Dead Yeast?
|
|
I was planning on brewing today but it looks like that wont be the case anymore. I made a starter with a Wyeast Weihenstephan Weizen 3068 smack pack yesterday morning. I used 1 quart of whater and 1/2 cup of wheat DME. It's been pretty hot lately so it's pretty hard to get the temperature down, but I eventually managed to get wort down to 80 F and so I pitched the yeast into my starter (yeast was about 80 F as well). I didn't think this would cause any problems. However, there was no activity all day yesterday and there has not been any activity as of today either. The temperatures of the starter have run between 75- 85 F. Does it sound like I did something completely wrong?

That temp should be OK. Did the smack pack swell up after you activated it?

Remember yeast can take up to 72 hours to take off....long lag times happen, to no ill effect. And don't forget airlock activity also isn't an accurate gauge of fermentation....If you are in a bucket and going by that then that's not a good gauge...It's different obviously if you are in a carboy, because you can see the krauzen starting to grow...
There's too many factors that can make a cheap a$$ piece of plastic not burble...

If you are in a bucket though, if you press down on the lid and get a big "burble" in the airlock, then you have co2 and therefore fermentation is happenning.

Yes it did. I burst the inner pouch on late Friday and by early Sunday it looked like it was about to explode. I did notice right now that the airlock is bubbling every 15 to 20 seconds, but I'm not sure if it's because I mixed the wort/yeast inside after moving the starter a little. Do I just have to have patience? I really thought that the starter would go off very quickly and I would see a noticeable thick layer of krausen. However, I will be posponing my brewing day untill I see the starter do it's thing, if it ever does... I don't want to pitch it in my 5 gallon brew if I'm not sure the Yeast is viable.

Rarely do I see any krausen on a starter- but usually about 24 hours later or so, I notice a nice think layer of yeast on the bottom so it's done its job. Give it a swirl to keep the yeast in suspension, and it'll be fine. Just go ahead and pitch it in when your wort is ready- it'll go!

I used to use plastic buckets, but now I use better bottles. However, right now I'm just dealing with a 1 qt. starter. I see no Krausen, and I'm barely seen some bubbling, but I'm no yet sure if that is do to me shaking it a little while ago.

If you got regular bubbling in the airlock, it's venting CO2, if you made the starter yesterday. Some starters don't even krauzen, or they krauzen quickly then fall....Starters do the same funky a$$ crap as beers in fermenters, act unpredictably.
I've had some on stirplates that didn't take off until I shut the plate off....

O ok. This is the first time I've ever used liquid yeast and done a starter so it's a bit confusing. It's hard to tell when it's ready. Haven't seen much bubbling or much of anything at all, but I will try and trust that it will work. Just don't want to ruin a perfectly good batch of brew.
