Vine rows have a direction
Rows photograph best with the sun low and behind them. Ask which way the rows run and what time the light comes down them on your date, then set your ceremony time back from that.
Know what the vines look like in your month
Vines are green and full from late spring to autumn, turn gold as the weather cools, and are bare in winter. Bare vines with green grass between the rows still photograph well, but it is a different look. Ask to see photos from your month.
Keep the walk short
The best wineries for photos have the vines close to the reception room. A two-minute walk means you can step out for sunset and be back before the next course.
Think about the room after dark
Cellar doors and barrel rooms are warm and dark, which looks great with candles, festoon lights and warm bulbs. Bright white floodlights flatten everything, so ask what lighting is used at night.
Check what you can bring
Most wineries are licensed and pour their own wine, while a few venues are BYO. It changes your budget, so ask at the start of planning.
