If you have poor connections in your electronics or something similar, you might have considerable variations in the system responses. The physics of the sensors and the electronics is about as well understood and consistent as the cosmos allows (background limited). The semiconductor doping...

Thanks bottlebomber (I hope your title handle ISN'T based on repeated experience with explosions...:) That is the basis for my thinking. There has to be some other impact to the brew other than color, but narrowing down the most natural ingredient to get to a medium color with the least impact...

hercher is likely to be answering this in a nice succinct way, and I realize that. The right bit of caramel/crystal seems to make sense based on kilning/malting basics. But, there are all these other ingredients just begging to be tried. Calling out to be part of a beer. I haven't given...

Thanks bottlebomber. I was looking at that and other similar grains trying to decide what to buy. I'm in a fairly remote area and UPS works better than a trip to the LHBS. This is what drove me to the question. Have you used this grain for getting color, mostly...? Don't' get me...

Is that as effective as something like "cararoma" or "carastan, caravienne, etc...?" I have used crystal of various levels for years, but I've never tried those other grains. I'm perfectly pleased with crystals, but I was wondering if that's the most straightforward way to get to "red." I...

Hello All, I'd like to make a medium strong ale, say 6% ABV. I don't care about the "style" specifically, but I want to limit the effects of "roast, patent, caramel, chocolate etc." What is the best specialty grain to get a red color without adding the associated flavor effects? IOW...

Temp sensors, working over the range of freezing to boiling water, are really pretty linear. Thermocouples, temp sense diodes, RTD's, Hg thermometers, all are linear to any measurement any of us are doing (Brewing anyway. In my labs it gets a bit trickier.) The linearity is in the measurement...

Not totally true. The aluminum is not ferrous or "magnetic" true. However, aluminum is conductive. The spinning magnets will induce electric currents which will interact with the magnetic fields, and so on, and so forth. Ever seen a sensitive mechanical balance (scale)? Often there will...

You're doing the right thing in the "research" and "reading" part. Try and keep in mind the things you're attempting to accomplish. Getting wort. I once was about to throw out an old laundry sink. I converted that puppy into a great mash/lauter tun with a bit of screen, a valve on the...

Thanks grndslm. I sincerely appreciate the comments. Don't get me wrong, I've gotten nice compliments with bottled beer as well. I've never entered any contests, but something worked ok. If you can add a bit of temp control, cool! See what you think about the impact. I'd be interested...

Going strictly by comments made by friends/family on my results: Most impact to least impact: 1) Going from bottling to kegging/force carbonation. 2) Controlling fermentation temps (from water baths, etc. to controlled fridge). 3) Pitching the right amount of yeast (from smack...

Perfect info! I have always been a little concerned about the "air drying" with iodophor and rinsing chlorine seems to be sorta defeating the purpose. That's a good example of a procedure that takes some of the W out of RDWHAHB! Thanks!

Excellent! Exactly my question. thanks much for the reply. That makes sense, with your input. I needed to consider the ph in working through the thought process. I've always been a chlorine/iodine user, but I'm going to order some Star San and begin using it. This is a great source...

Hello All, From reading the posts of many experienced brewers, it seems Star San is fairly compatible with our friends, the yeasties. Some comments even suggest that the compound, in certain situations, can become a yeast nutrient. Can anyone comment on the toxicity of Star San to yeast...

As an experimental physicist, I can justifiably state, that is the above is NOT a true statement. An experiment ends in results which are useful no matter what the outcome. It, in no way suggests a procedure be followed. It provides insight into the system response to controlled conditions...
