That’s where brewing apps come in handy: they do a lot of the calculations so you can focus on designing and scaling your recipes. These tools will also guide you through all of the timing on brew day, making them especially helpful if you’re a beginner.  Creating a recipe is easy—just add the ingredients (fermantables, hops, and any other additions), and the size of your batch. The app will automatically make all the calculations for you, including the amount of water you have to add, for example. When it’s time to brew, Brewfather will create all of the timers you’ll need, complete with a schedule of when you’ll need to add in all of your components.  To save you some time, the platform is also constantly updating its extensive library of ingredients, which includes all the relevant statistics for each one, like yield percentages and IBUs. Just search for your ingredients and the platform will take them into account automatically.  Brewfather is available for free for Android, iOS, and on the web.
