    Cl/SO4 implications?

    'A malty beer benefits from a higher Cl:SO4 ratio whereas a hoppy beer is accentuated with a lower Cl:SO4 ratio' (forgive me who I stole this above from I lost the link). What is the benefit gained in flavour/bitterness terms from high Cl:SO4 for a malty beer and conversely what is the...

    deionised water?

    We have a scource of deionised water. If I were to brew a light pale ale (97% pale + 1.5% crystal and 1.5% melanoidin) with bittering aimed around 30-32 IBU without making salt adds to the water. What would my mash ph be in the range of? Would there be consequences for fermentation in...

    shelf life (Why do commercial products last so longer?)

    What is the mechanism by which beer ages (and hence has a shelf life) in beer? Why do commercial products last so long unopened compared to most microbrews? Is it oxidation at bottling? This is not a question about spoilage organisms/refermentation! Pasturisation kills that stuff off but he...

    relative abundance of sugars?

    Id be keen to see the composition of a wort (% of various sugars) pre ferment and post ferment and yeast strain used if anyone knows where to get one? What Im trying to understand is how my mashing programme translates into the fermentablity of the brew and thus the resultant balance. I am...

    yeast attenuation

    Hypothetically if a selected yeast with attenuation of say 70 % was put in to a solution containing only fermentable sugars only (glucose say). Would the yeast attenuate 100% and if not what would be limiting factors? For arguments sake say the fermentable sugars were extraced from malted...
