They offer ready-to-drink cold options that are all flavored and sweetened. The Cinnamon Bun Latte flavor’s packaging was cute, but it was too sweet and barely tasted like coffee.

Califia

This brand has a wide range of products, including iced coffees and cold brews in many flavors. The caffeine level is on par with other brands, but it tastes strong.

Califia products seem thoughtfully designed, with the neck of the bottle easy to hold while pouring. They’re also affordable at about $5.49 per 48-fluid-ounce bottle.

Chameleon Coffee

These concentrates are steeped for 11+ hours and come in six flavors. The Black unsweetened variety is smooth yet bold, without being overly strong.

This coffee is more expensive, but it’s organic and comes in a recycled glass bottle. Their classic black concentrate is one of the better-tasting coffees.

Rise Brewing Co.

This brand only offers nitro cold brew in cans. There are six varieties and the vanilla flavor tasted better than the original black which was too strong.

While Rise isn't the top choice of coffee, it's an excellent contender for a canned caffeinated beverage when you need it quickly, and specifically, without ice.
