We are pleased to announce that the shelf life of our vegan fining Super F has increased from 6 months to 9 months!
As part of this, you will now receive Super F in green 25kg or 200kg drums and the shelf life starts from the point the product is manufactured and placed in said green drums on our site. The shelf life will, of course, always be clearly outlined on the product label.
Shelf life isn’t the only change Super F has seen of late. We’ve also made it available to purchase without an optimisation by our laboratory, although we still strongly recommend you carefully optimise before use! In aid of this, we thought it advantageous that we go through the basics of a successful Super F optimisation.
First of all, the materials you require to optimise are as follows:
3L measuring jug
500ml measuring jug
Pipette with 0.1 ml graduations
5 x 500ml glass bottles
Refrigerator set to 4°C
Microscope kit and Haemocytometer
Super F Optimisation Method:
Set up the glass bottles with the specified dose rates and clearly label the bottles
Take a 2.5 L sample of beer post fermentation and perform a yeast count
Measure 500ml into each bottle and seal, invert three times to mix and refrigerate for 24 hours
Very carefully remove the beer from the fridge and set on a bench with a light source behind the samples
Select the rate which has the best clarity along with a compact sediment.
If you cannot measure haze it might be good to develop a grading system for your records e.g. A-F A=Brilliantly bright F= Very Turbid/Dull
Yeast counts for the best sample can validate that the bulk of the yeast has been removed.
The recommendation for dose rates to optimise to are as follows:
Super F Dosage (pints per barrel)
Trial Dose ml/500ml
When using Super F we always recommend that you optimise regularly. For the majority we’ve found the best results to be between 0-5°C and when the product is used in conjunction with optimised auxiliary finings and carrageenan use. Last but not least, your yeast count should be 1-8 millioncells/ml of viable yeast.
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 ).
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.
