There are days when you feel like a bath full of beer, not just a glass.

Now you can have both -- thanks to a German brewery that has developed a beer you can use to wash down your food or wash down your body.

Klosterbrauerei, or "monastic brewery," was looking for ways to mop up excess capacity in a slumping beer market and struck upon the bath-time supplement to help tipplers soak away their stresses and strains.

The brewery, in Neuzelle, near Leipzig in eastern Germany, says the dark brown brew has restorative powers for both the mind and body to improve the skin and pep up spirits.

"It opens up the pores, the yeast penetrates the skin and after 15 minutes your skin feels softer everywhere," said company spokesman Dirk Vock.

"It is also a good remedy for people with skin problems," he said.

"The beer cloaks bathers in a delicate aroma of malt," said Vock, who recommended about three liters of beer per bathtub.

But Klosterbrauerei, which showed the bath beer to shoppers in Leipzig last week, said those taking a boozy dip would not end up with a telltale odor.

"When you get to work, you won't smell like you've just emerged from the corner bar," Vock said.
