I have a lambic that has been sitting for a year and I am going to add some cherry puree to make a kreik. I plan on racking about 3g to the cherries and leaving the rest.
I have a couple cans of the vinters reserve cherry puree from NB
For you guys that do sours what amount do you suggest for roughly 3 gallons? Also what kind of head space should I leave for the restart of fermentation from the bugs?
I have heard to use about 25% of puree to pounds of real fruit. For those that have used real fruit how much did you use?
