From a sudden Friday crisis to smooth weekend operations: How the brewery ensured hygiene and production
As a brewmaster or production manager, your focus should be on the craft and flavor profiles, not on leaky connections or contaminated batches. Yet worn-out hoses often pose a direct risk to both beverage quality and production time. Finding a reliable food-grade hose for breweries is crucial to avoiding disasters. This became painfully clear when a microbrewery faced an emergency production shutdown one Friday afternoon.
Thanks to efficient processing at our own Swedish workshop, we at Colly Flowtech were able to assemble, test, and deliver a certified food-grade hose for breweries in butyl rubber that same day. Here’s how an urgent crisis was turned into long-term operational reliability.
The Challenge: Streamlined Production with Rigid Hoses
In a small brewery, margins are tight. Strict hygiene requirements must be balanced with a fully booked brewing schedule, while deliveries to restaurants and retailers must leave the facility on time. In such an environment, a production stoppage quickly becomes a costly affair.
For the customer in this case, daily operations were marked by concerns about leaks during transfers between tanks. The existing hoses had become stiff and hard after repeated CIP (Clean-in-Place) cleanings. To keep production running, the company had relied on temporary solutions using simple hose clamps.
This created three critical risks:
- Serious hygiene risks: The hose clamps created hard-to-clean areas where bacteria could thrive, threatening the quality and taste of the beer.
- No traceability: The hoses lacked labeling and documentation in preparation for upcoming food safety audits.
- Poor working conditions: Staff were forced to constantly monitor the process during pumping due to the risk of leaks and slip-and-fall accidents.
The final straw came one Friday afternoon when a sudden pipe burst threatened the weekend’s production. Failure to act posed an immediate risk of having to scrap the entire batch of finished beer, missed deliveries, and costly express shipments of replacement materials from abroad.
The Solution: Certified Food-Grade Hose for Breweries and Machine-Pressed Fittings
Finding the right equipment for sensitive beverage applications is all about meeting extremely stringent technical requirements. A modern food-grade hose for breweries must withstand dramatic temperature fluctuations—from ice-cold liquids to hot chemical cleaning—without imparting any odor or taste. In addition, the materials must be food-grade in accordance with FDA and EU regulations.
The tight spaces around the tanks required custom lengths to prevent kinks and broken hoses, while the connections on the machinery varied greatly. The brewery lacked both the time and the tools to solve this on its own under time pressure.
We at Colly Flowtech developed a long-term, comprehensive solution based on the customer’s unique processes:
- Butyl rubber for product safety: We chose a flexible food-grade hose for breweries made of high-quality butyl rubber. The material ensures that the beer’s taste and aroma remain completely unaffected, while also withstanding rigorous cleaning without cracking.
- Independent validation: The hose has been approved by the well-known German institute Technische Universität München Weihenstephan, which provides the customer with a written guarantee of the material's suitability.
- Machine-pressed sanitary couplings: We replaced the unreliable hose clamps with completely smooth, machine-pressed stainless steel couplings to eliminate all bacterial traps.
Thanks to our in-house workshop in Sweden, we were able to reduce lead times and offer greater flexibility. We manufactured the hoses to exact lengths, crimped the fittings, and pressure-tested each unit before delivery. Each food-grade hose for the brewery was labeled to ensure full traceability of all components and was delivered that same afternoon along with a corresponding pressure test and material certificate. The customer was able to install the hoses immediately and run weekend production without any interruptions.
The Result: Operational Reliability and a Peaceful Work Environment
Since the transition to our certified system, the brewery’s production has been streamlined, both on the production floor and in administrative processes. The measurable results speak for themselves:
- No leaks or unplanned downtime during the first few months after installation.
- Significantly faster hose changes thanks to standardized couplings.
- Longer equipment lifespan, which reduces maintenance costs over time.
- Full traceability linked to material certificates, providing greater peace of mind.
The long-term benefits, however, extend beyond the numbers. The brewmaster has regained a sense of calm at work and no longer feels stressed about weekends and peak season. The work environment at
The floor is now both dry and safe, and thanks to the clear labeling, management is looking forward to the next food inspection with great confidence. The hoses are no longer viewed as a cheap consumable, but rather as a critical investment in the brewery’s process safety.
Is your facility ready for the next food safety audit?
Take control of your workflow before it becomes a crisis. As a production or quality manager, you should conduct a quick self-assessment of your operations today:
- Do your hoses show signs of stiffness, cracks, or discoloration?
- Are you still using makeshift solutions or simple hose clamps that harbor bacteria?
- Are your hoses labeled, and do you have the proper certificates on hand for the next inspection?
- How much would it cost your business if production came to a complete standstill next Friday afternoon?

Explore our range of food hosesFrequently Asked Questions About Food-Grade Hoses for Breweries
What is the best material for a beer and brewery hose?
Butyl rubber (EPDM) and specially treated rubber are the best materials because they are completely tasteless and odorless. They are also durable enough to withstand both high temperatures and the heavy mechanical stresses found in a brewery.
What does it mean for a hose to be food-grade?
This means that the hose’s material meets strict international requirements, such as those of the FDA (U.S.) and EU Regulation 1935/2004. This certification ensures that the hose does not leach harmful chemicals, flavors, or odors into the beverage.
How often should a food-grade hose be replaced in a brewery?
It depends on usage, but hoses should be inspected regularly and replaced as soon as the inside shows signs of cracks, stiffness, or discoloration. Worn hoses quickly become a hygiene risk, as bacteria can begin to grow in the material’s microcracks.
Can you use the same hose for both hot wort and cold beer?
Yes, provided you choose a high-quality brewing hose that is rated for that wide temperature range. The hose must be able to expand and contract without the material cracking or losing its pressure capacity.
What is the difference between a standard suction hose and a pressure hose in a brewery setting?
A suction hose has an embedded steel or plastic spiral that prevents the hose from collapsing under negative pressure (vacuum) when, for example, pumping from a tank. A pure pressure hose lacks this spiral and is instead optimized to withstand high internal pressures without expanding.
