Lager yeast - one pack for 8 gallons?

[Chappie519]

Hi,

Halfway through brewing a lager (8 gallons) and realised that i have 2 packs of yeast but there different types (saflager and youngs).

Is it alright to use 1 pack if i make a starter, or pitch two packs, or pitch 2 packs with a starter?

Cheers

is the US or imperial

and whats the O.G of the wort

I have heard lager need more yeast pitched compared to ales, due to the low temps of the fermentation conditions

oG near 1040. Imperial.

Think i might try to mix the yeasts in a starter!?!?

If you pitch warm then chill to fermentation temp then one 11g pack will do 5 gallons. If you pitch cold (at or below fermentation temp) then you'll need two packs but the flavour will prolly be better.

Does anyone think the two diff yeast will have much effect on flavour?

Depends on the yeasts and how different they are.

Is Youngs a real Lager Yeast? Or is it (as I personally suspect, but don't know) a Bottom fermenting ale yeast (ala a steam beer yeast)?

I know the S23 is a real lager yeast, I would probably go with pitching a Daab Flying starter into the wort at 18C before cooling down to the proper fermentation temperature. You won't be totally clean, but it will still be a good beer
