How to Make the Most Delicious Carbonated Cold Brew

Photos by Claire Lower

It would seem that we, as a nation, cannot leave our beverages alone, and are always looking for the next gimmicky sip. I read this article proclaiming cold brew and coconut La Croix the “drink of the summer,” and reacted with a mixture of incredulity and resignation.

Because honestly, coconut La Croix? That flavor of seltzer is La Croix’s worst—it tastes like diluted, carbonated sunscreen, and I don’t know why anyone would want to do that to cold brew. I’m also just not a huge fan of putting carbon dioxide in my coffee. (Cold brew on nitro is a totally different story, however; the bubbles are nice and small, and give the coffee a smooth, creamy mouthfeel.) Plus, I’ve tried some fancy coffee soda things, and found that they mostly just cause oral confusion. (See exhibit A below, which was the most perplexing thing I’ve ever put in my mouth.)

But I was told not to “knock it until I tried it,” so I tried it, to see it mixing delicious cold brew coffee with the worst La Croix flavor in existence would somehow result in something I would want to drink all summer long.

I mixed roughly equal parts of cold brew concentrate and satan’s seltzer, took a sip, and was … underwhelmed. It wasn’t exactly bad, but the combination of big bubbles and coconut essence muted the pleasant aspect the coffee’s flavor in a major way, and made it taste rather sharp, enhancing the bitterness.

Being fully aware of my prejudice towards the can of tropical bubbly water, I decided to try another flavor, and reached for a Polar or the black cherry persuasion. This ended up being much much worse, with the cherry essence and coffee joining forces to create a flavor…

Brewing Company Has the Tastiest Solution for Food Waste

There is so much surplus bread being created in the UK every year, that homeless shelters can’t even take in any more loafs destined for the trash.

My Story: Homebrewing Mixes Art, Science, and Community

When I relocated to Denver a few years ago, I knew one person in the whole city; my girlfriend (now wife) that moved there with me. We hadn’t made many new connections until we spent one Saturday afternoon at a local brewery taproom when we really met our first friends in Colorado.

We overheard a group of people discussing their upcoming brew day at the table next to us. Being an eager homebrewer myself, I asked them what they’ll be brewing. Before I knew it an hour had passed while we were chatting about homebrewing, and we were invited to join them to brew the next day. It’s been five years,…

Would You Drink Sewage Beer? New Brew Uses Treated Sewage Water.

Article Image

Bottoms up! A Southern Calfornia brewery is taking its beer from toilet to tap.

San Diego’s Stone Brewing has started making a beer using treated sewage water. The beer, called Full Circle Pale Ale, was recently unveiled for a tasting at their brewery. The beer was made using the recycled water from Pure Water San Diego, a program that has set out to provide one-third of San Diego’s water supply through its treatment system by 2035.

Stone Brewery is one of the largest (top 10) craft breweries in the United States and has made a concerted effort towards environmental sustainability. By brewing Ful Circle Pale Ale, which will be available for sale soon, the brewery is testing consumer demand for a process with clear environmental benefits. The result, however, may be less about taste buds (water doesn’t dramatically change the flavor of beer) and more about human psychology.

Would You Drink the Beer?

When you read that the Full Circle Pale Ale was made using treated sewage water, your first reaction was probably not, “That sounds delicious!” As earlier pieces in Big Think have discussed (“Our Sense of Disgust Is Holding Back Life-Saving Innovation“), the thought of drinking treated sewage water often triggers a sense of disgust–even though…
