The immersion chiller and ice bath have something in common – they cool the entire batch of wort at once.
That’s why it was strange switching to a plate chiller where you only cool a portion of the wort at a time.
But then I read the Brutus 10 plans. Surprisingly, Lonnie Mac does not pump through the Therminator in a single pass, but rather recirculates the wort back into the boil kettle until it reaches pitching temps. He doesn’t say in the plans why he does it this way, but I found this HomebrewTalk thread where he explains it:
“It works like a charm and there are MANY reasons for doing it this way…I reach the DMS Gspot in under 3 minutes and lager temps in under 20… That is all that matters. Trub is in the pot and sweet cold wort in the fermenter.”
There is also Jamil’s famous Whirlpool/Immersion chiller which follows the same principles as Lonnie’s plate chiller method.
So that got me thinking about recirculation instead of a single pass. I ended up trying both techniques. I’ll tell you later which one I prefer, but first let’s look at the advantages and disadvantages of each:
Single Pass Chilling
This is the most common way to operate a plate chiller. After the boil (or whirlpool), you drain from the kettle, through the plate chiller, and into the fermenter.
Advantages: You can cool the wort more quickly this way. How long does it take to cool? As long as it takes to empty your kettle. You can even use gravity to feed through the chiller.
Disadvantages: Accurate temperature control is more difficult. If your ground water is too warm, you will have to pre-chill it, pump ice-water, or cool the fermenter to pitching temperatures after the fact. Also, the cold break gets carried over to the fermenter.
This is an alternative way to operate the plate chiller. Instead of running the wort directly into the fermenter, you recirculate back into the boil kettle until you reach you desired temperature. Then you redirect the flow into the fermenter.
Advantages: Easier temperature control. You cool the entire batch at once, locking in late addition hop flavor and aroma. Possible reduction in DMS* (see below).
Disadvantages: Takes longer than single pass cooling. It requires a pump to return the wort to the boil kettle.
*This is a debated topic so I’m not ready to say it’s a sure thing. Here is what Jamil says about DMS and why his whirlpool chiller solves the problem
“DMS is often described as a cooked corn aroma that often plagues lager brewers. The thing is, the lighter pilsner malts contain more SMM (S-Methylmethionine), which gets hydrolyzed to DMS during the boil. Yes, this gets driven off, but unless you’re doing 100 minute or longer boils, there is still some SMM left behind. The neat thing is, if you can get the temperature of the wort below 140F (60C), then SMM will not be converted to DMS. The whirlpool immersion chiller will drop the temp of the wort below 140F (60C) very quickly, resulting in far less DMS in the finished beer. On the other hand, counter flow and plate chillers continue to hydrolyze SMM into DMS while sitting there at near boiling. “
What do I do?
In 5 batches on my Brutus 10 I’ve done single pass twice and recirculation three times. I prefer recirculation so I’m going to stick with that until I find a reason to abandon it. Let me explain why I like it.
The big advantage of single pass chilling is the time savings, but with recirculation I am able to cool the wort from boiling to 65°F in 15 minutes. Given the other advantages, that is plenty fast enough to go with this method.
The single pass method took 10 minutes. I couldn’t run the pump wide open because the wort wouldn’t cool enough. It would have been quicker if I pre-chilled the cooling water.
My method with recirculating is to knock the wort down to about 140°F with a garden hose. Then I disconnect the garden hose and connect my HLT which is filled with ice water. I use the second pump to recirculate the ice water through the chiller and I hit the 60’s in no time. This isn’t a new idea – it’s the one from Lonnie’s original Brutus 10 plans.
With the single-pass method, the temperature control was a real downside. It’s been a HOT summer in Denver and my ground water is around 70°F. I like to pitch the yeast right away, so bringing the wort down to pitching temps after the fact isn’t going to be a long term solution. Sure I could pre-chill the water or use ice water, but the process is still too variable. Even with an inline thermometer it was difficult to get the exact right temperature out of the plate chiller.
I like to know exactly what the wort temp is when I drain into the fermenter and recirculation gives me that level of control. Plus I can leave the cold break (at least most of it) behind in the kettle. The 15 minute chill time is also in 90°F+ heat, so in the winter it will be even quicker.
So why not use an Immersion Chiller?
