Mix items tell WithWine which bottles are in a mix. When the mix sells, WithWine takes those bottles out of stock and reports them as sold through the mix.
Before you start
Set List your mix for sale? to Yes on the mix, and set # of Bottles in Mix in Available Prices. A mix is 6 bottles unless you change it.
Each bottle you add must have List your wine for sale? set to Yes.
Choose the bottles
Go to Settings > Products > Mixes and click the mix's name (or click + Add Mix to create one).
Click Mix Items to open the section.
Tick Set mix items?.
Click Add Mix Items. A list of your bottles opens.
Click + next to each bottle until you have the right number of each. Use Filter products to find a bottle quickly.
Check the message at the bottom. Bottles count must match the number of bottles in the mix, for example 6 of 6. Accept only works when the numbers match.
Click Accept.
Click Save.
What happens next
Mix Items lists each bottle and how many, for example Barossa Valley Shiraz (2024) x 3.
To change the bottles later, click Update Mix Items.
Each bottle with stock tracking on goes down in stock when the mix sells, even if stock tracking is off for the mix itself.
Troubleshooting
A bottle's buttons show - 12 and + 12. That bottle isn't listed for sale. Open the bottle, set List your wine for sale? to Yes, click Save, then try again.
Accept is greyed out. The bottles count doesn't match the number of bottles in the mix. Add or remove bottles until it does.
