    Mead - pH & acidity

    Thanks Mark, The comment re raising pH with acid was tongue in cheek.;) My confusion is why add base and acid. If I can’t get both pH and acidity in the ideal spot, which is more important? Best, dam

    Mead - pH & acidity

    Hi, I've been reading about the importance of pH and acidity when making mead... and, I'm a bit confused. Some say to add acid to get around 0.65% acidity (blend of citric, malic and tartaric acids). Others say to add a buffer such as potassium carbonate to raise the pH to keep it between...

    Herms Recirculation Rate And Recirculation During Sparge

    Hi Ross, Thanks for your comment, you may be right... Here's my thinking. Keep the recirc flow at around 3 L/m but tap off about 1.5 L/m to the boiler. This way the sparge water would be at least partially recirculated and the idea is that by having longer contact with the mash that the sparge...

    Herms Recirculation Rate And Recirculation During Sparge

    Hi all, I assume most HERMS units use the March pump, rated at 21 L/min. From what I read most HERMS users talk about recirculation rates of 2-3 L/m. 1) Is 2-3 L/m recirculation rate about right? 2) If so, is this done by throttling the pump inlet or outlet? Last, is there any benefit to...

    150 L Gas Fired Boiler

    Hi All, I have found some 150L SS tanks which I'm considering using for a boiler. The tanks are new and are approx 1m high and 45cm in dia and have a wall thickness of ~1.2mm (my guess) for $290. Due to electricity constraints, I need to gas fire most/all of my equipment (HLT, HERMS, boilers)...
