To solve this puzzle, you should be looking at the two pages in the booklet with a tan background, showing 9 bottles of wine.

There’s a tan circle on the left-hand page. What might that circle suggest?

Is there an object inside the box that could be useful here?

Grab one of the coasters and place it on top of the circle. How might the coaster relate to the bottles of wine?

The coaster shows 4 glasses of wine. Can you figure out which bottle corresponds to each glass?

Start with the leftmost glass. It shows a white wine. There’s only one white wine shown in the booklet, so this must be bottle #3.

Continue on to the yellow glass. Which bottle might this glass have come from? Look closely at the glass…

The glass has bubbles. So it must be a sparkling wine (bottle #9).

Onto the third glass. Which of the red wines might this be?

Bottle #1 says “don’t serve with bread.” There’s a loaf of bread shown on the coaster, so it can’t be that bottle.

Bottle #5 says “don’t serve first.” This one is a candidate.

Bottle #7 says “don’t serve with sparkling wine.” The second glass is a sparkling wine, so it can’t be this bottle.

By process of elimination, that leaves bottle #5.

Finally, look at the last glass (the pink wine). Which bottle did it come from?

Bottle #2 says “serve with a floral wine.” The glass of yellow wine has floral notes, so this bottle is a candidate.

Bottle #4 says “must be the only Crete wine.” The red wine (#5) is from Crete, so this glass can’t be from bottle #4.

Finally, bottle #8 says “serve this last.” So far, so good. But the bottle has bubbles, while the glass does not.

By process of elimination, this glass must have come from bottle #2.

You’ve identified the glasses as bottles 3, 9, 5, and 2. What might you do with those numbers?
