I made a 1 litre starter with the pack of liquid yeast. I read about freezing yeast samples on another site. Basically I mix a small sample of my yeast with glycerol. It has to be around 12.5% glycerol and this prevents water ice crystals from damaging the yeast cells. I freeze 15ml sample tubes. Then I just defrost, add to another small starter ( 25g dried malt in 250ml) then add the yeast from that starter to another larger starter (eg 75g malt in 750ml). This second Saison I have started was the first time I have used the frozen yeast method. Saves quite a bit of cost on liquid yeast! And I still have 5 vials in the freezer.