Well for one I already bought the Therminator ; )
Honestly though, I do love this thing. I mean look how compact it is. With limited space, that’s a HUGE deal for me. My old 50′ immersion chiller took up 5 times the space.
But don’t think that a plate chiller is “a step up” from immersion chillers. In fact, there is a shift back to using them due in a large part to Jamil’s whirlpool chiller. Some people are even switching from a plate chiller to an immersion chiller.
Plate Chillers: Guide, Tips and Best Plate Chillers
Who doesn’t love a beer? Think about it. You come down home from a tough day at work. What better way than soothing and relaxing into the confines of your home than beer? The love for beer is somewhat outstanding, and it’s fair to say not many people cite their life without diving into a bottle of chilled beer.
But there’s a thing with the beer bottles. You do tend to get sort of wilted with the prepackaged beer. It’s a reason why people these days are looking at home brewing rather than just buying the beer cans off the gas station.
Before nodding to home brewing, though, take a look at what you’re looking for. Sure, brew kettles are important. However, there is a load of components and accessories that make up the process of home brewing. Plate chillers or wort chillers, as they are known, are a major integral component of a homebrew starter kit.
Here, we look into the best plate chillers around and review them. We present an in-depth review of plate chillers along with the buying guide and tips for you. But first, let’s have a few words on plate chillers.
What is a Plate Chiller?
You use a plate chiller to quickly cool the boiling wort as part of the home brewing process. During home brewing, cooling the wort is one of the most important tasks. Efficient cooling will allow you to pitch your yeast for successful fermentation. Previously, when plate chillers were a thing of sketches on design board, ice baths or dilution was the only way to cool your wort.
Today, plate chillers cool your wort in a fraction of time. It works similarly to a car radiator and has copper lines via which the water flows in the opposite direction. The heat exchange takes place, and that allows the wort to achieve peak cooling effects. Plate chillers are a worthy investment and something you’d attune to once you get your hands on it.
Components of Plate Chillers
Usually, plate chillers come out of the packaged box as a ready to be fitted state, but that’s not always the case. Add to it, the flexible options like the in and out pipe and hose that you need to add for on your own, there is certainly scope for getting to know about these little components. A bit of knowledge will help you to control and cool your wort much efficiently, ultimately paving the way for a nicely brewed beer.
A normal typical instance of plate chiller is made of these following:
Copper Plates: Plate chillers are designed with copper plates placed on top of each other with space in between them for the flow of the water and wort in different tubes so that the wort can be cooled off quickly.
Tube: The tube has an inside and outside tubing. It happens to run the wort, and the water in the opposite direction cools the wort throughout the process.
Hose: Hose is the inlet for the inside and outside channel of entry and exit for water and wort. It controls the flow of the tubes.
Plate Chiller Requirements:
There are quite a few times when we are just simply stuck to the ground and don’t know how to proceed further. For many of us, who are into the first-time buyer of plate chillers, the world may seem intriguing. Here’s why we are around. We help you along in your quest for a good plate chiller with a few guidelines. Check them out.
You get different plate chillers available at different price spectrums. All of these differentiate themselves from functionalities and performance. However, cooling downtime is something you need to look at first. Look for the plate chiller with the lowest cooling downtime.
Quantity of the wort
Not all plate chillers cool gallons of wort. Mainly plate coolers are associated with a low volume of wort when it comes to cooling. Look for the quantity of wort that the plate chiller supports when it comes to cooling. The higher, the better.
Build quality and durability
A major thing to look for whenever you’re buying a plate chiller or any other machine is the aspect of build quality and durability. Most of these come with a pretty good warranty period but cast a keen eye on them to see which stands still when it comes to the race of build quality. A good investment in a one-time durable plate chiller will save you from reinvesting on it time and again.
The average life of the chiller
You can’t ignore this one, can ya? Every plate chiller has an average life cycle that it will run for. Look for the one that will give you more years down the line rather than something that just dwindles down a few years on.
Another major factor when it comes while buying a plate chiller is pricing levels. We all know, there are plate chillers available at a different spectrum of pricing. And finding the best value for money is what we are seeking for. Look for the competitive pricing levels and find something that fits your purpose and needs rather than just some fancy ones.
