I use a counterflow chiller in my operation but I had this idea for a more efficient 'self flowing' (on the wort side) immersion chiller. Instead of a simple helix, it's a helical formed into a cone shape, pointy end up. This shape should present coil surface area in a parallel wort flow pattern...

I've been researching the limitations of yeast starters. In particular, why a starter, innoculated with a given amount of yeast cells, has an upper limit to it's size. Thus, the whole step-up thang. So, it appears that yeast health suffers when you pitch a small innoculation into a large...

I did pretty well in chemistry (no organic, though). I've been brewing in my current location for about 8 years now. With pretty good success. My municipal water report indicates 80 mg/L of Ca and 127 mg/L alkalinity. So, the alkalinity number explains why I have to acidify nearly every brew...

Anyone know why Polyclar Brewbrite is not available from internet brew stores here in the U.S.? I've noted several folks using it that say it's something to get your hands on--most overseas. It's available in 90 and 100 gram increments from brew stores in Aus and UK. But not in any U.S. brew...

If you've ever made a slotted lauter tun manifold then you probably know of several ways to cut the slots. Anyone ever run across a tool to deburr the inside of those slots? I'm building a manifold with curved sections of tubing and its not obvious to me how I'm going to inside deburr. Because...

Anyone ever see the gooseneck fittings on the lauter tun outlets of a professional brewers (old world?) lauter tun? I'm wondering what the purpose of such is. My understanding of syphon flows tells me that the intermediate position of flow tubing doesn't affect flows: only the height of fluid in...
