Got a question for you regarding 71B: do you / can you measure the titratable acidity of your ciders? If so, does the malate degradation of the 71B strain make a measureable difference?
I dont measure it (though I could... Might do so this year) but on side by side tastings, the 71b gives a smoother less acidic result (less perceptible anyway) than yeasts that dont degrade malic acid.
