   1. L:G ratio and enzyme stability

      Just read on another forum that there is some thought that indicates liquor to grist ratio can affect enzyme stabilty at various mash temps and therefore fermentability results.
      
      I thought that if this is so it could be due to a higher ratio leaching the enzymes away from the starches concentrated in the grains and into the liqour where the starches are more diluted. I was questioning (to myself) whether this would be percievable in the finished product and/or whether it affected the...

      Thanks guys. Will go through those links shortly. I'm happy with my results so far and wasn't really worried, just trying to further my knowledge so I can talk comfortably about technical aspects with 3v brewers

   2. Word is out on BIAB

      Word is obviously out. 8&1/2 months to get first 560 members, 3 months to get next 560 members, growth at this rate will have some sponsors wanting to come on board.
      
      Now's the time to get Nanna cranking out bags with the sewing machine.
      
      Or perfect that SS auto syphon Wizard78 :smoke:

      Well-spotted Mick and thanks for working that out. I hadn't realised the 'curve' was that great.
      
      Very shortly, we'll be looking for volunteers to work on various projects to improve the site. One of these projects will be aimed at finding clever ways to fund the site to avoid relying on sponsors. We have always intended to sell BIAB bags to help fund the site and also provide a uniform bag that will give us better consistency between BIAB brewers. This is just one of many projects that needs...

   3. Just starting to apply some science and use calculator

      I am just measuring up to my 4th and 5th BIAB brews.
      
      I have just started to use the Biab calculator
      
      As I already had purchased both grain bills pre milled I assume I just adjust Brew length until the grain bill size roughly meets the amount of grain I have, then use the water volumes specified and massage the hops to get desired IBUs.
      
      When I do this the calculator gives me a lower output (even with a higher efficiency) than the original recipe suggests. 20l versus 17.5. Am I missing...

      Great to see that made some sense Mick. Any time I write a long post I get scared :?. There's a fine line between offering necessary detail and writing nonsense. So, posting is usually scary for me :lol:
      
      :whistle:

      P.S. Will look forward to seeing how the next set of figures turn out.
