I'm gradually progressing to my goal of AG brewing and am now entering the full boil stage (factoring hops utilization, fermentables, etc.) and recipe creation. I know there are several calculators out there like BeerSmith, ProMash, etc., but was wondering if anyone can vouch for the free calculators that are available like TastyBrew or QBrew - to name a couple- or if there are any out there that are more highly recommended yet free? Right now I'm leaning towards TastyBrew due to simplicity of use and overall layout (QBrew is a little difficult to navigate and not intuitive).
Any recco's or comments regarding TastyBrew's reliability would be appreciated.
