So I tasted my blueberry wheat last night after almost two weeks bottle-conditioning. When I first tasted it before bottling it definitely had a "Flinstones vitamin" aroma to it. I was a little worried I would still get that, but after bottle conditioning I did not.
The aroma was definitely all blueberry, not too strong but you can definitely smell it. After my first taste I was so happy, it tastes awesome! The extra addition of raspberry adds a little bite to the blueberry, which was what I was going for. The color was a little purple because of the red/blue color mix of the fruits. But I'm extremely happy how it turned out. Here are my notes of what I did in case some are curious.
4 lbs of fresh-picked frozen blueberries
1 lb of fresh-picked frozen raspberries
"Pasteurize" for 15 minutes at 170 deg. F, enough water to just cover all the fruit
Poured into the bottom of a 5 gallon glass carboy, let cool for a while
Siphoned my wort from the primary to the secondary
Conditioned for 2.5 weeks in the secondary
