What yeast is it?

[Robsparky99]

Popped into my local wilkos and snapped up a Cervaza and sweet newbie brown kit as they were cheap. Got home and decided I would be a nice brewer and open all the kits I had and put the yeasts in the fridge.

Opened the wilkos, muntons larger, brewbuddy larger and brew maker pilsner kits and they all had the same silver yeast packet inside.

Does this means it's all generic ale yeast?

They were obviously made by the same factory and it is possible. Turn them over and there should be a code, which included a use-by or manufacturing date, and often type and batch.

Ok... so I have the following codes:

OJB
NPB
LQB
MJB
JTB

No dates and no other than the standard writing on the front of the packets

I had a load of these in the fridge as I use Wilko Gervin yeast with their kits. I can't tell you what it is but it does make great bread.

In that case I would say yes, just generic ale yeast. Coopers here revolutionised the kit industry with a "generic ale yeast," but it was one that would ferment clean at a wide range of temperatures, flocculates well and has medium-low attenuation. I'd keep them for ginger beer, sourdough starters, etc. and learn to propagate your favourite yeast.

I seem to remember reading somewhere that the Wilko Gervin ale yeast is Danstar Nottingham.

A lot of the Coopers kit yeasts come in identical packets, but different codes mean different yeast. For these though, I suspect they are all Nottingham as it is dirt cheap and would work well with all the styles mentioned.

My guess is that these are Batch codes, as the BBE date is on the can.

Muntons provide Standard and Premium Gold yeasts with beer kits, but I rarely used them when I was making kits. I used Coopers or Safale US 05 as these ferment at the 20-22C that my brewing cupboard is usually at.

The letters on the reverse of a Coopers yeast identifies whether it is Ale, Lager or a mixture. The five digit number tells when the yeast was packaged dddyy
