I had been planning on writing a post about optimal beverage serving size, but thankfully Mr Baldwin wrote about it so I don’t have to:
When Coke [was] sold in 6 oz. bottles it was billed as the “pause” that refreshes. Now it’s a motherlovin’ sabbatical.
Personally I vote 250ml (“energy drink size”) is the absolute perfect amount. You get a good swig, but you don’t feel like the drinking process is taking up the whole afternoon, and there’s room afterwards for if you need to drink something else to wash the taste of the first drink out. What do you kids think.
