Where can I get orange flavoured vodka in Glasgow?! Help!?

Peckhams in Merchant City, bit pricey but they've got everything, its just off Ingram street near the polo lounge.

If you don't need it right away, make your own! Just zest 6-8 oranges and put it in decent plain vodka. You only want the orange part of the peel, not the bitter white stuff underneath (a fine cheese grater works good). Let it sit for 2+ weeks and then strain out the peel pieces and add sugar to taste. You will have an awesome orange flavored vodka. This is similar to how they make lemoncello in Italy.
