Enhance Brewhouse Efficiency - Muphy & Son
To test how our products could enhance brewing efficiency while saving CO2 and money, we partnered with Chris Lewington from Brew Resourceful to conduct trials at London Brewing Company.
Here’s an overview of the trial and the benefits gained for the brewery, all without any capital expenditure or changes to overall product quality.
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%, resulting 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
Trizyme, a blend of α-amylase, β-glucanases, and proteolytic enzyme, often offers a boost to extract and mashing efficiency, though its benefits are often underestimated.
Trizyme Data from London Brewing Company
| Without Trizyme | With Trizyme | Savings ($) | Savings CO2E (%) | |
|---|---|---|---|---|
| Brews per year | 150 | 150 | 0 | - |
| KG of Malt per brew | 202.5 | 194 | 9 | 4.30% |
| Cost of Malt per Year | $36,450.00 | $34,887.00 | $1,563.00 | - |
| Cost of Trizyme per Year | - | $624.00 | - | - |
| Net Costs | $36,450.00 | $35,511.00 | $939.00 | 3% |
| kgCO2e Malt | 23,389 | 22,386 | 1,003 | - |
| kgCO2e Transport | 756 | 724 | 32 | - |
| kg CO2e Total | 24,145 | 23,110 | 1,036 | 4.30% |
The data shows a 3% savings on the malt bill with Trizyme. 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 planting 49 trees.
ALDC (Alpha Acetolactate Decarboxylase)
Murphy’s has supplied ALDC since the 1990s, widely used to reduce diacetyl and ward off dry-hop creep. The main benefit of ALDC is the reduction in maturation time, which reduces energy costs and frees up tank capacity.
Using ALDC, the tank residency time was reduced by 15%, and associated electricity costs were reduced by 9%. Based on 75 fermentations per year, this offered the brewery a potential capacity increase of 17%, potentially generating $91,606 in extra sales.
Brewers Clarity
Brewers Clarity, a selective endopeptidase, targets proline-rich proteins to prevent the formation of hydrogen bonds with polyphenols. This streamlines maturation and downstream processing, increasing capacity and reducing tank residency time.
In a detailed examination, tank residency per fermentation was reduced by half a day, resulting in 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 demonstrated how using additions as small as 3g per hl can significantly enhance the efficiency and profitability of a small brewery. In this instance, potential sales revenue from added capacity increased by over $100k, with a 3% boost in raw material expenditure and real cost savings on fermentation refrigeration energy.
