Well I posted a while ao asking about the effects of adding grapefruit or another citrus fruit to secondary fermentation. People seemed to be cautiously optimistic, although there certainly were concerns about citric acid. Someone suggested it might kill the yeast. I was in my LHBS yesterday picking up ingredients and noticed they sell bottles of citric acid! What is that used for? How much is it used? In what quantities? I figure if reasonable amounts of CA are healthy in a brew, I might just go forward with the Grapefruit IPA.

Also on a side note, what is the procedure for adding fruit in secondary. Some seem to like to boil it with water and then add it, others, to freeze it. Also, how is it removed? Do I re-rack my beer? Thanks!

I don't have a clue as to the effects of citric acid but since you'll be using a ton of hops anyway, Cascade would definitely impart a citusy aroma.

Citric acid is used in Winemaking and Meadmaking. I have not heard of anyone using it in ales/lagers.

It is a fairly common addition to meads, however.

citric acid does not interfere with fermentation - i made a hard lemonade clone with frozen concentrated lemonade which included citric acid and it fermented great for over a month

Well, that's the go-ahead I needed. Onward towards the Grape-fruit IPA!

I remember reading somewhere that it's used in small amounts to invert sugar.

True! The acid helps with the process. I squeeze of lemon works just as well.

I think I'd just boil some grapefruit juice a couple minutes, cool and add to the secondary or at bottling/kegging.

Would the rind of the grapefruit give you the flavor you are looking for? With oranges, there's a lot more flavor in the rind (just the outer, colored layer of the peel) than in the juice; wondering if the same holds true with grapefruit.
