Gordon's Sloe Gin & Tonic

1. Take a tall glass filled with ice cubes. The tall glass ensures that there is enough space for the gin, tonic, and ice, while the ice cools and dilutes the drink for a refreshing taste.

2. Next, use a peg measure to pour precisely 50ml of Gordon's Sloe Gin into the prepared tall glass. 

3. Once the gin is added, top up the glass with 125ml of tonic water.

4. To add a final touch of garnish, cut a lime wedge using a sharp knife and a chopping board. Squeeze the lime into the glass and drop it in.
