Old Kits

[Stomach]

I've inherited (some time ago now!!) some old kits:-

Brewferm Frambois
Coopers Mexican Cervza

Their expiry dates were 2017. I assume they are still 'usuable' being in tins but will obviously need new yeast.

I was wondering whats the best yeast for each kit.

Cheers in advance!

I assumed you are bottling.

Brewferm Frambois - Lalbrew London Yeast. A Nottingham yeast might lift up the fruity hoppyness a bit more?

Coopers Mexican Cervza. Drinking cold? An ale
yeast. Probably fermentis saf-04.

Keep in mind that the extract had probably darkened over the years.

I assume they are still 'usuable' being in tins but will obviously need new yeast.

Actually the yeast is probably still in reasonable nick - dry yeast goes off pretty slowly, it has a half-life of up to a decade.

Personally I'd be far more worried about 5-year-old liquid extract.

But to answer the question - the Brewferm kit is probably using Brewferm Blanche, but anything like Lallemand Wit will do.

For the Mexican lager, any dry lager yeast will do - 34/70, Diamond, Mangrove Jack M54 - but some of the Mexican breweries seem to use Urquell derivatives which would suggest S-23 is the most appropriate option, although it's not as clean as those first two.

I definitely wouldn't use S-04 for a lager.

To be honest Mexican Cervza use a blend of yeasts which both lager and ale yeasts.

I do a nice light "almost" lager with S-04. Different folks different strokes
