Secondary fermentation from fruit

So I just added 3.6 lbs of semi frozen  wild huckleberries to5 gallery of a blonde ale. I let primary go for 2wks and it reached its expected fg. Should I expect any significant fermentation now, with the new juice?

You will get a secondary fermentation from the fruit, even though most of the additional alcohol will be negated by the water in the fruit in terms of overall abv%. I’d give it a couple weeks after adding the fruit ,then verify FG.

Ok thanks

+1  on tap at my house now is a mosaic IPA that i racked onto 3lbs of blueberries in the secondary.  FG when i added to the secondary was 1.014.  After two weeks on the blueberries I racked to a clean carboy and cold crashed before kegging(wanted a clear pretty beer on tap) and final gravity dropped from 1.014 to 1.012- although I only kept it in the primary for 7 days…

Pretty beer !

Yep.  I usually give my fruit beers 2-4 wks to ferment and condition again after adding the fruit.  This allows the extra fruit sugars to be fully fermented and allows the beer to clear a bit as well before packaging.
