Thank you for reporting this. It’s not really a bug but unwanted side effect of the fixed limits in this game and of the fact that productions have to follow a certain limit. In this case even just gathering alcohol from outside follows the alcohol limit. There are many more tasks that should better not use a limit, like emptying storage or filling a clay spot. I can fix it by using one of the custom flags for those tasks but it will need a complete rework of resource categories and is something for a bigger update.
