Greetings from Fort Collins Colorado. I was looking for a fairly simple, web based, brewing calculator and so tried out Brewer's Friend on my 26th batch. I found it simple to use and accurate and the printed reports were clear and easy to follow. I also found the water adjunct calculator to be spot on accurate based on what my PH meter was telling me unlike a spreadsheet water calculator which I purchased a couple of years ago. If I had one enhancement request, it would be to enable a user to print a summary report on the water calculations that show the amount of salts and acids to be added to the mash and sparge water.
