要製作清涼的葡萄氣泡水，首先需要用鹽水將葡萄浸泡約10分鐘，這樣可以有效去除表面的雜質和農藥殘留。浸泡後，將葡萄仔細洗乾淨。接下來，用工具（如杵棒）不斷敲打或是直接用手搾出葡萄的果汁，盡量讓果肉中的汁液完全釋放出來。完成後，使用濾網過濾掉果皮和其他雜質，確保得到純淨的葡萄汁。

接著，將過濾好的葡萄汁倒入一個大杯中，然後加入大量冰塊，這不僅能增加飲品的冰涼感，還能稀釋果汁的濃度，讓口感更加清爽。隨後，加入氣泡水，這會為飲品增添一層輕盈的氣泡感。如果偏愛更甜的味道，可以將氣泡水替換成雪碧，這樣飲品會有一點甜甜的果香味。

最後，加入兩到三片新鮮檸檬，檸檬的酸味能夠提升整體的風味，使飲品不會過於甜膩。將所有材料充分攪拌，使各種味道融合在一起。這樣，一杯清涼爽口的葡萄氣泡水就完成了。這款飲品不僅製作簡單，而且非常適合夏日享用，能夠快速帶來清涼和滿足感。

To make a refreshing grape soda, start by soaking the grapes in salt water for about 10 minutes. This helps effectively remove any surface impurities and pesticide residues. After soaking, rinse the grapes thoroughly to ensure they are clean. Next, use a tool like a pestle to gently crush or manually squeeze the grapes to extract the juice, making sure to release as much of the juice from the pulp as possible. Once you've collected the juice, strain it through a sieve to remove the skins and any other impurities, ensuring you have pure grape juice.

Pour the strained grape juice into a large glass, then add plenty of ice cubes. The ice not only cools the drink but also dilutes the juice slightly, making the flavor more refreshing. After that, add sparkling water, which will give the drink a light and bubbly texture. If you prefer a sweeter taste, you can substitute the sparkling water with Sprite, adding a hint of sweet, citrusy flavor to the drink.

Finally, add two to three slices of fresh lemon. The tartness of the lemon will enhance the overall flavor, preventing the drink from being overly sweet. Stir all the ingredients thoroughly to blend the flavors together. And there you have it—a refreshing and crisp grape soda. This drink is not only easy to make but also perfect for enjoying on a hot summer day, offering a quick burst of coolness and satisfaction.
