Harnak Spirit bottles won't stack, unlike their other brewed counterparts.

I believe most of those drinks are made by design to not stack. I'll edit this if I can find the link from when they were added to the crafting but there has been at least one discussion thread about it as well.
For balance reasons most of the new drinks should not be stacking.

If you try to chug these, you'll literally die! Stacking here is only handy for people who want to sell them, etc.
