Moving wort and beer between vessels is a routine but critical part of homebrewing. The right tubing and siphons help you transfer liquids without splashing, limit oxygen pickup, and keep your brew day running smoothly. The American Homebrewers Association (AHA) lists a siphon and tubing as essential equipment for any brewer, and highlights the auto-siphon as a simple way to pump liquid without introducing too much oxygen or other contaminants.

In this guide: We cover siphons, racking, chilling, keg lines, and cleaning so you can move beer safely and efficiently.

The Auto-Siphon: A Gentle Pump for Homebrewers

According to the AHA’s homebrew equipment overview, an auto-siphon is a type of siphon that creates a vacuum to pump liquid from one vessel to another. This design reduces the need to lift and pour heavy pots by hand, and it helps keep oxygen exposure low during transfers. The AHA notes that a basic siphon and tubing can also work, but an auto-siphon streamlines the process, and the AHA says a siphon and tubing streamline moving hot wort or finished beer.

Food-grade tubing is the standard for all homebrew transfers. The AHA’s introduction to kegging specifies that food-grade tubing is needed to connect CO₂ and faucet lines to quick disconnects. The same type of tubing is used with siphons, bottle fillers, and chillers. Always inspect tubing for cracks, stains, or lingering aromas before use, and replace it if it shows signs of wear.

Racking and Bottling Transfers

Our bottling equipment guide covers the bucket, filler and capper used at this stage.

The AHA’s all-extract homebrewing tutorial walks through the racking and bottling steps in detail. After fermentation, the beer is transferred (racked) from the fermenter to a bottling bucket using clean and sanitized equipment, such as an auto-siphon or racking cane. The tutorial advises creating a gentle whirlpool in the bottling bucket to evenly mix the priming sugar solution without splashing, and to avoid transferring the solid trub layer at the bottom of the fermenter.

Once the beer is in the bottling bucket, a bottle filler is attached to the spigot with a short piece of food-grade tubing. The AHA equipment page describes a bottle filler as a hard plastic tube with a spring-loaded tip. When the tip is pressed against the bottom of a bottle, beer flows; when lifted, the flow stops. This makes it easy to fill bottles consistently to about one inch from the top. After filling, caps are sealed with a bottle capper. The entire process relies on clean, sanitized tubing and a bottling bucket with a spigot, which the AHA lists as standard bottling equipment.

Cooling Wort with Immersion and Plate Chillers

The AHA’s equipment guide lists immersion and plate chillers as “nice to haves” that speed up the cooling of wort after the boil. An immersion chiller consists of a coiled length of copper tubing that is placed directly into the hot wort. Cold water is circulated through the coil, drawing heat out of the wort and bringing the temperature down quickly. A plate chiller works differently: it uses a stack of plates with one tube inside another. Hot wort is pumped through the inner tube while cold water flows through the outer tube, cooling the wort as it passes through.

Both types of chiller require food-grade tubing to connect to a water source and to direct the cooled wort into the fermenter. Regardless of the setup, all tubing and connections that touch the cooled wort must be sanitized, because any contamination after the boil can spoil the batch.

Keg Lines and Dispensing

See homebrew kegging basics for the full keg process, and the homebrewing equipment guide for the wider gear list.

The AHA’s kegging introduction explains that a home kegging system uses food-grade tubing to connect the CO₂ tank and regulator to the keg, and to run beer from the keg to the faucet. Quick disconnects attach the gas and liquid lines to the keg posts. The AHA recommends using different colors for gas and liquid disconnects to avoid mix-ups, especially with ball-lock fittings that can look nearly identical.

The kegerator owner’s manual provides detailed assembly instructions and safety warnings. It states that CO₂ cylinders contain high-pressure compressed gas and must always be connected to a regulator. Never connect a CO₂ cylinder directly to the product container. The manual also advises securing the cylinder with a strap, keeping it away from heat, and ventilating the area immediately if a CO₂ leak is suspected. The AHA kegging guide adds that before disassembling a keg, you must release all pressure. If the hatch does not budge, there is still pressure inside, and ignoring this can cause injury. Use the pressure relief valve or gently depress the gas-in poppet to let gas escape safely.

When it is time to serve, the length and diameter of the beer line affect the pour. The AHA kegging guide references “A Bottler’s Guide to Kegging” for details on balancing line length and pressure to achieve a proper pour without excessive foam.

Cleaning and Maintaining Tubing

Regular cleaning of all tubing and transfer equipment is essential to prevent off-flavors and contamination. The AHA kegging guide recommends completely disassembling the keg and soaking all components, including the dip tubes and fittings, in warm water with an appropriate cleaner. After soaking, rinse thoroughly with hot water. The kegerator manual describes flushing the beer hose by holding the open end under running water for 3 to 5 minutes while the faucet drains into a sink. This clears out any residual beer that could harbor bacteria or mold.

For sanitizing, the AHA kegging guide advises using a no-rinse sanitizer prepared according to the manufacturer’s instructions. Fill the assembled keg with the sanitizer solution, let it sit for 10 minutes, then flip it upside down for another 10 minutes to sanitize the top and hatch. Afterward, CO₂ can be used to push the sanitizer out of the keg through the liquid line, leaving a sanitized, oxygen-free environment ready for beer. The same no-rinse sanitizer can be run through siphons, tubing, and bottle fillers before each use.

Hot Side Safety and Scald Prevention

Moving hot wort and working with boiling liquids carries a real risk of scalds. The American Burn Association’s scald prevention fact sheet emphasizes that young children’s skin burns more quickly and deeply than adults’, and that hot water, drinks, and kitchen items can cause serious burns. While the fact sheet is aimed at household safety, the principles apply directly to the brew day. Set your water heater to no higher than 120°F (48°C), create a “no-kid zone” around the stove and brew kettle, and keep pot handles turned inward. If a scald occurs, cool the burn with cool (not cold) water, remove any clothing from the area, cover with a clean dry sheet, and seek medical attention.

The AHA’s all-extract tutorial adds a specific caution for glass fermenters: do not add wort that is over 100°F (37.8°C), because the thermal shock could shatter the glass. The AHA equipment page also reminds brewers to leave enough headspace in the brew pot to avoid a boilover, which can send hot, sticky wort over the sides and onto the burner or floor. Always lift and carry full pots carefully, and use a siphon rather than pouring whenever possible to reduce the chance of spills.

Frequently asked questions

What type of tubing should I use for homebrewing?

Food-grade tubing is the standard for all transfers, including siphons, bottling, and keg lines. The AHA’s kegging guide specifies food-grade tubing for connecting CO₂ and beer lines. Always check that the tubing is free of cracks, stains, or odors, and replace it if it shows signs of wear.

How do I clean my siphon and tubing after use?

The kegerator manual recommends flushing the beer hose with running water for 3 to 5 minutes to remove residual beer. For a deeper clean, the AHA kegging guide suggests disassembling components and soaking them in warm water with a homebrew-specific cleaner, then rinsing thoroughly. Before the next use, sanitize the tubing and siphon with a no-rinse sanitizer prepared according to the manufacturer’s instructions.

Can I use an auto-siphon with hot wort?

The AHA equipment page says a siphon and tubing help move hot wort, but check the manufacturer’s specifications for the maximum temperature the tubing and siphon can handle. When in doubt, cool the wort to a safe handling temperature before transferring.
