Duff yeast?

Postby blinky » Sat Sep 17, 2016 08:28

I have only used liquid yeast once before, the same as this time it was heferviezen WLP300, I don't make a starter as its only going into about 15l of wort. Pitched last night around half past midnight but this morning there is no sign of anything at all. The top of the beer in the FV Has no bubbles or any sign of yeast activity. Normally I would not be too worried but the packs use by date was mid October, the last pack I used was really fresh. Should I be concerned? It does say the lag is between 5-15 hours, I suppose it's only been about 8!
If the yeast does not start doing its thang, should I expect to get another fresher packet for free from the brew shop?

You should see bubbles on the side of the fermenter before you see anything up top. Check the fermentation temp and gravity if you see no activity by about 12 hours.

The first thing to change is the pH, but you need an accurate meter to detect that. When wlp300 takes off, you will definitely see plenty of krausen.

What temperature were the yeast and wort at when pitched?

I wouldn't worry just yet. Give it a few more hours.

Just back from the football (lost 2-1) but at least the yeast has woken up!

You had my interest tweaked there. I thought you were actually talking about the yeast used to make Homers favourite beer, Duffy beer :doh:

Ha ha! Unfortunately not, although I did have a duff beer when in universal studios last year at Mo's tavern!
Anyway, today I had to change the airlock as the yeast was trying to escape the vessel, definitely nowt wrong with this yeast
