Getting ready to brew next weekend.  Formulating the recipe in BrewSmith.  I have both Whirfloc and Irish Moss on hand.  Is it redundant to use both?  I've only recently acquired the Whirfloc tablets, but also have Irish Moss.

redundant, too much can cause good stuff to be lost

 

use up your IM first, remember to hydrate first, also when you do use Whirlfloc it's 1/2 a tablet at no more than 10 minutes in the boil 7 is better.

Sorry to disagree with Mic but first... throw your Irish Moss out the window. Next, use the Whirfloc as Mic suggested. I don't bother using a half tablet, I just throw the whole thing in when I'm 7 minutes from flameout. It's something like $1.29 for 12 tablets so cut them in half if you want but using the whole tablet is just fine. Allowing the brewpot to settle a little bit after chilling gets everything to drop and then I usually rack from brewpot to primary to leave as much schputz behind as possible.

I'm with Ken. I got on a whirlfloc bulk buy and got pretty much a lifetime supply for less than $20. Easy to use. I use 1 tab per 5g.

you are both using too much 

[Deerslyr]

So noted. I'll start another thread about the recipe.

[BlKtRe]

Says who? My beer or the manufacturer? I'm not about to take the time to cut the tabs when it works perfectly fine using whole tabs.

My pro brewer buddy say to add it between 20 and 15 to let it do it's thing. Why 7?

I read some time ago a statement by the manufacturer that it is intended for no more than 10 minutes in the boil, and that the recommended dosage is 2 tabs of 20g per 100 Liters, 1/2 a tab is close enough.

Apparently anything over 10 minutes causes degradation of the carrageenan.

[BlKtRe]

I toss mine in at 10. Seems I read the same thing at some point.

I'm not why this would be an issue. Once the proteins have clumped and dropped, it has done it's job.

there was also something on it precipitating FAN as well

That's something I don't recall. Excellent benefit then.

I used to do 5 minutes and then someone said 10 and then someone else said the kill zone seemed to be 7 so that's what I did. It definitely works because I brewed a batch once last year with no Whirfloc and wow, big difference. Also, trying to cut a tablet in half would probably leave you with 9 tiny clumps and some dust. It's kind of 'crumbly' so I can't see trying to cut it in half. Somewhere in there I also got SUPERMOSS which is a pain to prepare (okay, not really but it's not as easy as dropping a tablet in the brewpot) and it didn't work as well. Whirfloc is for me.

+1 for the 1 tablet per 5-gal batch at 10ish minutes

not too hard to cut in half

[Mya]

not too hard to cut in half

what we homebrewers need is a whirlfloc powder that can be measured out exactly based on volume vs gravity, that doesn't require elaborate preperation

I just snap them in 1/2 with my fingers. Sure it isn't exact, but it is easy to do. I throw it in a 5 mins.

[Mya]

huh

 

it seems there are several formulations of Whirlfloc on the pro brewer market, T which we use in tablet form, B which is a powder like Super Moss, and G which is a Granular form.

 

all three have differing pitching times and methods for preparation
