Don’t Skip This Step: Cleaning & Sanitizing in Home Winemaking

Let’s be real, cleaning and sanitizing aren’t the most exciting parts of making wine at home. But if you skip this step? You might end up with a funky-smelling, spoiled batch after weeks of waiting.

I’ve definitely made that mistake before, and let me tell you, it’s not worth it. This post breaks down why cleaning matters, what you actually need to sanitize, and how to make it all simple and stress-free.

• Cleaning removes dirt, fruit residue, pulp, or sugar. Anything sticky or visible.

• Sanitizing kills the invisible stuff like bacteria, mold, and wild yeast that could ruin your wine.

• You could get a spoiled batch that smells bad or tastes off

• Cloudy wine or fizz when you didn’t plan for carbonation

• Worse…your wine could grow mold or start to rot

I’ve had it happen. It’s not cute. Sanitize and save yourself the heartbreak.

• Fermentation jugs, buckets, bottles

• Funnels, spoons, strainers

• Airlocks, rubber bungs

• Your hands and your work surfaces

Even if something looks clean, it can still carry bacteria that mess with fermentation.
And yes, even brand-new equipment should be cleaned and sanitized before using it.

• Star San: My go-to. It’s no-rinse and very effective.

• Campden tablet solution: Can be used to sanitize equipment in a pinch.

• Boiling water: Good for small heat-safe items.

• Diluted bleach solution: Works, but you MUST rinse thoroughly.

Choose what works best for your setup. I usually keep Star San in a spray bottle for quick use.

When I’m prepping for a wine day, I sanitize everything first. Jugs, spoons, strainers—anything that’s going to touch the wine.

I use a Star San spray bottle, and I lay everything out to air dry on a clean towel. It takes 10–15 minutes but saves me weeks of frustration.

• Keep a spray bottle of sanitizer nearby while working

• Label sanitized gear so you don’t double-clean

• Sanitize again before bottling, even if it’s been sitting clean for a while

Cleaning and sanitizing might not be glamorous, but it’s the secret to wine you’ll actually enjoy drinking.
