I use a 10-gallon Igloo beverage cooler with a Coldbreak false bottom, Blichmann Auto-sparge, and home-made 240V RIMS and I can't think of anything I'd rather have.  Not shiny, but does everything I need.

All Grain Brewing / Re: Brun Water Question for Pale Ale profile

Phosphoric acid is considered more flavor-neutral.  At the typical 10-15% concentration available at shops you have to add a lot more of it than lactic.

My homebrew club does an "Iron Brewer" comp every year with ingredients drawn from a hat.  The first year was a kiwi-agave beer.  Those were so dreadful we now have veto power over proposed ingredients.  My kiwi-agave beer was extremely tart in an unpleasant way and the kiwi seeds were impossible to filter out.  I hung onto it for about a year hoping it would improve, but ultimately dumped it.

I use Brewpi software for my fermentation chamber employing a raspberry pi, arduino, and relays. It has network connectivity and you can add a wi-fi module to the pi.  That concept could be employed for the hot side.  In fact the brewpi developers are into that now with spark.

You don't need to add yeast. When I used to bottle, I had success with lagers that had been at 33F for 6 weeks.  There's always yeast in solution if you haven't filtered.  You can add yeast if you're scared; it won't hurt.

This is what I use. Not as fancy as the one posted above. I got like a 20-pack of the CO2 cartridges which I consider a lifetime supply.

Used to use a hop spider, but whirlpooling Is a better solution.

Kegging and Bottling / Re: Purge keg with Iodophor
« on: July 20, 2017, 08:15:41 AM »
Iodophor is great for kegs. After purging, if you can give the keg an hour or so for all the liquid to sheet down the sides just depress the liquid poppet and let the last of the iodophor spray up your arm.  What's left doesn't effect the lightest pilsner or wheat beer.

Equipment and Software / Re: Using upright freezer for fermenter

Some upright freezers have refrigeration coils attached to the shelves, rendering them useless for our purposes. I know from experience.

  As for the hydrometers, I'm not aware of any way to calibrate them.
Put each hydrometer in 60F water and see how far it deviates from 1.000. I usually find them reading high from the paper inside sliding down. Then I wrap tape around the top until it reads 1.000.

Life's too short to drink bad beer.

If fermentation is generating heat uniformly throughout and you are withdrawing heat from the surface, temperature in the center has to be higher. That's science.

Does it make a difference? I've never noticed.  I was just pointing out that neither the probe on the side or the one in the center gives you a uniform temperature throughout.

Well, the reverse is true with the probe on the side. The center of the fermenter is at a higher temperature during fermentation.  So you either get an unknown higher temp or an unknown lower temp where your probe isn't.

I use a 10-gallon Igloo mash tun.  I can do 10-gallon batches of beers of 1.055 or less.  When going for something bigger, I just add a pound or two of extract to the kettle.

Those heat wraps might struggle with a 20 degree lower ambient.  I'd wrap insulation around the outside of the heat wrap.  I ferment lagers in my garage in the winter with the heat wrap and insulation.  The water in the dog's bowl would freeze, but the beer hangs in there at 50 F.
