A casual outdoor wedding - 100-ish guests, including maybe 10 to 15 children.
The food (dinner):
Burgers, salmon, some vegetarian main dish, salads and casual desserts (tarts, pies, cupcakes, fruit, etc.)
Late July. Early evening (5-ish) until late. Arrival Pimms cocktails followed by ceremony, bubbly toast, and then buffet dinner with wine. Party, dancing, music until late.
How much wine to buy? We have chosen a rose cava for the bubbly toast, one red, one white and a vinho verde. Totally confused about how much of each will be required. Any experienced folks out there who can advise? There will also be a canoe full of beer and soft drinks as well.
