Guiness Irish Wheat Clone

Recommended Posts

Since I liked this so much I am trying to make something like it.

They use the Guinness Stout yeast, The wheat beer is sweetish consistent with low attenuation Ale yeast.

I am saving yeast from a 6 pack - 2 more bottles to go, plan to brew tomorrow or Wednesday.

From Guinness website they use Mt. Hood and Amarillo hops, have 21 IBUs and 5.3 ABV. So not much IBUs to add and some citrous flavouring adds.

 

I also found this page . https://edelstoffquest.wordpress.com/2014/05/23/brewing-better-wheat-beers-with-herrmann/

Their most interesting comment since there is no way I can get their mash temp profile EVEN if I was using AG was

In his paper,  Markus Herrmann (TU-Munich, Weihenstephan) describes a mash schedule better suited for wheat beers to enhance the formation of Ethyl Acetate and Isoamyl Acetate.  These esters are mainly responsible for what is known as the “banana aroma” in Wheat Beers.  Formation of these esters requires Glucose.  During a regular mash only 10% of Glucose and 90% Maltose are formed.  The “Herrmann Verfahren” enhances the production of Glucose via Maltase, which is most active at 38C and denatures above 62C.

 

So adding more glucose will hjelp ester formation. I do not know how much glucose is in the BW extract but I would think not as mush as they make.

 

 

Plan is to use Bavarian Wheat HME

4oz Wheat DME

4 oz glucose

PM of Maris Otter, Flakes wheat, Wheat malt (figuring which kind) 4 oz each

Mt Hood  hop boil in grain water for 3-5 min to add 2-4 IBUs

Amarillo hop add 0.5 oz at flameout and leave in.

Try to under pitch with saved yeast to encourage esters (probably yeast from bottles will not be overpitching I expect it will be under.)

ferment at ~ close to 70 deg.

 

Any suggestions welcome.

I would just note that most wheat beers are actually pretty dry, in terms of FG, but the low IBU creates the perception of sweetness. I love Amarillo hops with a wheat beer, I think this'll come out quite well, regardless of how close you get to the original.

Forgot to mention! So will raising your fermenting temp a bit higher than normal. This approach, in my opinion, is better because there's less risk of off-flavors.

That's another very common method, might be challenging in such a small batch

 Tim, thanks for comments.

Well I will have to try those, for one - I could not find any glucose. None on Beer supply store and CVS drug store only had flavored, and none in health store. SO....

I will increase the Wheat DME to compensate.

For under pitching - I will just use what I get from the 6 bottles and hope. I bought a backup pack of WB-06 in case it does not take off. I have seen some slurry cell estimation methods but I think they had more than I do.

For sweetness, I was looking at yeast attenuation. Stout ale yeast --> 73%maybe and drier yeasts WB-06 -->  86% - drier than lagers.  Actually WB-06 seems to be pretty unique in that most other wheat yeasts are quoted in low 70's% atten.  by Beer Recipe Calculator.

I have the 6 bottle dregs now and I put a carbo drop in and about 1.5 cups water - and left it at ~ 70 deg. Lets see what it does overnight.

Ah, I managed to miss the part where you weren't using the yeast that came with the refill. That's a much lower attenuator. I obviously need to stop reading so fast.

Yeah, this is the Guinness Stout Ale yeast (they say) .

What is the refill yeast attenuation?

 

Limited info in the videos on the Guinness beer web page.

Very cool experiment! I'm totally surprised that you had trub in your Guiness Wheat beer. I've never seen that in a commercial brew.

 

Also learning a bit in this thread about dryness and sweetness, and yeast influence on it.

Bottle conditioned beer I feel is a huge thing right now. I think when you’re drinking a commercial beer you just aren’t looking for sediment but its there in a lot of beers. Some home brews just have more than commercial beers.

Mine sure do have sediment even with cold crashing. I'll be interested to see if my new little fermenter with the rotating racking arm will make a difference. The fermenter has a conical bottom to catch the trub, so maybe it will help cut down some sediment at bottling.

