Whirlfloc Tablets

Whirlfloc is a concentrated kettle fining agent made from refined carrageenan (seaweed extract) that dramatically improves beer clarity. Added in the final 5–15 minutes of the boil, it binds to haze-forming proteins and beta-glucans, encouraging them to clump together and settle out during the whirlpool and cooling phase — leaving you with a brighter, cleaner wort and less trub loss.

How to Use

• Add 1 tablet per 10–15 gallons (or ½ tablet for 5-gallon batches) in the last 5–10 minutes of the boil
• No rehydration needed — drop it directly into the boiling wort
• Works across all beer styles, from crisp lagers to full-bodied stouts

Why Whirlfloc?

• More concentrated and consistent than traditional Irish moss
• Creates a tighter, more compact kettle trub — meaning less beer loss at transfer
• Reduces chill haze for a polished, professional-looking final product

Pro Tip

Tablets can sometimes crumble when cut in half. If that happens, don't toss the pieces — add the crumbled half to your first brew and save the intact half for your next batch. No waste, no fuss.
