Austin Homebrew Supply Greenbelt v. WLP001 - The experiment begins...

WLP001 on the left from a batch awhile ago - Greenbelt from this batch on the right - same gravities, same process

Cool experiment. Thanks for adding the photo. Wish I would have got in on the testing panel.

Testing panel has not yet been assembled, I haven't bottled yet - you're in Utah, shipping would be cheaper there. You may be on the list

 

[Drinks3point2]

Killer. I'll stay tuned!

 

[WrongCoastBrewery]

Holy cow! Thats alot. I am brewing with this next batch.

 

[bsdx]

Sorry if it was mentioned somewhere but I am having a hard time finding it, does Greenbelt have a strain number from Wyeast? What is it? Thanks.

Forrest - so far both my initial impressions and someone else in this thread have reported the same thing - a smoother bitterness....

Is that what your testers found?

I'm bottling both batches tomorrow!

 

[bsdx]

I knew where to buy it and get information on it, I was just looking for the strain number. Does it have one?

 

[Austinhomebrew]

Sorry no strain number. I guess we should have assigned it one. We were only required to come up with a name.

And a damn fine and well inspired name...

Thanks. I'm working on a list of yeasts and trying to gather the basics for as many as I can think of. Guess this makes it unique for now!

As soon as I saw that yeast I knew I wanted to make an APA or IPA with it. The only problem was I was leary about liquid yeast being shipped long distances, with temperature fluctuations and such. Guess I'll just order some and see how it turns out.

I'll also probably use this yeast to try out pitching directly onto a yeast cake. Maybe I'll make my first recipe a 1.050 APA and make my second a 1.090 IIPA and see how that goes.

shipping worries? good reason to make a starter. Fill'er up with good, new yeasties

Any updates?

Update....

Had some blind tastings tonight with me and my brother....

Here's the samples.

We both agreed that the greenbelt had more "bitterness" than the WLP001 sample. The WLP001 sample has a little more "complexity" - don't really know how to describe it....

Greenbelt seems to be a little "cleaner" - meaning, more crisp.

The aroma seemed similar between the two.

Overall - I was surprised how "different" the two beers were, considering they were derived from the same wort and what I thought would be similar yeasts.

WLP001 = more mouthfeel, less bitterness (relative)
Greenbelt = crisper/dryer, more bitterness (relative)

Either way - both beers were great, and I look forward to making an IPA out of greenbelt since it seems to enhance bitterness and make for a perceived crispness.

Those beers look nice, I could not get my Amber with Greenbelt to drop clear, even after a week long cold crash + gelatin. Did you filter or just give it time?

Just time...

26 day primary; 7 day secondary (dry-hop); 25 days in the bottle...

 

[bob1852]

I did some more blind tastings with friends over New Years - and the results were the same.....which I find interesting....

Also left a bottle of each with Soperbrew on HBT, so I hope he weighs in here eventually...

I just kegged up a batch last night with which I used Greenbelt. I had similar results in the amount of yeast at the bottom of the fermenter. It was unbelievable! I have never had so large a kreusen or so active a fermentation! only time I've ever needed a blow off tube, when using buckets. I washed this yeast.

I haven't really tasted it but I brewed Denny's Rye P. A. with it. I know its not on the recommended list, but it was what I had. From the reviews it sounds like this should be a good yeast for IPA's.

 

[Saccharomyces]

My impressions with this yeast ... Has spicy, earthy esters, especially in the aroma. Pretty clean ester flavor, slightly more esters than WLP001. Mutes the hop flavor slightly, but leaves a crisper, lingering hop bitterness on the back end. Definitely more flocculant than WLP001 -- when I use Cali ale I usually end up filtering, definitely not necessary with this yeast. When the beer is young, it will have an oniony flavor (seems to be the esters), but that seems to age out quickly. Accentuates the "cat piss" flavor and aroma of some American "C" hops.

Overall, it is most similar to Wyeast 1272. I still prefer Wyeast 1272, American Ale II, over this yeast for the beers I have sampled made with it (APA, Lake Walk), but I think it would be an excellent choice for a hoppy American IPA. I will give it another shot next time I brew up one of my IPAs.

In addition to American IPA, I think the ester profile and attenuation of this yeast would be ideally suited to an American Stout or Robust Porter style beer. The alcohol tolerance is listed at 10%, pretty low, so I would avoid using it on any of the imperials. In practice the alcohol tolerance of WLP001 is much greater at about 16%.

Not having much luck with this yeast. Made a nice big starter(750ml) as per usual, used yeast nutrient in the boil.

Over 24 hours to get going, which is slow by my standards. Last 3 batches on my new setup all were ripping after 12, and completely done within 4 days. On day 5, it's still at .024, crap. Krausen is almost dropped, but still a thick skin on top. I don't get it.

Wow. Total opposite for me. Stuff went crazy for me.... more than any other i've used.

That's what I was expecting, I swear it left a heap of yeast in my starter, more than i've ever seen. Very disappointing thus far.

 

[Old_E]

Really weird.

Any more impressions of the Greenbelt strain?

Any more impressions of the Greenbelt strain?

I have two IPAs entered into a state BCJP comp this weekend - 10 gallon batch, split into two fermenters: one with greenbelt, one with WLP001.

I'll post the judges tasting notes...

 

[mpruett]

Well, I know what I'm brewing next- an IPA using Greenbelt. My father-in-law's lived in Austin for going on 45-50 years now, he's a huge IPA fan, and their house is like a quarter-mile from the Barton Skyway greenbelt entrance.

 

[KoedBrew]

AZ what did the judges say?

 

[NuclearRich]

The people need to know, AZ!
