CaCl can go into the mash water. CaCO3 often needs to go into the mash to dissolve. My mash conditions never need Gypsum, so I've never added it to the Mash nor the water that goes into the mash. When I add Gypsum for an IPA, It goes in the boil kettle, because It's for flavor, not mash conditions.

Adding sufficient Ca, controlling mash pH to minimize tannin extractions, using Whirlflock in the last 5 minutes of the boil, and getting a good chill are the best ways to reduce chill haze, I think. If you want, you can make a clear wheat beer.

Thanks,

I'm using Irish Moss. Is WhirlFlock more efficient ?

I usually chill in 25 minutes to room temp.
I'll be doing 10 gal eventually but with 50ft copper coil instead of 25ft like my past batches, should I go with a plate chiller or something ?

Also, is there any filter or strainer I could use to transfer between the kettle and the fermenter ? I'll be using a converted 50l SS keg with a ball valve, and I'd prefer racking in a closed environment than using a standard racking cane from the top, since contamination is critical at this point.

Thank you,
Jonathan

I've heard tell that whirlflock is more efficient, but I've never seen any hard evidence. With Irish Moss, it can help to rehydrate well ahead of time. Start the rehydration when you first set up for the day so it gets a few hours.

Rehydrate ?

You mean the Irish Moss ?

I used to put 1 teaspoon in the brewpot 10 minutes before boilout...

Any idea for racking from the keg ?
