Problems with trying to create a Wheat Berry Beer

[jpitz31]

Hey all, I am trying to create a wheat berry beer. I have some pasteurized black berry juice with sugar. I ferment the beer normally and then transfer the beer to a secondary. I add several ounces of the blackberry juice to the beer and let it set for several days.

It appears to continue to ferment and as a result the beer starts to taste a bit sour like wine.

I do not want to add Potassium Metabisulfite or Potassium Sorbate as I hear it can cause allergies for some people.

Would back sweetening be a better choice or is there a better way?

Cheers

Joe

I've never heard of this before...there are a few options you can do.

1. Next time add the berries during the mash, mash and boil or just boil. You'll get some flavor that stays around after fermentation. DFH brewery is known to add fruit during all parts of the process.

2. Add the berry juice in the keg or add juice to individual glass.
