I'm new to this, so this may be a silly question...
I'm using a Woodforde's Norfolk Ale kit. The instructions say to
rehydrate the yeast in a little cooled boiled water before adding it
to the wort.
I did so, but there was no sign of life from the yeast when I added
it. What sat in the cup was just a pinky-grey liquid, with no signs of
bubbles or foam as I would have expected.
I've added it to the wort and am waiting with baited breath for
action. In the meantime - am I wrong to expect the yeast to 'wake up'
and foam in water only?
When you cooled it down, it was at what temp when you added yeast?
You should rehydrate in warm (think body temp) water. Too cold and it
won't reactivate; too hot and you kill it.
No, there's usually some activity in water alone, but much more in a
starter solution. At about 5-10 minutes after putting it in warm
water there should be a bumpy surface of yeast on the water, and a
little foam develops, in an hour or two this sinks to the bottom and
there is little activity (in plain water). Dry yeast will remain
active for a very long time in the packet, but poor storage
conditions, or a small hole in the foil can shorten the life.
Likewise, putting it in water that is too hot will kill it. Lukewarm
water is about right.
MHO better to start in a weak wort rather than water and start well
before pitching to give the yeast a head start.
The question is how long in the fermenter and is there any activity?
At 12 hours I'd worry about it; at 20 hours with little or no
activity, I'd go for some fresh yeast.
Any yeast (even baker's yeast) is better than weak or dead yeast.
Baker's yeast may be your last resort, but it will make beer.
I'm bound to be castigated for that statement, but I had to try it and
frankly couldn't really tell a difference from tried and true
Nottingham ale yeast in the finished product. The fermentation was
faster and it smelled more yeasty while fermenting.

Thanks for the info - I think I must have killed the yeast, as there's
no sign of life in the wort after 6 hours.
Can I just add the contents of a spare sachet to the wort now?
You can add dry yeast at any time (some recipes even call for a second
pitching a week into the fermentation). The question would be: do
you trust the yeast? If you believe it to be viable yeast you can
either rehydrate it or pitch it dry into the fermenter.
If you are working with a carboy, I'd pitch it then rock the carboy.
With a plastic bucket, scatter it over the whole surface and close the
lid and wait.
One assumes you read up on the craft and know enough to cool, aerate,
and thoroughly mix the wort before pitching the yeast . . . Wort that
isn't aerated or mixed well will be slow starting.

Yes, I read the books first and aerated the wort with a (sterilised)
whisk first. But I think I made a basic mistake and killed the
original yeast by not waiting lonmg enough for the rehydrating water
to cool.;
You live and learn, unlike the yeast....

Let's not be so sloppy with terms. About 68-70 degrees is right. My
"lukewarm" could be your "cold".
Read the info any yeast company gives out for free. Rehydrate dry
yeast in water - wort can damage cell walls in dry yeast. Then, if
you want to make a starter (not needed with dry yeast - there are
enough cells in the packet for even a 10 gallon batch), start in wort
of the same general kind (if not exactly the same wort) as the yeast
will be fermenting.
Nah - any homebrew that isn't spoiled is better than tossing 5 gallons
of spoiled wort.

Yep. I've had good beer that didn't start for over 24 hours. One or
two of those erupted like Vesuvius later. Many of them started slowly
and fermented slowly for longer than usual. The only thing that
matters is what it tastes like after it's finished, carbonated and
chilled.
OK "lukewarm" is barely warm to the touch or slightly above 98.6 F.
I'm not recommending fermenting wort at that temperature just getting
the yeast started. 105 is probably starting to kill off some yeasts
(some baker's yeast will tolerate 115)
When "starting" (as opposed to rehydrating) yeast, the idea is to get
the cell count up, get the dry yeast used to the new living conditions
and ready to go. The end objective is fast fermentation when pitched
to avoid a wild yeast or bacteria getting established. The ideal
starter (and conditions) is not the ideal brewing temperature.
Different goals.
best idea, probably kills more cells then it helps, but one can use a
little bit of sugar to speed it up (or rehydrate and then put in
starter wort - but that requires two boiled liquids and is more time
consuming and uses more energy). Just rehydrating will work - but I
want to see the bubbles and smell the yeast before committing it to
the wort.
I do what works for me - pitching rehydrated or dry yeast is always
slower fermenting than my starter. My goal: blow-off in less than 6
hours, bubbles in >Baker's yeast may be your last resort, but it will make beer.

when i use an original yeast
i tend to add it to low temperature water, with corn sugar.
sometimes i will add a B vitamin to it.
rare yet an idea to consider.
the urge to get a molten vat of broth and convert it into beer is slightly
overstated.
technology evades some.
a cool wort is good for you.
bacterial infection is becum a big thing
i use only high temp components in my beer.
you got a balloon
you got an unused condom (non lubricated)
then you have a stopper for accidental infection.
my yeast uis built the day before i make beer,
i happen to keep it beside my sour dough yeast.
things grow in the fridge
not neccesarily good for yeast.
that green thing on the second shelf should be caught, shot or trapped.
rip off your condom or balloon or whatever, and give your jug the fully
active yeast.
Don't forget to save some trub in a beer bottle for your next batch to brew
or a couple of bottles while your at it. Yea, I've had good beer that
hasn't started for over 24 hours too.

