Not much action from WLP001

[CreweBrewer]

Pitched a healthy (good krausen) 700ml starter into my 1.046 OG Mosaic pale yesterday afternoon. Got home from work this morning expecting to find a nice dome to the lid of the FV, but nothing. I cracked the lid and there was just a few lumpy groups of yeast on the top. The temperature probably dropped to around 17deg in the room overnight. I gave it another good aerate and moved the FV into the living room in the hope that it'll kick off.

This lag is worse than US-05! I was expecting more, seeing as my WLP002 went of in about four hours...

Wlp001 will drop out pretty quickly if the temperature drops mate.

Gotcha thanks. I thought like US-05 it'd have temperature range of around 15-22deg.

Gotcha thanks. I thought like US-05 it'd have temperature range of around 15-22deg.

Sorry dude, I should have been a bit clearer. It's the fluctuating temperature that this strain doesn't like.
White Labs site says optimum temp is 20-23 for this strain, although I've fermented it at 18. I'd definitely think 17 was a bit low.

That's great, thanks mate. It's at 20.5deg at the minute. I've given it another good stir. It's my first time using this stain.

It should give you a furious fermentation at that temp, I did it at 20* and it got 1.048 down to 1.009 in five days. Nice clean and balanced finish.

 

[CreweBrewer]

It's definitely going now. Not sure about furious, but definitely working.

 

[CreweBrewer]

Well this did end up furious. So much in fact that it bubbled out of the FV. I'm worried now that I may have lost some of that Mosaic aroma and flavour. I took a gravity reading and took a sniff of it before dry-hopping and there much of a tropical whiff to it. It's been fermenting at around 18c - 21c.
