I have been planning to brew a Kolsch for my next batch. While doing some research I ran across Kolsch Malt from Global. Have any of you KGB'ers used this malt before.
4.5° L. From a maltster co-op based in Osthofen, near Köln, this malt is used by some of the brewpubs in that city to make their trademark ale. Kölsch malt has a light, sweet and extremely "German" flavor and aroma with a little bit of biscuit character. We've had good results using a multi-temp step mash with Kölsch malt, but a single infusion — although not traditional — works as well.
Style nerds please take note: the maltster rates the color of this malt at 9 EBC. If you use 100% Kölsch malt for the grist of a Kölsch, you will be within spec according to Eric Warner's Kölsch (7-14 EBC, or 3.5-7 SRM — p. 51), but definitely on the dark end of the BJCP guidelines. If you are brewing for a competition, you may want to incorporate some pils or wheat malt into the grain bill to dilute the color.
I talked to Phil and he said he has ordered that malt before. He seemed kind of reluctant to order again unless there was a bulk involved. Would any of you be interested in cooping in a 55lbs bag with me....there is no way i can go through 55lbs by myself.
Here is the recipe I was planning on using with this particular malt. Let me know what you think...recipe check....and if you have a ribbon winning recipe, please dont be bashful and share. Thanks!
