Brewhouse Efficiency
« on: December 07, 2009, 08:40:07 PM »
I read in a previous post that you were considering an alternate to brewhouse efficiency using mash efficiency and equipment losses separately.  It seems this is a easier approach for most homebrewers to grock.  Is there still a plan to do this?

Brian,
  I was looking at using mash efficiency and then calculating forward from there, but this would be an option to the standard brewhouse efficiency and not a generaic replacement.

I don’t think you need to completely change the methodology. How about just providing a way to estimate Brewhouse Efficiency (BE) from a user’s entered parameters? You already have equipment losses, so if you provided a place for Mash Efficiency, you could display the estimated BE and let the user choose that or enter their own value like they do now.  If you wanted to get really fancy, you could average BE’s over the last ‘x’ brew days and give them an option to use that as well.

The problem with just using an empirically derived BE is that it takes a couple of iterations to get a stable number and that balance is upset if equipment is upgraded or changed as is often the case with homebrewers.

In general, it would be nice to be able to formulate a recipe, then on brew day take the measurements that you normally take, enter them in the program, and have it show you how things went. You do this really well with gravity readings and ABV. Could you extend that to efficiency as well?

Hi,
  Actually the feature to calculate actual efficiency is already in the program.  Click on the "Brewhouse efficiency" button in any open recipe and a small calculator will be displayed to take your actual measurements and calculate the efficiency.
