Hey everyone, brewing a northern english brown this weekend with an estimated 5.25 gallons of 1.056. I grabbed the last packet of WY1028 London Ale yeast at my LHBS which has a MFG date of June 13th. I've looked at both Mr malty and brewers friend yeast pitch calculators and both estimate around 35% viability. With that said though mr malty says I need a 2L starter and brewers friend says I only need a 1.25L starter. Thoughts?
