Mel is a tour guide for The Kölsch Crew. Why she does it and what she loves about Cologne, she tells you here:

Where are you from?
Born in Cologne with Irish roots (Kölsch blood and Irish heart).
How did you get to do brewery tours?
Ask the boss: I lent Michael my voice for a tour one day after a local song contest event, because he had sung his away.
Why do you enjoy guiding people through Cologne's brewhouses so much?
I simply enjoy giving people a fun time in a wonderful city and at the same time bringing them closer to our unique culture. The Cologne way of life is really unique.
What makes Cologne special for you?
The cologne feeling, the attitude towards life, the local songs and of course Kölsch!
Oh and I forgot to mention the carnival, the Cologne Cathedral and the Rhine....
Where can you be met for a private Kölsch?
You can find me in front of one of the many small corner stores enjoying a roady. Come on a tour with me and you'll learn about that culture!
What are your must-eats in Cologne?
Well... Cologne's cuisine is hearty and delicious. Mettbrötchen (raw minced pork on bread rolls) and Rievkooche (local potato pancakes) are something special! Oh yes, and the Rhenish Sauerbraten (if possible from horse meat).
What do you have to see (apart from the cathedral) in Cologne?
The Cologne brewhouses, of course! But even apart from that Cologne has a lot to offer! I think my recommendation would be individual according to the interests of my counterpart. However, the KölnTriangle and the Chocolate Museum are must-visits!
