Opinions about either? Do you use one over the other?
I use Irish moss in the kettle. I want to try whirlfolc tabs, but I bought a few ounces of irish moss a while back. I am almost done with the irish moss and was going to purchase a batch or two worths of whirlfloc. I also have never re-hydrated my irish moss prior to adding it to the kettle I have heard that improves its results as a clarifier.
I tend to do a 90min boil so that helps a lot with clarity anyway.
I haven’t used either, so I’d be interested to see peoples opinions. My first brew was pretty basic, so I didn’t think about it. My second was a wheat ale, and that’s supposed to be hazy. Both came out all right without it, but there are a few I’d like to throw some in for……
I’ve used both….I have Irish Moss on hand and sometimes if I order a kit it comes with the Whirlfloc tabs. I’ve noticed no real difference in the two, more just a personal preference…..here is some specs on it. It seems to be just a processed Irish Moss product. The rehydrating thing is something I’ve seen also….might have to give it a go…..
Product Data Sheet
Product Name: Whirlfloc BWS
Product Code: 5B06797
Date Printed: November 09, 2004
WHIRLFLOC BWS is an Irish Moss based kettle coagulant designed to increase both hot and cold breaks in the wort.
Because the carrageenan present in the Irish Moss helps remove colloidal material which would otherwise be
present in the beer, the beneficial effects of WHIRLFOC B are also observed in the fermented beer.
WHIRLFLOC BWS was developed not only to increase clarity in wort and beer but also to help increase the
compactness of the hot break of the wort.
Studies have shown that improved wort clarity with WHIRLFLOC BWS leads to a cleaner fermentation and markedly easier filtration of the beer after it is fermented.
WHIRLFLOC BWS is classified as a processing aid for beer production. It reacts with colloidal, haze promoting
material in the wort and is removed with this material by settling or filtration before the beer is finished and packaged. It does not remain in the beer.
Appearance : Free flowing tan powder
Aroma : Slight seashore aroma
Solubility : Almost completely soluble in hot water
The ingredients in WHIRLFLOC BWS are appoved for use in brewing and are listed in the Adjunct Reference
Manual of the United Sates Beer Institute. It contains the following components:
Sodium bicarbonate E500

Thanks for the technicals on whirlfloc. I was going to do a search but….no I don’t have too. i use loose irish moss since i can buy a crap ton of it in bulk for wicked cheap. the tabs are more expensive and are the same thing anyway, so i don’t bother.
i have never rehydrated the moss, may have to try it and see if it is more effective that way.I had only recently heard of rehydrating the Irish moss. Supposedly it is more effective that way. Some people like the tablets because the irish moss component in them is ground up, so it hydrates itself quicker in the pot…
I plan to try the rehydration thing sometime too, if I remember when I am brewing. I have been using Supermoss, 1/2 tsp to 5gal, and put it into the wort I pull out for my pre-boil gravity. I take the draw that I put in my hydrometer into the fridge,cool down for a half hour hydratre the supermoss, then add it back to the boil fifteen min before flameout. It kind of works like a roux in cooking, never want to add it directly to hot or it will clump up and you will not get a dissolved effect. My last IPA came out crystal clear and that was after dryhopping.
so far i’ve only used Irish Moss, i do want to try the tabs but i have a boat load of moss to go through

I hadn’t thought of using the pre-boil sample… good tip thanks.
