Under the hood

Two zones, honest ranges.

Temperature ranges align with sommelier serving and storage guidance. Capacity tiers come from common dual-zone form factors at Fridge.com.

  1. 01

    Total bottle count

    Reds + whites + sparkling. The total drives form factor (compact, mid, large, XL).

  2. 02

    Zone allocation

    Whichever wine type is larger gets the bigger compartment. Reds run warmer (55–65°F); whites and sparkling run colder (40–55°F).

  3. 03

    Form-factor recommendation

    ≤12 → small. 13–24 → mid. 25–48 → large built-in. 48+ → tower or full cellar.
