Yeast Amounts - Two Packets Or One?

[fuddnuddler]

Greetings,
Just wondering what effect is there in using two packets of Coopers yeast (7g) rather than one in a 20l brew I'm about to put down.
Will it impact on flavour in any way?
Cheers

The affects of over-pitching (too much yeast) aren't as bad as under-pitching but in this case it'll be marginal. For an average 20L batch about 10g is ideal, so a bit over isn't going to have any negative effect. Worth doing if you have two packets spare (especially if one is 12 months old), even better if you can keep the temp under 20c (which I know will be fun in Adelaide currently!).

gday
I know youve probably heard it already but it is better to reculture some yeast from a coopers long neck and ferment with that, its a very simple process and makes a lot nicer beer in many peoples opinions. Nowdays i only boil up the kit yeast as nutrient for the primary yeast. happy brewing :icon_cheers:

if i'm using kit yeast, i always use two packets into a 500ml or 1 litre starter.
(us05 or nottingham are my usual yeasts)

i can run the temp down at 16 degrees without ferment stalling and that definately reduces the funky 'green apple' type of thing.

go for it!
