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

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...

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...

Hi all, I'm considering an auto sparge water top-up for my next system. I find that I have often let the grain bed get exposed/run dry when sparging. I know better concentration would fix this but an automated alternative would be good... just in case ;) This is my current idea: The...

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...

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)...
