Why you won't see Lisa Oldfield with a glass of bubbly in hand over the next few weeks.

It’s a very well known (and self-confessed) fact that Real Housewives of Sydney star Lisa Oldfield enjoys a drink.

But this month you won’t see her anywhere near a glass of bubbles – or anything stronger.

“You might know me from the show or you could have seen me passed out out in the gutter somewhere, it’s a very well known fact that I do like a drink,” she told Mamamia.

“But this year I am doing Dry July, giving up grog for an entire month to raise money to help people who are suffering with cancer.”

Listen: Lisa Oldfield spills all on the Real Housewives of Sydney drama. Post continues after audio.

But that doesn’t mean you have to become a hermit for the entirety of July. To spice things up, Lisa Oldfield has partnered up with Andrew Atwell, NYC’s mocktail master to create a delicious mocktail to enjoy for the month.

And in typical RHOS style, it’s named after her.

Behold the Lisa Lockstail.

LisaLockstail recipe. Watch the video playing above to see how it’s done.

– Four healthy dashes of Australian grapefruit bitters
– Three ounces (88ml) of freshly squeezed orange juice
– Two ounces (60ml) of grapefruit juice
– three quarters of an ounce (22ml) of freshly squeezed ginger juice
– A dash of agave syrup

Then shake it all up, pour over ice into your fanciest glass then top off with sparkling water. If you want to look really profesh, garnish with candied ginger or grapefruit peel and serve with a striped straw

Not only does it taste delicious, but it won't leave you feeling like you've been hit by a truck come morning.
