Orange '81

This mocktail is surprisingly delicious--fresh and light, but so very appropriate for the holidays.  The oat milk gives it a little body and creaminess.

1 1/2 oz. orange juice
1 oz. oat milk
1/4 oz. Royal Rose Rose Syrup
1/4 oz. maple syrup
freshly grated cinnamon
freshly grated allspice

Combine first four ingredients over ice and shake vigorously. Pour into a rocks glass and top with a splash of soda.  Grate spices on top and serve.
