So I have my first lambic sitting in the closet for over a year now. It is really really funky however not very sour at all. I think the alcohol got a bit too high for it to really sour (I think it is sitting around 8% or higher IIRC). I though about adding some raspberry puree to get some tartness into it. My questions is how much flavor will be left over or will the bacteria just kind of break down whatever flavor contribution the raspberries would give? Also this beer thinned out quite a bit sitting at 0.998 current gravity. Will adding this raspberry puree further dry it out? And finally how long should I let it sit on this fruit puree?
