A couple so far are:
1. I can't specify how many time I want to batch sparge...1, 2, 3, etc. so I need to take the total sparge water volume, and devide it by the number of sparges I do.
2. When formulating a recipe, the software calculates many things, like estimated ABV. It also estimates final gravity. This isn't really a bad thing, BUT if I stop fermentation before it finishes up itself, I get a lower ABV, but the software shows what it estimates, which can put the brew in a different style.
I ran into number two when inputting a recipe for an english special bitter I just brewed. The estimated final gravity pushed the ABV above the style....but I stopped fermentation above the estimate, and the fina ABV does fall within the style.
3. When inputting actual measurements, the style guide comparison chart still shows the estimated values, not the values I input, so the comparison chart is then considere inaccurate....to me anyway...I don't care what it estimates so much, I care more about what the actual values are.
That's what I've noticed playing with it for 30 minutes.
BTW, the iphone version app sucks. I can look at recipes, but no detail whatsoever.
