Tanqueray makes one of the finest gins, specifically London dry gin. Gin in general is pretty much vodka, composed of a neutral spirit. However, select botanicals, spices and flavors are added. They’re rarely sweet, hence the dry, but it’s still a festivity of flavors. Tanqueray unsurprisingly makes their own gin and tonic blend in a can. It’s not for everyone, though personally I enjoy it. The cocktail is dry, and bitter, thanks to the quinine in the tonic. The sweetness that is present is like a mirage; it’s not there for long.
It’s worth noting that Tanqueray’s London dry gin tastes very similarly to Kirkland’s own London dry gin, so if you have a Costco membership, enjoy getting good gin on the cheap, and buying your own tonic water (such as a diet Canada Dry tonic water). Gin also pairs great with ginger ale, with the resulting cocktail not being so bitter and quite refreshing.
