Quick Guide to Cellar Hygiene: Keep Your Beer Fresh & Your Business Thriving

A well-maintained cellar is the heart of any pub, brewery, or hospitality venue. It’s where quality is preserved, flavours are protected, and customer satisfaction begins. Yet, cellar hygiene is often overlooked, leading to avoidable issues like tainted beer, waste, and costly reputational damage.

In this short guide, we’ll explore why cellar hygiene is non-negotiable, the most common mistakes businesses make, and how to streamline your cleaning process with the latest technology.

 Why Cellar Hygiene Matters More Than You Think

Cellars are the unseen backbone of beer service. When poorly maintained, they can become breeding grounds for yeasts, moulds and bacteria, all of which can wreak havoc on your beer’s taste and quality.

Even small lapses in cleaning can lead to:

• Off-flavours and contamination – affecting your beer’s freshness and consistency.
• Increased waste – leading to unnecessary financial losses.
• Health & safety risks – a dirty cellar can harbour bacteria that are harmful to staff and customers.
• Damaged equipment – residue buildup can shorten the lifespan of taps, kegs, and lines.

The Cost of Poor Cellar Hygiene

Did you know that improper cleaning can cost operators almost £32,000 per year!¹ Beyond just the financial losses, a bad pint can drive customers away, leading to poor online reviews and a damaged reputation. Investing in proper hygiene isn’t just a necessity it becomes a critical business move.

 Common Cellar Hygiene Mistakes (And How to Avoid Them)

Many venues may follow outdated cleaning methods or overlook key hygiene practices. Here are some of the most common mistakes:

 1. Using the Wrong Cleaning Products

Not all cleaning solutions are designed for food and beverage environments. Many can leave behind residue, require rinsing, or contain harsh chemicals that can affect beer quality. Using a fragrance-free, residue-free cleaner & sanitiser ensures your equipment is properly cleaned without contamination risks.

2. Ignoring Keg & Cask Equipment

It’s easy to focus on beer lines while forgetting about the kegs, couplers, and connectors. But these areas are just as crucial. Regularly sanitising keg and cask equipment helps prevent bacteria buildup that could impact every pour – making cellar hygiene a critical area of consideration.

3. Letting Rubbish Build Up

Old beer spills, damp floors, and neglected surfaces create the perfect environment for bacteria. A clean cellar isn’t just about the beer - it’s about the entire space, from floors to ceilings.

4. Skipping Routine Cleaning

Cellar hygiene and cleaning shouldn’t be only an occasional deep clean - it needs to be a consistent part of your routine.  Using quick and easy products that are shown to work can help make daily maintenance easier and more efficient.

The Science Behind Beer Spoilage and Hygiene ²

The good news is that beer, due to its high ethanol content, generally speaking, creates an unfriendly environment for microorganisms to grow.  The bad news is that despite this, some bacteria and wild yeasts have now adapted and can contaminate beer. Even microscopic residues can create unwanted flavours and aromas. Some of the most common beer-spoiling culprits include:

• Lactobacillus, Pediococcus, Brettanomyces and Enterobacteriaceae.

Proper cleaning, with a product designed to tackle these organisms is key to ensuring that the pint tastes as the brewer intended.
