Let's brew!

Paul and Max try a new beer.

Paul: Yuck, the roast malt is scratching the back of my throat. Makes me want to throw up.

Max: Great coffee aroma, deep, dark, aromatic intense!

Paul: Is this also a sour? Help! My beer has gone bad!

Max: Sour aftertaste. Very refreshing! Excellent!

Paul: Let's brew our own beer! Can't get worse than this!

Max: Let's brew our own beer! Like this, just with more coffee and really sour!
