Think i might be drinking sediment ??

Not to try and hijack but I did try pitch some yeast at 16C in the hop the lower temp would prevent the ester production but it was infact worse. Is this because I stressed the yeast with the low temp?

Probably I think stress can cause ester and fusel production.

Or maybe you just don't like the yeasts - try a liquid one.. its a whole new world of flavours out there I find S-04 does a job and makes a nice beer, but the liquid ones are quite a dramatic improvement :thumb:

If i was you i'd get a fish tank thermometer with probe (around £4) and pop that into your fermenter , there really is a difference to inside and outside fv (even if submerged in a water bath) especially in the first few days (while the yeast goes crazy) this is your main time to monitor temp in fv . And as stated don't stress the yeast such as get it to room temp before pitching and also get brew to around 20/18c first . And finally if your brewing 50L i would use 3 packets of dried yeast (or a large liquid starter) as with hefe brewing starting with low yeast helps stress the yeast which gives more esters so using more yeast should help .

I like a bear which is complex,

I like a bear as much as the next man but easy maintenance ones are so much easier to take out!

Would that be a bi-polar bear?

:clap:

Forgot about that point as well :thumb:

The larger the volume of starter the less growth phase which equals less ester (and fusels for that matter)

Please tell me you did that deliberately? :rofl:

guess i am fubered then.... i though i had got the difficult part done with the first AG brew under my belt...now the yeast is going to get me...maybe i was putting to much yeast in, given i chucked in an 11g packet of saf04 into 15lt of wort..and then the growth phase caused all the esters.....would it be better rehydrate the yeast an hour prior to pitching and make a starter of it before pitching ?...the main growth phase being done in the starter, or am i getting this all wrong ?

You should rehydrate to ensure the yeast is as viable as possible :thumb: This will also help you. No need for a starter with dried yeast ( you don't actually want one ), just rehydrate according to instructions. :thumb:

That is what I thought :thumb:

I have got some US-05 and Nottingham to try next and see. Whould love to use liquid but I want to wait till have have the space to split the vials and use 1 vail for 4-6 brews rather than just the one. Its cause I am a cheap skate!!!

Good advice Pittsy. This seems the most logical way to moneter the temp. I will give it a go :thumb:

Sorry Alistair, no offence meant...

 

[graysalchemy]

I'm not

Sorry to offend anyone who is.

But I do struggle with terrible spelling and also not reading things through, always have and always will be.

But does it make me a bad person ? probably not. :lol: :lol:

No it doesn't.

I'm sure it's something else entirely that does...

I bought one from ebay. 25W should be fine for a standard 5 gal brewlength. Much more, or if your brewing space is particularly cold you'll need a higher wattage. Cost £3.88 with free postage. It comes from Hong Kong though so it can take up to a month. I've not had chance to try it in a brewing environment, but I gave it a test in 5 gal of water. It's fully submerisble and the thermostat works perfectly.
The only problem is there is no transformer attached, which means you are running 230V of electrical equipment straight from the mains and into water, which is obviously not a great idea. Had i realised this i would have paid a bit more for a safer one, but I'm tight and impatient :)

S-05 is probably my favourite dried yeast and I still use if for some hoppy pales, if you are looking lower esters this is the one :thumb:

Also, if you try a good top cropper like WLP023 then no need to split, I use a starter to pitch to 50l then crop it after about 3 days ( if you don't then there's a good chance you'll have yeast everywhere, it is especially lively ). I then keep this in the fridge and if not using for a couple of weeks I'll just make a new starter with it and go again :thumb:

Not sure how many generations it will remain stable for, but a break in brewing ( or forgetting to crop :whistle: ) has always meant I buy a new vial every few brews. Also keeps SWMBO happy as I only have one pot in the fridge not six

Great idea, I will keep this in mind if I dont have much success with us-05 :thumb:

You miss read my post i think , yes you are better at getting a heater ( i would advise 100w as 50w struggles and 25w may be too small , even though it states so many liters etc my 50 w struggles while my 100w does it with ease ) and it's also best to pop fv into a water container and heater in water not fv (so you can adjust , the thermometer on the heaters are crapola don't trust em) i was on about getting a little thermometer a digital 1 with a probe http://www.amazon.co.uk/WMA-Digital-Aqu ... ermometers and pop that into your fv and adjust heater as needed .
