Woodfordes Great Eastern Yeast problems

[delboy]

Ah disassociating within any issues that might arise in future, very cunning

It sounds like a good idea to be honest, i think that i will try it. On a similar vein, marmite is also yeast extract so might work well added to a darker beer like a porter......hmmm

Caught red handed

I don't see where it could go wrong though TBH.

marmite and beer that would be nice and salty, would certainly leave you wanting another

[jaytee1]

hmmm yes the salt from the marmite might not go down too well...

well ive just mixed up a starter with boiled yeast to see if works, and as it goes one with marmite and one with yeast nutrient just to see how they compare.....has a load of yeast left from a brew kegged this week so have hopefully put it too some good use......

[delboy]

nice wee expt , how are you going to tell how well each worked, are you going to let them ferment out completely and see where the final gravities got to?

If you are looking for a difference in the initial strength of the ferment i don't think you'll notice much difference, there will be plenty of nutrients at the start of the ferment its in the finishing straight when the goodies run out that you should start to see the diffs.

PS if adding small amounts of marmite ie a teaspoon/tablespoon to a 5 gallon batch i think salt levels would be a non-issue, if you are looking to make a marmite stout that might be a different matter

Well i have the expos in 3 PET bottles in and im interested in seeing how quickly they start as much as anything. Each PET has an airlock in the top so i plan to see just how quickly the bubbles
a: start
b: rise
and now that you mention it
c: how long they last for before the malt extract runs out....

as its the first time that ive reused yeast from a previous brew im also interested in seeing how to use it...

so should be a good experiment all round.
im sure though that when the missus sees the bottles she'll think that my madness has reached new depths


yeah my thoughts exactly about marmite and a dark beer...

[jaytee1]

After one day the experiment is as follows.

All three bottles are nicely active, however the bottle with the marmite does not have a yeast head at all. Both of the other bottles have a nice yeast head and very active. The one with the yeast boiled in 100ml of water though has the most promising activity.

I will def take final SG readings though.

[delboy]

sounds good, keep the regular updates coming

How much marmite did you put in the starter, i know marmite is v.low in fat but it does have some and fats are know to kill head formation, its probably fermenting normally though even if it doesn't look like it.

Again the amount you put into 5 gallons probably wouldn't hace this affect.

Yeah be sure and post the FG, oh and a blind taste test would be nice too

[jaytee1]

There will be more updates than sky news !!

One level teaspoon of marmite went in dissolved in 100ml of boiling water. It is bubbling away nicely aswell, though perhaps not as vigorous as the two others.

Blind taste test hey, ill have to get the the good lady to help with that and she will probably feed me tabasco sauce knowing her sense of humour!...

I'll keep you updated...

[jaytee1]

Another update dellboy

Well i think that some of the elements of the experiment went well.
The marmite starter got too 1016 fg and there was definately a taste of marmite in the finished liquid that wasnt too unpleasant but def wouldnt be wanted in a light ale, the jury is def out on whether it would be pleasant in a dark ale too......

The starter with boiled yeast also performed well and got down to 1016.

The starter with yeast nutrient, tasted foul and i think must have had a baterial infection at some stage. It was really nasty. The FG was 1024..

I think that I may invest in some apperatus and try this experiment again as i am not sure of the accuracy of some of the stages. I had difficulties making the fg readings as i didnt have beaker thin enough for the hydrometer so cant rely totally on the final g readings.

Ill keep you informed if I attempt this again.

Missed this update, thanks for posting it
Kind of weird that the one with yeast vit should do so badly and smell so foul (must have got infected right enough)

Let me know if you decide to try it again.
Not sure if you did it this way the last time but i would definetely suggest that you treat the wort the same ie pitch yeast, aerate, split into three and then add the yeast-vit etc.

That way they have exactly the same amount of yeast and aeration.

[jaytee1]

yeah i didnt do that, def a good idea for next time.

I will do this experiement again but much more accurately so will keep you posted.
