What I find irritating is I seriously contemplated buying shares of the company around 2000 at $8 per share, but it was fluctuating so wildly on a daily basis I did not. It's at $226. Where's the facepalm emoticon when you need it.

i wanted to drop a few grand on James Buster Douglas to beat mike tyson in 1989ish, just because he was from ohio.  I thought better of that rationale :P

Jim Koch is an evil 1%er?!   Oh the humanity!!   ::)

What next, Santa's not real?

i have heard that santa has add or dementia.  i mean he does have to keep making a list and check it twice

I would have it sit in the foyer as a decoration in the old Victorian house I don't own  ;D

almost a piece of art.


my buddy used one of my grain bags in  his press to keep the solids from running out. do you do anything like this or just let it go?

so are you assuming that the water in the pot (being cooled) is moving only under natural circulation?

I was a chemical engineer, now a patent attorney.  I have a copy of Perry's where the data they use comes from.  The article is purely a paper study.  Their calculations are reasonably accurate for doing comparisons among common cooling options.  I would not assume that they are accurate for other purposes.    I do not consider what they are doing "BS," but I'm not surprised that one person's real world data does not coincide with an estimate from a paper study.

Theoretically, counterflow cooling should always be faster than batch immersion cooling for same coolant flow rate and same heat transfer area assuming proper design because in counter flow the coolant exiting the cooler is cooling wort at the initial temperature.  In immersion cooling, very little of the coolant is cooling wort at the initial temp.

yes, but you are assuming stagnant flow around the immersion cooler.  if you move the wort around it is similar to a typical bi flow heat exchanger. i would argue that the volumetric flow rate from a paddle moving the wort around the immersion coil is probably on the order of gallons per second as compared to a pump pumping it through a heat exchanger.  similar to how air moves over an engine be it air cooled or liquid cooled.  as long as something is moving air over the fins it will cool faster.

I use one of these...winner of many cider press comps!

that is pretty awesome. my buddy made about 8 gallons of cider this last weekend.  we have not fermented any yet. every one is drinking as is.  he made a chopper out of a brand new high horsepower garbage disposal with a rigged up fan to help keep the motor cool.  worked very well.

Too many theoretical variables. You okay at that

I'm okay with the time it takes to chill. But the study in Zymurgy says they're getting it done in 10 minutes vs. my 14 minutes.
The variables:
They chilled 5 gallons, I did 5.5.

They used a 46'x3/8" coil. I use 2 separately-fed  25'x3/8" coils. Theoretically, this should give mine an advantage, at least enough to make up for the slight difference in volume.

We both used 65f water to chill.

I circulate the wort continuously, in the opposite direction of chiller flow.

My chiller flow rate is 3 gpm. So is theirs.

So how do they chill so much faster? Or do they? Perhaps the article is based strictly on calculations, with no scientific data, and is really just theoretical bs?
It does look like calculations were used for the graph. The data point for the immersion being below the counterflow is counterintuitive. You could e-mail Zymurgy and ask the question there, and I suspect the author would respond. Worked for me a while back when I had a question.

i have not read the full article, but i don't find it counterintuitive.  if they recirculated the wort with a paddle briskly around the immersion coils the heat transfer gradient could be significantly higher, including th e tranfer at the air interface and the wort kettle interface.  in fact, an argument could be made that this is significantly better than that from pumping a laminar layer through a counter flow or even a cross flow heat exchanger.

thanks guys. I like Drew's brewing book so I bet  this is as good and will pick it up

thanks. it will probably be small scale.  he did buy a press. he found some forum where guys make grinders out of garbage disposals. we'll see

  i have only done a few at most. and they were basic, however, one of my colleagues has an orchard and an over abundance of apples.  he wants to try to make his own cider. both alcoholic and not alcoholic.  does anyone have any recommendations on shredding the apples, pressing etc?

Boulevard--Saison Brett

Good luck finding that! It took me two cities worth of looking to get my little stash of 5 bottles going.

All of Boulevard's Smokestack Series is excellent though.

single wide better than double wide IMHO

2.) Edit: My wife informs that DFW may have meant Dallas Fort-Worth, rather than the Champaign, IL writer David Foster Wallace who is often referred to as DFW. In which case, my DFW parody may have not made sense.

i use a little irish moss at the end of the boil. mostly just to use up what i have. most of my beers clear brilliantly with just sitting in the cold

i can't read the whole story but drinking plain water in vast quantities rapidly can kill you. leads to rapid hyponatremia (low sodium) brain swelling and death.
