Do this in two equal batches, if needed.
Serve over crushed ice in stemmed glasses.
Notes / Tips / Wine Advice:
To crack ice cubes, put them in a heavy plastic bag, remove air from the bag, seal it, then put the bag on a cutting board. With a hammer or heavy rolling pin, gently break cubes into chips.
