Kegging, canning or bottling? Have you considered the benefits of Murphy’s Super F?

Since its launch,  Super F has proven invaluable to many of the top craft breweries worldwide, providing great results for beer produced for keg, can and bottle whether filtered or unfiltered.

What is it?

Super F is a rapid action fining, made using our own special formulation of silicate and polysaccharide for rapid sedimentation.  This unique blend makes Super F effective at fining out yeast as well as being an effective finings agent against potential haze forming colloids like proteins.

How’s it used?

Super F is best added when beer is moved from fermenting vessel to conditioning tank with care taken to ensure good mixing.  It is not a suitable addition for cask conditioned beer and should never be dosed directly to cask.  Action of this fining is quite rapid with excellent results achievable within 48 hours.  Super F packs a real punch so dose rates are low with typical doses 75ml-175ml per hl will achieve great clarity (often less than 1 EBC) and a compact sediment.


The rapid action of Super F will significantly reduce residency time in conditioning / maturation vessel.  When using this product, the load on centrifuges and filters will be significantly reduced due to brighter beer being presented for further processing.  This gives considerable time and money savings per run.

When kegging unfiltered beer, yeast counts and protein content in the product will be lower and more consistent, leading to a more stable product.

Super F is also vegan friendly and is easy to store (just don’t freeze it!) with a shelf-life of 6 months from manufacture date. Furthermore, Super F is also in accordance with German Purity Law (set into force by the German provisional beer law in its current version 9 [6]).

Finings trials

Introducing a new finings regime to any brewery is a big step.  At Murphy and Son, we pride ourselves on our technical support so before any brewer uses this product we ask that they send a representative two litre sample of their beer to our laboratory where our Research and Development Scientist Dr Ruth Newby and the rest of the lab team will set up optimisation trials.  This will give valuable information on haze and sediment levels for different dosages to provide a starting point for trials and additions in the brewery.  As always, our technical sales team will also be on hand to aid and advise on the products use.
