Frozen Fruit additions, and impact on ABV?

[fendersrule]

86oz of raspberries.

will need to pasteurize.

Question:

Will all this mashed fruit "sink" in a Muslin sock, or will it float?

If it floats, is it simple physics that the weight of the object tied to the bag to sink it needs to weight more than the bag/contents itself?

I didnt use a bag but after about 1 week the berries floated to the top. I swirl the fermenter couple times a day . But you could weigh it down to prevent it from floating up.

Fruit will float. You can weight it down with a (sanitized) glass or stainless steel object of some kind.

is it simple physics that the weight of the object tied to the bag to sink it needs to weight more than the bag/contents itself?

No.
The fruit floats because CO2 bubbles get trapped inside or otherwise adhere to the fruit pieces.

Think a bag of marbles from the dollar store should do it?

 

[RPh_Guy]

Just guessing but I think 0.5-1 pound should be fine.

Not sure tbo. Who knows what those are made of , especially if made in china . I've used shot glasses and now use stainless washers

 

[fendersrule]

I would hope that they are made out of glass!

Fermentation as of this morning is now on the down-turn. Still going, but it's lessening. Imagine I'd probably toss everything in tomorrow.

Going with 1lb per gallon. Will let that ferment for a 10 days or so, then will dry hop 5-6 days before bottling.

 

[fendersrule]

Yay. Successful and no hiccups.

 

[fendersrule]

I introduced all that to the wort while it was still pretty worm, probably 130F or so. Should be OK I suppose....raised the temp of 5 gallons from 65 to 68.

Bottled today.

WONDERFUL beer. One of the best I've made. I will update the original recipe thread noting of this success.

Raspberry amount was perfect. It wasn't tarty, which was my worry. Beautiful red color. The balance is really nice.
