsner fermented with LalBrew Diamond from one fermented with LalBrew NovaLager.
The 13 contributors who made the correct choice on the triangle take a look at have been instructed to finish a short desire survey evaluating solely the beers that have been completely different. A complete of 4 tasters reported preferring the beer fermented with Diamond yeast, 8 stated they preferred the beer fermented with NovaLager extra, and 1 reported perceiving no distinction.
My Impressions: Out of the 5 semi-blind triangle assessments I tried, I accurately recognized the odd-beer-out all 5 instances, and in each occasion, I used to be in a position to take action on aroma alone. I perceived the beer fermented with Diamond yeast as having a definite grainy aroma that was absent within the NovaLager pattern. The beers have been much more related by way of taste, and whereas each have been good, I felt the hops have been barely extra highlighted within the batch fermented with NovaLager, which appeared extra stylistically acceptable.
| DISCUSSION |
If we’re to imagine generative AI like ChatGPT, then West Coast Pilsner is a method that’s shortly gaining reputation, unsurprisingly, on the west coast of the USA. In making this distinctive new fashion of beer, brewers have various ingredient choices to make, together with which yeast to make use of. A pair frequent dry lager yeast choices, each from LalBrew, are Diamond and NovaLager. The actual fact tasters on this xBmt have been capable of reliably distinguish a West Coast Pilsner fermented with both of yeast strains suggests every contributes distinctive traits to beer.
Whereas lager types are identified for his or her clear fermentation character, which is a operate of the yeast, there are a variety of strains that purportedly impart distinctive traits. This appears the more than likely clarification for these outcomes, as Diamond and NovaLager not solely have completely different sources, however the latter is famous to be a “true bottom-fermenting Saccharomyces pastorianus hybrid” that performs effectively at comparatively heat temperatures.
Going into this xBmt, I actually didn’t know what to anticipate. Whereas this was a brand new fashion for me to each brew and drink, I did have a preconceived notion that as a result of lager yeasts are usually anticipated to be cleaner, it could be very tough to inform the beers aside. I couldn’t have been confirmed extra incorrect! Going ahead, I will surely think about using NovaLager for lager types than lean towards hoppy, whereas Diamond appears to emphasise malt character. One factor is for certain– I completely liked the West Coast Pilsner I fermented with NovaLager, to the purpose it’s going to be a staple on draft at each my residence and workplace right here in Chicago!
