Yeast for DIY CO2 System

[nagukush]

Friends, just wanted some guidance on the yeast to be used with the DIY System. Actually I can get 3 types of yeasts here-

1. The normal Brownish colored Speheres that come in boxes from common stores

2. A Baker here has these small white colored granules

3. A Yeast Paste that I recently got from another baker. He said that it works instantly. I've used this for my current DIY Co2 but it doesnt seem very efficient...

Which of the above is best suitable for our DIY System ? Kindly guide me...
Thanks a lot !

# 2 and sugar and warm water (if it is "ACTIVE" yeast).

Agreed I use #2. Most grocery stores sells the fleischmans dry active yeast in the bakers isle.

Thanks a lot for the kind replies, Friends :) So is the paste thing a waste ? Its not exactly a paste but was like soft cakes or chunks of White colored mass. The shopkeeper said that its to be stored in the refrigerator or else it will get spoilt.... Any ideas friends ?

They would all work. The only difference would be the time it takes the yeast to activate and ferment.

As long as the yeast is viable and has a proper food source -- sugar -- all would work. If you have access to a beer or wine brewing shop, the best yeast is a strain used to make champagne. It lasts 2 to 3 times longer than typical baker's yeast.
