My husband and I thoroughly enjoy Kirkland Signature sparkling water. Erin McClure This Kirkland Signature sparkling water 35-count variety pack ($11) includes lime, lemon, and grapefruit flavors.

Costco's Kirkland Signature brand water is affordable and crisp, but there's a third-party brand who's actually bottling the water for Kirkland to sell.

The loser in our taste test was Kirkland's Italian sparkling mineral water. Granted, this was the only sparkling water we tried that wasn't flavored, which is why it's at the bottom of the list.
