To test how our products could enhance brewing efficiencies, whilst saving CO2 and money, we partnered with Chris Lewington from Brew Resourceful to conduct trials at London Brewing Company.
Here’s a snapshot of the trial and the benefits gained for the brewery, all without any capital expenditure or changes to overall product quality.
1. Results from Super F Finings
- Increased Yield: By using Super F finings during conditioning, the number of kegs produced per kegging run increased by 5%. This resulted in three additional kegs per run.
- Reduced Carbon Intensity: This boost in yield was achieved without requiring extra resources, thus reducing the carbon footprint of the products.
- Shortened Residency Time: Super F finings also reduced residency time by 2 days, freeing up capacity more quickly and lowering tank cooling costs by 3%.
These quick wins demonstrate how Murphy’s products can make your brewing process more efficient and environmentally friendly.
- Trizyme
- As a product that has been around for a number of years, the benefit of Trizyme is often underestimated with the enzyme often being used as a trouble shooter. However, this blend of α-amylase, β -glucanases and proteolytic enzyme can often offer a boost to extract and mashing efficiency.
Trizyme Data from London Brewing Company
| Without Trizyme | With Trizyme | Savings (£) | Savings CO2E (%) | |
| Brews p/a | 150 | 150 | 0 | |
| KG of Malt per brew | 202.5 | 194 | 9 | 4.30% |
| Cost of Malt P/A | £36,450.00 | £34,887.00 | £1,563.00 | |
| Cost of Trizyme PA | £624.00 | |||
| Net Costs | £36,450.00 | £35,511.00 | £939.00 | 3% |
| kgCO2e malt | 23389 | 22386 | 1003 | |
| kgCO2e Transport | 756 | 724 | 32 | |
| kg CO2e total | 24145 | 23110 | 1036 | 4.30% |
As shown in the data above, the use of Trizyme generated a 3% saving on malt bill. Combined with the cost of the enzyme itself, this offered the brewery a £939 saving on costs through the year – to offset the equivalent amount of CO2 would require the planting of 49 trees.
- ALDC (Alpha Acetolactate Decarboxylase)
- Murphys has been a supplier of ALDC since the 1990’s and its use has been widespread reducing diacetyl and warding off dry- hop creep. On a savings front, the main boost of ALDC is the beneficial reduction in maturation time, reducing energy costs and freeing up tank capacity.
With the use of ALDC, the tank residency time was reduced by 15% with associated electricity costs reduced by 9%. Based on 75 fermentations per year, this offered the brewery a potential capacity increase of 17% which could amount to £91,606 worth of extra sales generated.
Completing the trio of enzymes, we also took a close look at Brewers Clarity. This selective endopeptidase targets proline rich proteins preventing the formation of hydrogen bonds with polyphenols. The net result of this is the streamlining of maturation and downstream processing increasing capacity and reducing tank residency time. In the closer examination of the performance of this product, tank residency per fermentation was reduced by half a day on a typical fermentation. The knock on gain for the brewer was a 2% increase in annual fermentation capacity with the opportunity to gain up to £11,000 in extra sales revenue.
Thanks to Brew Resourceful, we have proven how using additions as little as 3g per hl can really make a huge difference to the efficiency and profitability of a small brewery. In this instance alone potential sales revenue from added capacity was increased by over £100k with a 3% boost on raw material expenditure and real costs savings on fermentation refrigeration energy.
