How to Sanitize a Carboy? Help Support Homebrew Talk:. We all hear it - "sanitize everything that comes into contact with cooled wort. Or a 7 gal bucket? The mixing rate is 1 Tbl. OneStep, et al, are working at similar rates. So - here's the rub He actually says that rinsing isn't required at that ratio!
FlyGuy Well-Known Member. For sanitizing carboys, the easiest thing to do is get a sanitizer the requires low contact time, such as Star San or Iodophor. They only need to be in contact for about a minute or two to be effective. This way, you can put a quart or two of sanitizer in your CLEAN carboy, put on a stopper, and then swish the sanitizer around to sterilize the whole inside.
You could also use your bleach solution very effective but it requires a much longer contact time, meaning that you would have to fill the whole carboy up and let it sit for a while.
Works just as well, but it is a PITA. OneStep requires a few more minutes of contact time, so it takes several 'shakings' to really sanitize properly with a gal solution. Well, in actuality, the bleach solution only requires 30 seconds, according to Charley Talley and he invented StarSan, so I trust him. The BrewVint only requires 30 seconds, as well.
So what I'm hearing is that swishing around just a couple of quarts is going to do the job? I suse StarSan, used to use bleach. Approach was the same. If I was making a bunch of sanitizer, I'd fill teh carboy with it, let it soak for awhile, then siphon the sanitizer into a RubberMaid tub for other uses. If I just want to sanitize a carboy, I'll mix up a half-gallon and slosh it around in the carboy. Let sit a minute or two, repeat a couple times. Seems to work fine for me.
The star San foam is enough to sanitize. I only get the carboy about half full of water and there is foam shooting out the top. You can save Star San for several weeks after mixing.
Beerrific Well-Known Member. Key is, as it was said before, clean after use and all you have to do on brew day is sanitize. Idophor or Starsan in a spray bottle, sprayed into the neck of a carboy laying on the floor and rotated works well for me.
The viability of the solution can be judged by its clarity; it turns cloudy as the viability diminishes. One last note on this product: Because it is listed as a sanitizer and bactricide by the FDA and EPA, the container must list disposal warnings that are suitable for pesticides.
Do not be alarmed, it is less hazardous to your skin than bleach. Iodophor Iodophor is a solution of iodine complexed with a polymer carrier that is very convenient to use. One tablespoon in 5 gallons of water 15ml in 19 l is all that is needed to sanitize equipment with a two minute soak time.
This produces a concentration of Soaking equipment longer, for 10 minutes, at the same concentration will disinfect surfaces to hospital standards. At If the solution loses its color, it no longer contains enough free iodine to work.
There is no advantage to using more than the specified amount of iodophor. In addition to wasting the product, you risk exposing yourself and your beer to excessive amounts of iodine.
Iodophor will stain plastic with long exposures, but that is only a cosmetic problem. The Even though the recommended concentration is well below the taste threshold, I rinse everything with a little bit of cooled boiled water to avoid any chance of off-flavors, but that's me.
Heat Heat is one of the few means by which the homebrewer can actually sterilize an item. Why would you need to sterilize an item? Homebrewers that grow and maintain their own yeast cultures want to sterilize their growth media to assure against contamination. When a microorganism is heated at a high enough temperature for a long enough time it is killed.
Both dry heat oven and steam autoclave, pressure cooker or dishwasher can be used for sanitizing. Oven Dry heat is less effective than steam for sanitizing and sterilizing, but many brewers use it. The best place to do dry heat sterilization is in your oven. To sterilize an item, refer to the following table for temperatures and times required. The times indicated begin when the item has reached the indicated temperature.
Although the durations seem long, remember this process kills all microorganisms, not just most as in sanitizing. To be sterilized, items need to be heat-proof at the given temperatures. Glass and metal items are prime candidates for heat sterilization. Some homebrewers bake their bottles using this method and thus always have a supply of clean sterile bottles.
The opening of the bottle can be covered with a piece of aluminum foil prior to heating to prevent contamination after cooling and during storage. They will remain sterile indefinitely if kept wrapped. One note of caution: bottles made of soda lime glass are much more susceptible to thermal shock and breakage than those made of borosilicate glass and should be heated and cooled slowly e.
You can assume all beer bottles are made of soda lime glass and that any glassware that says Pyrex or Kimax is made of borosilicate. Autoclaves, Pressure Cookers and Dishwashers Typically when we talk about using steam we are referring to the use of an autoclave or pressure cooker.
These devices use steam under pressure to sterilize items. Because steam conducts heat more efficiently, the cycle time for such devices is much shorter than when using dry heat.
Dishwashers can be used to sanitize, as opposed to sterilize, most of your brewing equipment, you just need to be careful that you don't warp any plastic items.
The steam from the drying cycle will effectively sanitize all surfaces. Bottles and other equipment with narrow openings should be pre-cleaned.

I keep this bowl throughout brew day so that if I accidentally touch a part against something dirty, I can just dunk it in the sanitizing bowl.

However the bottle is huge and super concentrated so it may take a while Glad this is useful. Should say that if you do start using iodine check the concentration of the bottle because it can vary, and in high doses iodine can be toxic. There are concentration test strips you can buy that work just like pH strips. I used those in the beginning of my brewing and can now eyeball the right levels.
I forgot to mention that before using my carboy I lay them on their side and roll them around a bit to make sure the star san solution touches every surface. Thomas Campion Thomas Campion 11 1 1 bronze badge.