Or a few pounds in the fermenting bucket. :)
*There's* one way to get fermentation to start fast.
they pack it with nutrients aka sugar to get it hopping
things not to do
do not stick a yeast pack on the dash of your car in the blazing sun.
never buy
economy for fast sale yeast. and if it does not have an expiry date on the
pack it is already expired.
cooled boiled water, always sounds awesome.
try cold to fingers water.
hey dude if you can drink the cold water so can your yeast.

Pete,
Contrary to what some people say, all yeast should be "woken up" by putting
it in a starter batch 1-3 days before you actually brew, but again, it's a
matter of preference. Keep in mind too, depending on the strain of yeast it
can take 2-24 hours for it to do anything, you won't see instantaneous
action.
Some people like to make a starter from liquor & DME boiled for 20-30
minutes (don't forget to remove the pot from the heat before adding the DME
to prevent scorching) and cooled to pitching temp (each yeast is different
so pay attention to the package). Unless you have a thick check book, this
can get expensive since DME is rather pricy.
Others, like myself, prefer to keep in my tradition of all-graining by
brewing a mini batch of the beer I'm making and pitch it in there (flavor
continuity). Once you see your yeast starter bubbling, you know you have
potent yeast and you can start brewing the full batch.
To make my mini batch I mash 1 lb of base malt grain + a sprinkle of each
specialty grains/adjuncts in 1 1/2 US Quarts of liquor at 150-160F, sparge
with 3/4 QT 160F liquor, boil for 30 minutes or until the total volume is
under 1 QT, cool, pitch yeast and wait.
I once read the analogy of hiring people off the street to build your
house....or hiring a licensed contractor to build your house. Thats the
difference of sprinkling dry yeast into your wort vs. using a yeast starter
that has been bubbling a couple days before you pitch it.
Try it once, brew a 2 gallon batch, split it into 2 primary fermenters,
pitch some dry yeast in one and pitch your 2 day old yeast starter thats
bubbling like crazy and watch the difference. You'll be amazed.
You don't need a lot of extra equipment to do this, I recycled an empty US
Quart sized vinegar jar with the small mouth, purchased a small rubber
stopper that fit it and an airlock all for less than $2. Works great. Make
sure your starter wort is cooled before adding it to a glass jar or bad
things happen. Also make sure the starter jar is sanitized properly as well
and aerate, aerate, aerate!!! Another option is getting a canning jar, lid
& lock, drilling a hole in it to accomodate a grommet, pop your airlock in
there and go, go, go!!
There's always a good chance that the yeast included in most kits is dead,
splurge on a pack of Muntons or Safale (Not bad for dry yeast), or if you're
doing an English try Nottingham or Winsor. It never hurts to have an extra
pack of yeast on hand either in the event you get a stuck or slow
fermentation or the pack in the kit truly is dead.
Liquids are a whole other story, to me are very expensive but worth the
price since you can always recover them after primary and save them in their
original tube. There are so many out there and each one is specifically
tailored to a style or type of beer. Again, personal preference. I've
never had a bad batch of beer from dry yeast, but they can all taste the
same even with different ingredients, I have had batches that failed or flat
out did nothing with liquid yeast, I should have just tossed the $7 out the
car window as I was driving home. In my opinion, yeast is 75% of brewing,
24% is sanitation and that last 1% is ingredients.
Sorry this was so long, but I wanted to cover as much as possible to give
you some extra info rather than just throw random, garbled and fragmented
sentences at you.

alt.beer.home-brewing:
Contrary to what you say, there's no need to "wake up" dry yeast.
The ONLY reason to make a starter with liquid yeast (aside from seeing
if it's still good) is to allow it to multiply. Since there are about
9 billion cells in a packet of dry yeast, there's no need for that.
There *is* reason to hydrate it, though. Wort tends to puncture cell
walls if they're dry.
For 4 ounces? If you can't afford that (about 75 cents), stick to
drinking water. Or, at least, to using dry yeast - or learning to
freeze your yeast.
Whoa, easy there killjoy, we're all supposed to be helping each other out
here. I didn't exactly see you offer up any constructive help. It's pant
loads like you that make me give up hope on the human race.
Notice the quotes...I was quoting his words, I know why starters are done.
I do drink water, but it's usually got a little beer in it. And since my
local brew shop doesn't sell dime bags of DME, it does tend to get
expensive. Besides, why would I wanna drink from a baby bottle when I can
drink from the fire hose like a big boy. And...didn't i mention something
about recovering my own yeast...oh yah I did. Now do us all a favor get
over yourself and learn some social skills and tact.
