Racking wine means transferring it from one container to another, usually with a siphon, while leaving sediment behind. You will see the term in many wine-kit instructions. Understanding the purpose makes this step easier to plan.
This Craft Master Karl guide draws on the racking sections of ABC Cork's Wine from Kits booklet. Follow your own kit for when to rack, which vessel to use and how much of the sediment to leave behind. The right timing depends on the batch and the stage.
What the racking equipment does
A basic setup uses a rigid racking tube connected to food-grade siphon hose. A sediment tip helps keep the inlet above the material settled at the bottom. An autosiphon uses a pump action to start the flow; choose tubing and fittings that match your actual equipment.
A tube holder can help you keep the inlet where you want it. The goal is control: draw wine from above the sediment, then adjust the inlet as the liquid level falls.
Check the equipment before the transfer. A poorly fitting hose, damaged tube or unstable vessel can turn a straightforward job into a frustrating one.
Prepare both vessels before starting
Have the destination vessel ready, with enough capacity for the transfer. Clean and sanitize the vessels, hose, tube and other wine-contact surfaces according to the products' labels. Our cleaning and sanitizing guide explains the two jobs.
A gravity siphon needs the source above the receiving vessel. Use stable surfaces that can safely support the containers and their contents. Arrange the setup before handling the wine, and follow the vessel manufacturer's handling directions.
Make sure the hose reaches the receiving vessel without being stretched or kinked. Keep the destination end under control before starting the siphon.
Transfer slowly enough to protect your work
- Place the inlet above the settled sediment.
- Start the siphon using your equipment's intended method. An autosiphon can start the flow without mouth contact.
- Watch the inlet and liquid level throughout the transfer.
- Adjust the tube carefully as the level drops, avoiding disturbance of the sediment.
- Stop when continuing would carry unwanted sediment into the receiving vessel.
Follow your kit's directions for the receiving vessel, headspace, airlock and the next step. Avoid unnecessary splashing and exposure, particularly as the wine moves beyond active fermentation.
Plan for a little wine to stay behind
Trying to recover every last drop can pull sediment into the next vessel. A controlled transfer may leave a small amount of wine with the sediment. That is one reason bottle yield is approximate.
For example, our beginner kit-size guide explains why a nominal 23 L batch is described as approximately 30 standard bottles. Transfers and sediment affect what you actually bottle.
Do not compensate for a loss by adding water, extra ingredients or another transfer unless your kit instructions call for it. Ask for kit-specific guidance if the remaining volume or headspace seems wrong.
Finish by cleaning and making a note
Clean the emptied vessel and equipment promptly, before residue dries in place. Record the transfer date, specific gravity and any observations in your wine log.
If you are unsure whether your batch has reached the transfer point, check the readings required by the kit. Read how to check fermentation with a hydrometer, or contact Crafted Series with your kit details.
