I normally go 10 days on fruit puree temp controlled, starting about a week into the primary ferment. I recently used a can of the Vintners Harvest raspberry puree for 5 gals of my 10-gal batch of oatmeal robust porter, and it was done after probably 5-6 days.
I used 4 pounds in a 5 gallon batch in secondary and it had plenty of mango flavor. Tasted great. First time I did it with a citra pale ale, right now I have 4 lbs aging in a 5 gallon carboy of tripel.
General rule has always been 1-2 pounds of fruit per gallon but I sometimes find that 1 pound per gallon can actually be too much depending on what you are going for. I prefer subtlety.
Hi Keith, I’m curious - do you first pasteurize the homemade Costco puree before adding it to secondary, such as stovetop @ 150F for 20 min, cool and then add? I’d have to double check the temperature I use but that is my normal procedure when using homemade puree.
That sounds good. I’ve used fruit before, but not mango. I wasn’t sure if it would end up being mellow or not. I’ll be using a pile of Citra in this beer as well. I don’t want too much either, but I certainly want enough in there to accent the habanero.
Do you think there is any additional fruit flavor extracted for a letting the beer sit on the fruit puree after it is done fermenting?

Yes, to a point, which some in the know put at about 10 or maybe up to 14 days total on the fruit. Otherwise there is a potential for sliminess and/or contamination/off flavors.
YMMV depending on the fruit and its origin.
edit: personally, I recommend pasteurizing fruit puree used if it doesn’t come that way.
