I am in the process of again harvesting some yeast from a bottle conditioned Ale and am unsure about the volume of actual yeast slurry I need for a 6 US gallon batch which will have an OG of only 1035. Have looked at Mr Malty and still unsure. Previously I have just pitched the 2 litre starter and it has been successful but I want to do it according to what is recommended rather than what appears to have been ok previously.
The calculator has 3 tabs labelled - Liquid Yeast , Dry Yeast and Repitched from Slurry
The yeast that I have grown (from one 375ml bottle of ale) in flasks via multiple step up stages still appears short of the figures the Mr Malty Calculator indicates as the recommended quantity.
Assuming I am going to have a 23 litre (6 gallons US) volume of wort at an SG of 1.035 and temperature of 22°C (71°F) and I have finished the step up of the starter 30 July 2011.
Can the calculator tell me an actual recommended volume of yeast (slurry only - not spent wort) from this cultivation method that I should pitch? Do I use the Repitched from Slurry tab for my calculation? I tried this tab and set the concentration slider to about 4 (nearly full right) and set the Non-Yeast % Slider to around 5%. This indicated the recommended yeast volume was 43ml. Am I on the right track?
Can anyone walk me through the process if I have it all wrong.
