The post-doc on the party. I ended up borrowing a friends
Rival drink fountain and made bulk sangria. The recipe is full of approximates, but it worked like a charm and everyone loved it. Sadly I don't have any photographs! The recipe makes about 3 gallons.
5L box Chablis
2 x 3L box White Zin
4 cups sugar
1 bottle Metaxa
4 large oranges
2 large apples (I used Fuji's)
6 limes
4 lemons
The day before:
1) Slice the fruit into whatever shapes you like.
2) Macerate the fruit with half the sugar and half the Metaxa in a bowl. You may need to add a bit of either kind of wine to get everything covered. Yes, the apples will float but they won't brown tho because of the citrus fruits.
3) Dissolve the rest of the sugar in as much Zin as it takes. I used a normal sized plastic pitcher barely half full. This was all done the night before and everything was in the 'fridge to get it nice and cool.
The day-of:
4) Drain the fruit, adding the liquid to the pitcher of sugar/Zin. Cover with a bit more Metaxa.
5) Loaded the fountain with 1/2 box of Chablis, 1 box of Zin, and 1/2 the pitcher of sugar/Zin and served the fruit on the side for everyone to help themselves as they liked. Also, had lots of ice handy.
6) Topped up the fountain as necessary with Chablis/remaining Zin/pitcher of sugar/Zin. Splashes of Metaxa were added too.
You can spike it with more or less Metaxa if you prefer, or skip the Metaxa and go for a cheaper brandy. Everyone seemed to like how boozy the fruit was. Of course, we could be a bunch of happy drunks. Even the non-wine drinkers were into it.
