5 Yeast Experiment
|
|
So today I brewed up a light and boring beer so that I could see the effects that different yeasts have on beer. I bought 5 different dry yeasts then brewed up this beer...
7 lbs - 2-row
2 lbs - flaked rice
1 lb - flaked corn
0.25 oz Cascade at 60 min
0.25 oz Cascade at 30 min
Once everything was done I oxygenated the wort in one bucket then transfered into 5 one gallon bottles. Pitched the yeast and now all I have to do is wait. Here are some pictures for ya, the beers look different colors but thats only because some had been sitting for longer than others. I shook the wort after pitching the yeast so some have less cold break floating around due to sitting longer. After a few minutes they all looked the same.

Thank you sir! Seriously. Because of people like you people like me are able to get great information without having to do these experiments. Let us know how they turn out.

Awesome! I'm going the same thing now with 3 batches... brewed a ESB and used:
- S-04
- Ringwood
- 1968ESB
Looking forward to your impressions on each yeast, I'll post mine as well.

I just want to say thanks as well for this experiment. There are so many variables in a batch that its very hard to isolate one variable (yeast or water or temps etc) as the cause of a certain flavor. This seems like an awesome way to figure out if s-04 is really "fruitier" than us-05, and if Notty is really the most "neutral," for example. Also, I am very interested in seeing how the wb-06 turns out. Would have loved to seen the t-58 in there too.

Well here is what I found this morning, its been 17 hours since I pitched the yeasts. The Windsor actually foamed up so much that it knocked the foil off the top. I'm not too worried about infection right now though, when I took the picture there was still alot of CO2 coming out of the jug. Since the pictures I've cleaned the outside of the bottles with star san and I've replaced the foil with sanitized foil.

I've been planning on the same thing.
Got a load of 1 imp. gal. jugs (they must be older than 1976, since Canada went metric after that) free off of Craigslist.
Thinking of brewing 4.0 gals. of a simple English bitter:
6.5 lbs. English pale ale malt
0.2 lbs. Crystal 60
0.2 lbs. Crystal 120
1 oz. EGK (60 mins)
1 oz. EGK (10 mins)
Then adding four different yeasts to four jugs with :
Wyeast 1187, 1275, 1099, 1968
I have used 1318 for many English beers and love it, but would like to see whether I can find one that I like more. Figure that I can get 6 pint bottles out of each gal and have some buddies over for sampling.
I'll post my very subjective results when I'm done.

Ha ha, yeah I was lucky enough to get the bottles for free without having to suffer through drinking 4 gallons of the stuff.

good experiment. With limited brewing time it's hard to dedicate a brew day to experiments. I want to use every brew day to it's fullest to get good beer. Maybe when a pipeline is established I can do this. Or 10G batches with 5 safe and 5 different yeasts for experiments. Thanks for doing this. It's good to see data but it won't be comparable to you actually getting to taste the differences