The Guinness Wheat beer bottles have sediment. Lots of sediment.

The question is - is it alive - or just for show? 

We will find out 🤓 did not see much happening yet though.

It sure smells yeasty though.

 

I have now 2 carbo drops in there  to try and get it interested in my mason jar.

Some have original fermentation yeast in there but some use a different yeast for bottle conditioning (and to stop people propagating proprietary yeasts)  so you cannot always be sure what you get. Several Belgian beers and most European wheat beers have sediment.

Well, I made the wort --> LBK this morning, pitched the pot of saved Guinness bottle trub yeast when it cooled a few hours later.

 

I hopeful but I am not too optimistic as I did not see any action from the yeast in the saving jar. But looking carefully with a MAGNIFYING glass and flashlight I do see some VERY small bubbles at the side of the LBK/WORT meniscus.  So I will give it 24 hours in 70 deg, ambient, and then put wheat yeast in if nothing is happening.

 

I might also have put too much Mt Hood in when I boiled for 3 min. The LBK was giving off a real hoppy aroma before I closed it. So I guess there is a trade off in what you get by putting a lot of hops in for a short time  (0.5 oz for 3 min) or a small amount for a longer time (1/8 oz for 12 min.). The recipe builder may calculate the same bitterness but the flavor/aroma will be very different.  Another experiment with too many variables lol.

Well OK, I am impatient but still no signs of activity so I pitched the Mr B Wheat yeast that came with it (can dated best by 2020 so it should be good)

I am guessing they must have pasteurized the Wheat beer despite the sediment.

 

Note to Mr Beer...…… The Wheat yeast packets are still not labeled with a date code. Is the idea that they will always be good until the "best by " date on the can - so no need to date them?

If using after can best by date should yeast always be replaced as a guideline?

Ale yeast continues to be date stamped. (?) A different  supplier?

I don't know what led you to believe that the Guinness Irish Wheat isn't pasteurized, or that it's carbonated in the bottle.  Wheat beer with yeast in suspension is normal, but it doesn't tell you that it's alive.

I was just being an optimist...……. so I had to try. And it smelled like live bread yeast.

 

But I can always try Wyeast Irish Ale yeast next time.

The yeast may well have been alive.  The issue would be that it is in such small numbers that it would have to be built up in multiple starters to get an adequate cell count for pitching.  You stated that the "saving jar" had some bubbles.  Was that fresh wort that the yeast were put into or just the beer from the bottles?

If I read @Nickfixit's comments correctly he used carbonation drops for his starter wort. If they were DME drops the gravity and cell count may both have been too low. If those drops were sugar the yeast may have been too old to recognize it as an energy source for reproduction.

Thanks for the comments on yeast saving. I figured that any live yeast would grab onto any sugars if present. 

How would you go about resuscitating it if alive in small numbers? There was probably 1/16 inch sediment in the jar from the 6 bottles.

When bringing back yeast from bottles, the numbers are low and need to be built up to a level for proper pitching.

 

1st step is to make a small 1 cup starter of about 1.020 SG, add the bottle yeast and leave that go until you see visible activity and the yeast takes the gravity down.  This could take a day or several days.

2nd step is to make another starter about 2 cups in size and about 1.036 SG and add the yeast from the 1st starter to that.  Now you should have better numbers and in about 24 hours you should see that starter finish.

3rd step is to make another starter about 1qt in size and about 1.036 SG, add the yeast from the 2nd starter.  In about 24 hours you should have enough yeast to pitch a 2 to 2.5 gallon batch at 1.050 SG.

 

Yeast cell numbers will double about every 100 minutes but you are starting with only a few thousand cells.  You need about 100 Billion for a 2 gallon batch.

 

Note: Don't cold crash between starters, just pitch the entire amount into the next starter.  Your third starter will be nearly 2 qts in volume when done and that starter you should cold crash for 24 hours and pour the spent wort off of the top of the yeast.

Thanks, I have to try that.  I used carbo drops not DME too figuring it had a variety of fermentables in it.
