Yeast starter - eggy

[UKSkydiver]

Hey
I've built 2.2L starter from about 20ml of overbuild from 3 months ago.

Yeast is 37/40

It's been on the stir plate for about 40 hours and it's has a bit of an eggy smell.

I know this can happen during regular fermentation, but is this a concern when making a starter?

I'm letting it settle and will try the liquid later and see what it tastes like.

Cheers

Lager yeast is known for a sulphur smell. Can't see any difference between this smell coming from the starter or main fermentation so I would carry on.

Thanks Ben.

I managed to do some further research (I was unable to do so earlier) and it seems that sulphur smells are perfectly normal with starters, especially those using lager yeasts.

I have only done a couple of starters in the past so I wasn't sure if this was cause for concern. So I will throw this in tomorrow once the wort has cooled.

Thanks
