Change in creation of recipe - Type of mail insted of specific manufacture
It could be smart if design of recipe was made based on malt type and the same for hops.
Manufacture might change and for hops the year and hop alfa value/ % change
So if it was possible to have a middel step - so when you press brew you can choose what malt to use - and also the posibility to make a split to use the rest of one manufacture and last part from another manufacture.
