Soaking raspberries in vodka?

Post #1 made 6 years ago
I currently have an oatmeal stout fermenting away that I intend to rack onto some raspberries. I've been doing a bit of research into what prep I should do before adding the berries as far as sterilising and preserving the flavours. I've read a few things on various brew forums about brewing with raspberries but not specific information on this vodka soaking method.

A mate of mine has brewed with raspberries before and recommended soaking the berries in vodka overnight before adding them to the brew. He reckoned it has the double effect of killing off any bacteria in/on the berries and it causes the berries not to impart such a tart flavour to the brew. I haven't been able to find any info to confirm whether this is true or not.

I bought the raspberries already frozen from the local supermarket.

Does anyone know anything about this?

It seems reasonable? I would check on the affects of "Pectin" in beer? It may cause chill haze? See the link below or search Google for Effects of "Pectin" in beer ... -mr-wizard

Edit,,,,, here is a extract from that article.

Cherries, blueberries, blackberries and raspberries all have a medium level of pectin. I think I see a pattern here — it seems like brewers typically make fruit beers with fruits that have a low-to-medium pectin level. Makes sense to me!
