I don't know what your source is telling you, but most of the sanitizers are Iodine based. Bleach is bad news, as it will attack stainless steel.

And oh, I keep thinking about it - having gotten Williams brewing catalogs since the mid 90s. The deterent here is that space is at a premium, I currently have other things that come first, and good beer is as far as the closest bodega.

Still, words like Conical fermenters and 3 tiers occasionally pass my lips. :D

In a somewhat related vein (it's about alcohol,) what's involved in distilling, say, rum?

The turkey frying kits they sell this time of year are a good source of propane burners for home brewing. Do not use the aluminum pot they usually come with though. It will mess with the chemistry of the wort and won't hold up to the required cleaning. Everything that comes in contact with beer must be either stainless steel, copper, glass, or food grade plastic. In fact, IIRC, trace ammounts of copper are required for good fermentation. A porcelin enamel stock pot is acceptable as long as it's not chipped.
If you don't want to bottle your beer; you can get a kegging rig for about $85 including your first keg. Once you're used to it, kegging generally works out better actually, and is less work; though it's more complicated.
Cornelius Kegs are excellent for this purpose. Also, if you use a keg you don't need to carbonate the beer through fermentation. You transfer the beer into a keg, seal it, and refrigerate it. Under refrigeration, pressurize the beer with CO2 to about 15 psi and keep it under pressure until it reaches the desired level of carbonation, (usually 1 or 2 days). This is how most commercial breweries do it.

I don't know much about distilling rum except that it's made from fermented [strike]molasses[/strike] sugar cane. Also, distilling for human consumption is illegal in the US unless one posesses the proper licenses and pays the taxes. There are exceptions for those who distill alcohol for fuel purposes. ;)

The bacteria also multiplies at a faster rate then the yeast IIRC which makes it even more fun. It's also why I double up on the slap packs.

Actually, I did know a couple of the SENT guys who would pick up brewing kits from Boots Chemists everytime they went to Moldyhole, and sometimes made some really decent beer (if you allow for the occasional exploding bottle under the stairs).

I didn't do the SENT missions; started with the APPLE at the tailend of the SEA Wargames, and worked WIND mission in the SOJ/Korea orbits.

I know -- corrosion's a PITA** -- Many dairy guys actually run both* -- bleach isn't as corrosive if you keep the concentration at the proper level.

*Including us. That's actually why I've been intrigued by the Cl gas sterilization -- it doesn't leave any residue to flavor the product, and it's shouldn't corrode -- it's very small amounts of gas, which is supposed to remain in solution. I don't want to give up using Cl- in addition to I- as sterilizing agents.

**Polishing stainless is one of the "make work" jobs we have, which is never completely finished.

Of course, if we get the Cl gas wrong, not only have we probably killed someone, but it will corrode like mad...

It sounds like y'all are talking about chlorine dioxide generated by an activated sodium chlorite solution. I hadn't heard about this before, since I've been out of the industry for over ten years, but it sounds reasonable. I found the following article with a little G-fu:
A post-rinse sanitizer which is not iodine based has started gaining acceptance with craft brewers. Chlorine dioxide (ClO2), like iodophor, is very effective at destroying spore forming organisms at low active parts per million (ppm) levels and does not flavor beer when used properly. Unlike iodophor, however, the amount used is typically not as critical both in terms of microbial reduction and flavoring beer. In other words, you will still get an effective kill at an active level of 50-100 ppm ClO2 while maintaining a minimal or non-existent flavor profile.

Advantage-
Remember: Sodium Chlorite is not Sodium Hypochlorite!

Mention the words "chlorine" and "sanitizing" in the same breath around most brewers and their response is, normally, "It will flavor my beer." (This usually comes from the same person who taints his / her brew with iodophor). In the case of sodium hypochlorite bleach, they are correct. As little as 1-2 ppm active hypochlorite is detectable in drinking water. Triple rinsing is necessary to remove bleach from brewing equipment and bottles so as not to flavor the beer with chlorine. Therefore, post-rinse sanitizing equipment and bottles is not recommended with hypochlorite bleach.
