Great news everyone 
This feature is now live and ready to use! During the racking process, you’ll get the option to enter your own best before date to use. If this field is left blank, Breww will continue to auto-calculate the date for you (according to your rules).
We hope this saves you time 
We’ve also included some improvements to how we handle racking into tracked casks/kegs that Breww didn’t think were empty. This was a common cause of mistakes - clicking through without reading exactly what was happening - so now you have to be more explicit that you’d like Breww to empty them (or not to).
