In Germany, beer consumption is up as temperatures remain unusually high. This is good and bad news for the beer industry.

While the breweries have more than enough beer to go around, they’re running out of bottles because customers are not returning their empties quickly enough.

Germans care about the environment about as much as their beer; that’s why the glass bottles are recycled. Customers pay a small deposit on each one, which they get back when they return it to a store.
