I would increase the OG by at least 5 points to meet guidelines and from personal experience I would halve the Melanoiden addition or leave it out completely.
I find that much Melanoiden in a delicate beer like a Kolsch can be a bit overpowering.
These are my views only. :cheers:
The worst thing that can happen if I die is that my wife will sell all my brewing equipment for what I told her I paid for it

Thanks dicko! I read up on the style and found this link at BYO https://byo.com/brown-ale/item/1881-koe ... le-profile.
I will update my recipe, to a OG of 1.048 remove the Melanoiden addition. Wheat will be around 9.5% and the article above
says max 5%, but I think I will stay at 9.5% and if it's good I'll do it again with 5% and see what the difference is.

Argh, was done about 01:30.. Everything went by plan, pre-boil gravity (1.042) / Volume (25.4L) was good,
didn't sparge. And OG.. Yeah.. I was tired.. I forgot.. fsck.. :oops:

Is there a way to calculate what the OG could be just from the volumes?

Pre-Boil: Gravity: 1.042 Volume: 25.4 l
Post-Boil: Gravity: X Volume: 23.4 l

25,4 x 42 = 23,4 x ? ==> (25,4 x 42) / 23,4 = 45 ==> OG = 1,045

assuming volumes are at same temperature ofcours.

Do you have two temp probes to measure both fermenter temp and ambient fridge temp?
