Yeast starter in the fridge for >1 week

[Rob2010SS]

How long can you leave a yeast starter in the fridge before you need to re-do or feed it again?

I had a planned brew day on Feb 2nd in which I started a 2L starter on Jan 31st. My brew day got cancelled so I put the starter in the fridge on Feb 2nd. I'm wanting to use the starter this Thursday, Feb 13th.

The yeast is REALLY settled out and it'd be nice to decant this off, let the yeast warm up a bit and use it. My question is has it been in the fridge too long? Do I need to feed it again before using it?

The yeast is WLP066 London Fog.

Thanks in advance.

As long as it's been sitting under the starter wort it will be fine for many weeks. It should take off with no problems.

Second that. I made a starter for my last lager and life interfered with brew day. Ended up waiting 3 weeks, but it started right up. It makes sense if you think about the liquid yeast packs we get being much older and with lower cell counts.

I harvested good clean yeast from my unitank and let it sit for a full 1.5 months. Just added it direct out of the fridge this past sunday and by tuesday it was blowing out. Same yeast, London fog.
