Tuesday, October 24, 2023
Embarking on a homebrewing journey and in search of the finest sanitizers to ensure the best brew? 

You're in the right place.

We know a thing or three about sanitizer.

The essence of a flavorful beer lies not just in the ingredients but also in the cleanliness and sanitation of your equipment. Any seasoned homebrewer will emphasize the importance of immaculate equipment and bottles to ward off any undesirable bacteria that might ruin your concoction.

Recall a time when your brew was compromised due to insufficient cleaning? You beer was wrecked as it was infected?

It's an agonizing experience, isn't it?

You spend the time and money on malt, yeast and hops and then it's simply undrinkable acid. 

Want no fuss, just need the good stuff? The good oil on sanitizer? Regardez-vous:




Star San

Highly Effective: Rapidly kills microbes and does not require rinsing, leaving behind a foam that can benefit yeast health. Non-Toxic: Made from food-grade phosphoric acid which is safe for use. Ease of Use: Only requires contact for 30 seconds to be effective.

Foam Production: Produces substantial foam which can be mistaken for residue or contamination by new brewers. Sensitive to Environment: Less effective in hard water or when improperly diluted.


No-Rinse: At proper dilutions, it does not require rinsing and leaves minimal residual taste or odor. Indicator: Changes color to indicate effectiveness and proper dilution. Broad Spectrum: Effective against a wide range of organisms.

Staining: Can stain plastics and fabrics with prolonged contact. Short Shelf Life: Once diluted, it loses potency within 24-48 hours. Sensitive to Light: Degraded by light exposure, requiring storage in dark containers.

One Step

No Rinse Required: Easy to use without the need for rinsing, making it quick and convenient. Environmentally Friendly: Oxygen-based and biodegradable. Safe: Non-toxic formula makes it a safer choice for home brewers.

Less Effective on Hard Surfaces: May not be as effective as other sanitizers on hard, non-porous surfaces. Requires Longer Contact Time: Generally needs at least 2 minutes to sanitize effectively.


Highly Affordable: Widely available and cost-effective. Powerful Disinfectant: Extremely effective at killing a wide range of microbes. Versatility: Can be used for various cleaning tasks beyond brewing.

Corrosive: Can damage stainless steel and other surfaces if not thoroughly rinsed. Residual Smell: Leaves a strong chlorine odor that must be completely rinsed to avoid flavor impact. Rinsing Required: Must be thoroughly rinsed to prevent contamination.

Powder Brewery Wash

Effective Cleaner: Excellently removes organic residues like proteins and lipids. Versatile: Safe on all materials including stainless steel and plastic. Environmentally Friendly: Biodegradable and non-hazardous under typical use conditions.Requires Thorough Rinsing: Must be completely rinsed off to prevent interaction with sanitizers. Not a Sanitizer: Only cleans, does not sanitize—sanitization step is still necessary. Optimal Performance Requires Hot Water: More effective with warm to hot water, increasing energy usage.

Let's dive in and explore the top sanitizers that will shield your beer, cider, or wine from any brewing adversaries.

1. Star San: The Pinnacle of Sanitizers

Star San is renowned for its formidable ability to annihilate any microorganisms threatening your brew. Characterized by its makers as "a self-foaming acid sanitizer apt for brewing, dairy, and other edibles," it stands out as a potent bactericide and fungicide. 

What's more, it's resilient against excessive organic soils and diminishes water spotting. Comprising phosphoric acid and dodecylbenzenesulfonic acid, Star San is a no-rinse solution — a significant advantage for brewers eager to get brewing.

Usage: Star San can be applied through spraying or soaking equipment and bottles. A ratio of one ounce to 5 gallons of water ensures optimal protection against bacteria.

However, its superiority comes with a premium price tag.

2. Iodophor: The Trusted Choice

Iodophor, favored by the beer brewing community, has roots in the food service and medical sectors for equipment sanitation. A trifecta of detergent, germicide, and sanitizer, Iodophor promises sanitation in approximately 10 minutes. As with Star San, it requires no rinsing at the suggested concentration.

A word of caution: Iodophor can stain clothing, so exercise care during use.

3. Powdered Brewery Wash (PBW)

Originally embraced by commercial breweries, PBW has won the hearts of homebrewers for its sanitizing prowess. Many veteran brewers laud its effectiveness. PBW not only sanitizes but also aids in removing beer labels from bottles.

A tip: You can craft your own PBW alternative using household products. Blend a home brand like Tide or Oxiclean with a metasilicate-rich cleaner like Red Devil TSP/90 in a 70/30 mix to craft a DIY sanitizer.


4. Laundry Soakers: The Unexpected Savior

Surprisingly, common laundry soakers can serve as sanitizers. Products boasting 'oxy' labels typically contain sodium percarbonate, a chief ingredient in many renowned soakers. We can personally testify that this is the key product we use to prepare our beer bottles and brewing drum - it's cheap an effective. 

5. Bleach: The Old Reliable

Bleach, while commonplace, can be a potent sanitizer for homebrewing. A solution of 1 tablespoon of bleach to 1 gallon of water, followed by a 20-minute soak, should suffice. However, due to its strong odor, rinsing is advised. For quick results, opting for faster-acting solutions like Star San might be more prudent.
