UPDATE: Universal has released this picture from the park showing 1,000 lucky guests holding their free Butterbeer today.
Universal Orlando - home to The Wizarding World of Harry Potter - has announced that one million Butterbeers have been sold in the park.
To celebrate the occasion, today only park guests are receiving a voucher good for one of these delicious drinks.
If you're looking to celebrate the occasion at home we recommend checking out our Butterbeer recipe.
It was back in August when Universal revealed there had been 1 million riders on Harry Potter and the Forbidden Journey, suggesting the unique rides are significantly more popular than the unique food and drinks (unsurprisingly).
