The Joys of Racking Wine….

Racking your wine is a necessary evil. We know it can be tedious, but it the end it is so worth it.

Things to keep in mind when racking:

Cleanliness: We cannot express this enough. The cleaner your cellar, the less risk you have of spoilage, the better your wine will be. Aka SANITIZE EVERYTHING!! (however if doing MLF rinse with hot water as not to kill the ML bacteria) Use a solution of potassium metabisulfite dissolved in warm water. Add 2 tbsp to a 5 gallon bucket of water. Make sure that everything that will touch your wine (siphon, hosing, carboys, stirring rods) are all rinsed with this solution. Do not rinse it off with water, just shake off any excess droplets.

Primary Racking: Rack after your primary alcoholic fermentation is complete. This protects your wine from any initial microbial fermentation issues. Getting the new wine off of the dead yeast cells in important for the health of your wine to prevent off aromas.

Secondary Racking: Rack after the Malo-Lactic fermentation has finished. At the second racking you will want to rack your wine into an aging vessel. Whether that is a stainless steel tank or an oak barrel. Don’t forget to sulfite, unless you are doing MLF.

Third and/or Fourth Racking is used more for clarification purposes. Solids and fining agents (if used) will fall out of suspension and form a layer on the bottom of your aging vessel. Racking every 2-3 months, will consistently clarify your wine.

Using a pump makes life so much easier. You can pretty much sit back and relax with a glass of wine while your juice is being transferred. If you don’t have a pump the best way to rack is by using a siphon and the gravity method. Put the primary vessel up some place high (a table) and rack into your new vessel on a lower surface (floor).
