Sugar Content of Raspberries

Does anyone out there know how much sugar/lb (or any other mass or weight measurement) is in raspberries? I've made a historically well recieved Honey Wheat Raspberry high alchohol beer. The problem is that I add the first of two frozen raspberry additions after the fermentation has began. I do take an o.g. reading post cool out of the kettle, but it obviously doesn't account for the raspberries. I'd like the folks at my niece's 21st b-day party to know how much of the booze they're consuming.

There is very little sugar, thats all I can say. Even with two raspberry additions (even large additions), I would imagine your gravity wouldnt go up more than 0.5%. Sorry I'm not of much help, but fruit additions are not where you get much of your fermentables, and raspberries aren't a very sweet fruit.

Not to mention it will vary every year .

I did a Google search and found a reference that said raspberries contribute 1.003/lb according to ProMash...FWIW...

Hello George,

I see now that you posted this in 2005, WOW!
I make a high gravity raspberry honey wheat as well. I also make lots of fruit wines, beers and ciders.
Here is a chart with approximate sugar levels.
Note: Sugar level changes everyday until harvest and some after also. That's why wine grape harvesting is a science and art.
It is best to check the amount of sugar in the fruit with a refractometer but for estimated gravity and estimated additions this will hopefully be helpful to fruit beer and wine makers.

Update,
Dried Cherries (not listed above) are 69% sugar by weight.
This is "Whole Foods Sour Tart Dried Cherries"; so 100 grams of cherries would be 69 grams of sugar, or 1lb would be 11.2 oz of sugar. So be forewarned that dried cherries add a lot of sugar/alcohol to your beer. Cheers!
