The Kölsch is warm fermented beer with top-fermenting yeast, which you then conditioned at cold temperatures like a lager. This recipe from The South Yeasters Homebrew Club is a version with more aroma hop additions.

HERE’S WHAT YOU WILL NEED
About the process: During the boil you can add one teaspoon of Irish Moss at the last 15 mins of the boil, which will allow for a clearer beer. It is not an essential ingredient, but it will give better clarity. The hop additions are kept to late, for better flavour extraction and less bitterness.
Water: Filtered water is best, with a PH of between 5.2 and 5.7. This recipe uses about 31 litres, depending on your equipment losses.
Malt Bill: The addition of flaked rice lightens the body of this beer.

Hop Bill: The late additions will give better aroma retention, with less bitterness. Dry hopping for 4 days before bottling, is the ideal way to extract more aroma, but too long will lead to "grassy" flavours, so make sure fermentation has finished before dry-hopping.
