Mixing yeasts

Post by Jaoqua » Sat Sep 13, 2008 10:09 am

Is it OK to add two different kinds of yeast to a fermentation at the same time? For example, using the kit yeast and also a separately-bought yeast? Sort of a belt-and-braces approach.

I'm about to start a Cooper's IPA but after reading a few posts I'm reluctant to depend on a kit yeast. If my local HBS sold S04 I'd just use that, but all it sells is Young's, and I've never heard anyone comment on that.

BTW I will be away from home till Thursday, which is why I'm considering adding them both at the same time, rather than just giving the kit yeast till Monday to do its stuff.

The standard kit yeast will be fine but using just i.e s04 is better, especially if your intending on bottling it. S04 sticks to the bottom of the bottle pretty well so it's easier to keep your beer clear when pouring whereas the kit yeast tends to float about in the beer if you so much as look at it.

You also have flavour additions to consider. Every yeast adds a subtle flavour characteristic to your beer, s04 being a fruity traditional ale type.

Mixing the yeast won't cause any untoward problems but I used to keep the kit yeast in fridge and use just s04 for those occasions when I ran out or fancied making a daft TC or something.

BTW, the coopers yeast are pretty good anyway so using s04 may be overkill.

Just use the yeast you have and give it ten days in the fv before transfering it to bottles/barrel. :wink:
