Whirlfloc Tablets (10 Tablets)

Why Choose Whirlfloc Tablets?

For brewers aiming for crystal-clear beer, Whirlfloc tablets deliver a natural and hassle-free way to improve clarity. Each tablet contains a precise blend of Irish Moss and purified kappa carrageenan, two seaweed-derived ingredients trusted for their clarifying properties. Manufactured in GMP-certified facilities, these tablets are a staple for homebrewers and professionals alike. Whether you're brewing a lager or a pale ale, Whirlfloc helps you achieve that professional polish.

What Is Whirlfloc?

Whirlfloc tablets are a specialised fining agent designed exclusively for brewing. They combine Irish Moss (Chondrus crispus) with purified kappa carrageenan, both naturally sourced from seaweed. Irish Moss, a red seaweed harvested from coastal waters, is prized for its carrageenan content—a polysaccharide that binds with haze-forming proteins. This product is intended for brewing uses only, offering a convenient tablet form that simplifies dosage and reduces mess.

How Whirlfloc Works in Brewing

During the boil, proteins and polyphenols can cause chill haze and reduce beer clarity. Add Whirlfloc in the last 10–15 minutes of the boil; the carrageenan reacts with positively charged proteins, forming larger complexes that settle during cooling and fermentation. The result is a brighter, more stable beer with extended shelf life. The tablet ensures consistent dosage without the need for scales or scoops.

Benefits for Brewers

• Improved Clarity: Whirlfloc effectively reduces haze-causing proteins, giving you a brilliant, clear brew.
• Enhanced Stability: Removing excess proteins helps prevent chill haze and prolongs shelf life.
• Convenient Form: Pre-measured tablets eliminate measuring—just drop one into the boil.
• Natural Ingredients: Irish Moss and kappa carrageenan are natural seaweed derivatives, suitable for many beer styles.
• Cost-Effective: A practicable solution for both small and large batches, without breaking the bank.

How to Uses Whirlfloc in Brewing

For best results, add one Whirlfloc tablet per 5 gallons (around 19 litres) of wort during the last 10–15 minutes of the boil. You can crush the tablet for faster dissolution or add it whole. Stir gently to distribute evenly, then proceed with cooling and fermentation. Whirlfloc works well with post-fermentation finings like gelatine or isinglass if extra clarity is desired.

Ingredients Explained

Irish Moss (Chondrus crispus): This red seaweed has been used for centuries to improve beer clarity. It contains carrageenan and trace minerals that aid protein coagulation, enhancing stability without affecting flavour.

Purified Kappa Carrageenan: Extracted from specific seaweed species, this refined polysaccharide forms strong gels with proteins. It provides reliable clarification across different wort compositions and imparts no off-flavours.

Frequently Asked Questions

When should I add Whirlfloc to the boil?

Add it during the last 10–15 minutes of the boil. This timing allows the carrageenan to dissolve and react with proteins before cooling.

Can I uses Whirlfloc with other finings?

Yes, Whirlfloc complements post-fermentation finings like gelatine or isinglass. Uses it in the kettle for initial clarity and fine again later if needed.

Is Whirlfloc suitable for all beer styles?

Whirlfloc is effective in most styles where clarity is desired, such as lagers and IPAs. Avoid it in styles where haze is intentional, like New England IPAs or wheat beers.

How should I store Whirlfloc tablets?

Store in a cool, dry place away from sunlight. Keep the container sealed to prevent moisture absorption.
