🧼 Sanitising and Cleaning Equipment for Home Brewing
THE most important aspect of home brewing is sanitisation and cleanliness. Even a small amount of bacteria, wild yeast, or residue can spoil a batch of wine, beer, cider, mead, or other fermented beverages. Proper cleaning and sanitising equipment ensures your brew remains safe, tastes as intended, and has a long shelf life. Remember cleaning and sanitising are two different steps. Cleaning removes dirt and debris that can harbour, cover (protect from steriliser contact!) or encourage bacteria and unwanted yeasts to grow. So clean all equipment first. Only once your equipment is clean, can you sanitise.
💧 Why Sanitising Matters
Fermentation is a controlled process where specific yeasts convert sugars into alcohol. Contaminants such as wild yeast, bacteria, or mould can outcompete your brewing yeast, producing off-flavours, cloudiness, or even complete spoilage. Sanitising your equipment before and after every batch is essential for consistent results.
🧴 Types of Sanitising Equipment
There are several tools and solutions commonly used in home brewing:
- No-rinse sanitisers – Ready-to-use sanitiser powders or liquids dissolve in water and require no rinsing. Ideal for fermenters, siphon tubes, spoons, and bottles.
- Bleach solutions (unscented only!) – Effective if diluted correctly, but scented bleach must never be used as fragrances and additives can spoil your batch. Proper rinsing is required.
- Steriliser powders & baby bottle sterilisers – Purpose-made steriliser powders or baby bottle sterilising solutions, like Milton tablets or liquids, work well for bottles, racking canes, and smaller tools.
Equipment should be fully submerged when possible. For larger fermenters, spray or wipe-down sanitiser solutions are effective.
🧹 Cleaning Before Sanitising
Sanitising is not a replacement for proper cleaning. All equipment should be free from visible dirt, dried yeast, or residues before applying a sanitiser. Use a brush, cloth, or soak in warm water to remove physical debris first. Once clean, sanitiser can kill remaining microbes and ensure a sterile surface for brewing.
🥄 Which Tools Need Sanitising?
- Fermenting buckets and demijohns
- Airlocks and bungs
- Siphon tubes and racking canes
- Stirring and mixing tools
- Bottles, caps, corks, and corking/capping tools
Even small pieces like rubber gaskets on swing-top bottles or lids on buckets need sanitising to prevent contamination.
⚠ Tips for Effective Sanitisation
- Follow manufacturer instructions – Concentration and soaking time matters.
- Use fresh solution – Sanitiser effectiveness declines over time.
- Avoid cross-contamination – Don’t use the same cloth or brush for clean and dirty equipment.
- Temperature matters – Warm water generally improves the effectiveness of most sanitisers.
💡 Budget Options
If you’re starting on a tight budget:
- Unscented bleach can be used safely, provided it’s diluted correctly and thoroughly rinsed. Never use scented or fragranced bleach.
- Baby bottle sterilisers, such as Milton tablets or liquid, are a convenient and safe alternative. They’re widely available, designed for food contact, and perfectly suitable for small bottles, utensils, and tools.
However, for convenience, reliability, and safety, a purpose-made no-rinse sanitiser remains the most dependable choice.
🧽 Cleaning Equipment
Alongside sanitisers, cleaning tools are essential:
- Bottle brushes for narrow-necked demijohns or fermenters
- Siphon tube brushes
- Sponges or cloths dedicated to brewing
- Steriliser buckets for soaking small parts
Regular replacement of brushes and sponges is necessary to prevent them from harbouring bacteria themselves.
