Best wort chiller

Most homebrewers outgrow ice baths for cooling wort down to pitching temperature within a short time of getting into all-grain brewing. Ice baths are also difficult to use for anything more than 2.5-gallon brews and can easily take the joy out of an otherwise smooth brew day.

Cooling your wort quickly reduces the chances of introducing bacteria into the beer before pitching the yeast. Eventually, you will want or need an easier and quicker way to cool your wort which is where a wort chiller comes in.

What is a Wort Chiller?

A wort chiller is exactly what it sounds like. This is a piece of equipment that cools your wort down to pitching temperature within a short time, preferably to between 60°F and 70°F for ales and between 40°F and 50°F for lagers. The ideal cooling time from boiling to room temperature is 30 minutes or less.

So why not just let the wort cool in its own time?

First, it is important to reach the yeast pitching temperature. Adding the yeast to your wort while the temperature is too high kills the yeast and renders it useless for fermentation.

Secondly, a ‘cold break’ is necessary for the final quality of the beer. Rapidly cooling the wort allows the proteins in the wort to fall out. The result is clearer and aesthetically pleasing beer.

Finally, bringing down the wort temperature quickly drastically reduces the risk of infection. Wild bacteria and yeast grow exponentially in warm, sugary wort. Cooling the wort quickly narrows this window for infection.

Types of Wort Chillers

There are three main types of wort chillers: immersion chillers, counterflow chillers, and plate chillers.

Immersion Wort Chillers

Copper Immersion Wort Chiller

An immersion chiller connects to a sink or garden hose. The chiller is immersed in the hot wort. As cool water circulates through the coils, it draws heat from the wort, thereby cooling it. A good immersion chiller can cool your wort from boiling temperature to room temperature in about 20 minutes.

Immersion wort chillers can be made from either copper or stainless steel.

Counterflow Wort Chillers

Counterflow wort chillers generally have two tubes, one inside of the other. The inner tube carries the wort while the outer tube carries the cool water.

Stainless Steel Counterflow Wort Chiller

As the wort circulates inside the inner tube in one direction, the cool water circulates in the outer tube in the opposite direction. The wort cools as it flows from the boiling kettle into the fermentation vessel.

A counterflow chiller may be used with a pump to circulate the liquids and may be built from stainless steel or copper.

Plate Wort Chillers

Plate wort chillers work very similar to counterflow chillers. The hot wort flows through the plates in one direction while the cooling water flows in the opposite direction on the other side of the plate. The cool water absorbs the heat from the wort and cools it.

Plate Wort Chiller

A plate wort chiller may also be used with a pump to circulate the liquids.

Final Thoughts on Rapid Cooling Wort Chillers

You can have a great wort chiller regardless of your budget and brewing setup. With immersion chillers, go for larger diameter coils and a longer length for optimum cooling efficiency. Keep in mind that these chillers use up quite a bit of water so keep some buckets handy to collect the runoff to reuse for watering plants or cleaning up.

Plate chillers are compact and the perfect choice if you have space constraints. These are also quite efficient, especially for smaller batches. Consider installing a filtration system in your kettle to avoid clogging your plate wort chiller.

Finally, counterflow chillers are very efficient especially if they are long and have large tubing diameter. Remember to circulate back-flush cleaner and sanitizing solution through the coils immediately after use to keep leftover trub and particles from infecting your beer.
