Review: Silver Serpent Wort Chiller

This past Christmas I received the Silver Serpent stainless steel immersion wort chiller.  I've had the opportunity to use it a few times now, so it seemed appropriate to share a review with readers of Begin Brewing.

The chiller arrives in a cardboard box, ready to use.  Hoses and fittings are already attached.  A quick pressure check on brew day showed no leakage.  (The photo at left is from their Midwest Supplies web site, where mine was purchased.)

There are twist ties on the coils that I removed, not certain if they were food safe or temperature safe. There are no instructions in the box with the chiller to tell you whether to remove them or not.

I'm currently doing all my brewing in our home kitchen.  Our stove is fortunately powerful enough to bring a 5-gallon batch of beer to a rolling boil, so it's worked well.  The unfortunate problem is that the faucet on our kitchen sink is designed without an aerator, so there's no way to attach a garden hose fitting adapter to it.

My solution to the problem was to visit a local aquarium store and purchase a submersible aquarium pump for about $30.  Then, I tangle the "hose fitting end" into the drain, attach the other end of the tube to the outlet on the aquarium pump, fill the sink with cold water, and start the pump.  The pump pushes cold water from my sink into the chiller and out the other side.  This is the opposite direction from the design, but shouldn't have a negative effect on heat transfer as far as I know.

When I used the Silver Serpent in the winter on a 4 gallon boil I made in January, when our tap water was about 53 degrees Fahrenheit coming out of the tap, the wort chilled to yeast pitching temperature in around 25-30 minutes.

A few weeks ago, I brewed a batch of Belgian Tripel using the Brewer's Best extract based kit (which I'll talk about in a future post).  This 5-gallon high-gravity beer took almost 75 minutes to chill to yeast pitching temperature using the tap water (measured at 59.3 degrees Fahrenheit) and aquarium pump. That was longer than I expected, but still much faster than I was ever able to chill my wort before.


As you can see above, the temperature dropped about 10 degrees every 5 or 6 minutes.  With colder water on the incoming side, you'd probably see a faster decline in temperature.

Cleanup of the Silver Serpent is easy.  You remove it from the brew kettle, rinse it thoroughly, and brush off any residue from the brew kettle.  Once dried, it's ready to use again.

Being made of stainless steel, the Silver Serpent is a little more expensive than some of its copper competitors.  I've heard that you may see corrosion and other issues with the copper chillers, so I thought the stainless made a nice alternative.  It looks as good now as when I got it six months ago.

Things I've Learned Brewing with The Grainfather, Part 2

In the last post, I shared an overview of The Grainfather, recommended equipment to use with it, and an overview of the brewing process.  In this installment, I'm going to talk specifically about mashing and sparging. Having brewed over a dozen batches with it, I'm finally becoming very comfortable with the device, the mash process, and how to get what I want out of it. I don't consider myself a "master" of it yet, though. For those who have never done all-grain brewing, I want to provide a quick overview of the mash process itself. Mashing - With or Without The Grainfather The goal of mashing is to turn the starches in the grain into sugars. More specifically, you want to turn the starches into a mix of fermentable and unfermentable sugars that provide the flavor profile associated with the beer you are brewing. A sweeter beer might warrant more unfermentable sugars. A more dry beer will demand few unfermentable sugars. To a great extent, controlling the

Brewing with The Grainfather, Part 3 - Cleaning and Overall Thoughts

In Part 1 of this series, I introduced The Grainfather and discussed how to use it for mashing and sparging.  In Part 2, we talked about boiling and chilling the wort with The Grainfather and its included counterflow chiller.  In this final segment, we'll discuss cleanup and overall thoughts about the device and its usage. Cleanup Once you've pumped the wort from The Grainfather into your fermenter and pitched your yeast, you're well on your way to a delicious batch of homebrew.  Unfortunately, you've still got some cleanup work to do. The cleanup process in my experience will take 20-30 minutes.  It involves the following tasks: Removing and discarding the grain from The Grainfather's grain basket Cleaning the grain basket, kettle, recirculation tube, and wort chiller Cleaning all the other implements used in brewing (scale, scoops, mash paddle, etc.) At the end of the brewing process, there will be hops bags (if you used them), grain and other residu

Yellow Label Angel Yeast vs. Typical Brewing Yeast

I currently have my second batch of rice wine fermenting with the "magical" yellow-label Angel Yeast from China, and wanted to share some of the more unusual aspects of using it.  If you've never seen or used this yeast, I suspect you're not alone.  It ships in a 500 gram package that looks like this: What makes it "yellow label" is that yellow box you see in the upper left corner of the package.  This implies that it's yeast for distilling (though you do not need to have a still or distill the output to use it).  As I understand it, inside the package is a mix of yeast and other materials which will convert starch into sugar and directly ferment it, without the need for a traditional mash step.  This can radically shorten your brewing time.  For my most-recent batch of rice wine, I heated 3 gallons of water to 155F, poured it over 13+ pounds of uncooked rice straight out of the bag, let that soak for an hour, rehydrated some of this yeast in warm water,
