Chapter 9, The Hobbit

From the text:

“Now come with me,” he said, “and taste the new wine that has just come in. I shall be hard at work tonight clearing the cellars of the empty wood, so let us have a drink first to help the labour.”
“Very good,” laughed the chief of the guards. “I'll taste with you, and see if it is fit for the king's table. There is a feast tonight and it would not do to send up poor stuff!”
