Cleaning and sanitising
Everything that touches the wort before the boil has to be clean. Whatever touches the chilled wort and the beer also has to be sanitised.
What you need
- A cleaner without fragrance, for example sodium percarbonate or a brewery cleaner
- A no-rinse sanitiser, for example based on peracetic acid or phosphoric acid
- A spray bottle
- Soft brushes and sponges, nothing abrasive
Step by step
Step 1Rinse right after use
Rinse the kettle, fermenter and hoses straight after use. Dried-on residue is very hard to remove.
Step 2Clean thoroughly
Soak dirty parts in a warm cleaning solution and remove deposits with a soft sponge. Scratches give germs places to hide.
Step 3Rinse clean
Rinse off the cleaner completely with clear water. Residue harms the head on your beer.
Step 4Sanitise just before use
Sanitise everything that touches wort or beer after the boil: fermenter, lid, airlock, hoses, spoon, thermometer and bottles. Keep to the contact time stated by the manufacturer.
Step 5Don’t touch
Don’t touch the inside of sanitised parts with bare hands and don’t dry them.
Step 6Look after your bottles
Rinse bottles as soon as you have poured the beer. Then cleaning and sanitising is all they need before the next bottling.
Tips and common mistakes
- Cleaning comes before sanitising: no sanitiser works under dirt.
- Be careful with chlorine: residue can cause medicinal off-flavours.
- Gear used only before the boil has to be clean but not sanitised. The boil sterilises the wort anyway.
