A new way to keep a beer bottle cold
Once a bottle of beer is opened, there are few options to keep it cold while you’re drinking it. You can either consume it before it gets too warm, or you use a beer koozie. In the case of bottles, that’s usually a neoprene koozie that with a zipper to make it snug.
A new option just came on the market by the name of Brewtis the BottleKeeper. It’s a stainless steel bottle container with an interior neoprene liner that its makers say will keep a bottle colder than the zip-up koozie. The bottom screws off so you can put in the bottle – at this point, only one of the taller 12-oz. containers. According to the website, it will keep the beer “up to 40% colder than a standard beer ‘koozie.”
The makers sent us a Brewtis to review, so naturally we went into the Road Trips for Beer laboratory to conduct a scientifically questionable experiment.
The conditions: Three bottles of Samuel Adams Winter Lager were opened at the same time. We placed one into the Brewtis, the second into a zip-up neoprene koozie, and left the third bare. Using an instant read digital thermometer, we measured the temperature of the beer every 10 minutes for an hour. (Because if it takes you more than an hour to drink a beer, why are you even reading this?).
The starting temperature of all three bottles was 41 degrees Fahrenheit, and the room temperature remained a consistent 75 degrees throughout the experiment.
Using “SS” for the stainless steel Brewtis, “NE” for the neoprene koozie, and “BB” for the bare bottle. Here’s what happened.
- After 10 minutes: SS, 44 degrees; NE, 43.4 degrees; BB, 49.7 degrees.
- After 20 minutes: SS, 46.6 degrees; NE, 46.5 degrees; BB, 54.7 degrees.
- After 30 minutes: SS, 49.4 degrees; NE, 48.5 degrees; BB 58.3 degrees.
- After 40 minutes: SS, 51.2 degrees; NE, 51.1 degrees; BB, 61 degrees.
- After 50 minutes: SS, 53.3 degrees; NE, 53.3 degrees; BB, 62.8 degrees.
- After 60 minutes: SS, 54.6 degrees; NE, 55.1 degrees; BB, 64.2 degrees.
As you can see, the Brewtis and the koozie stayed pretty consistently within a degree or so of each other until the 50-minute mark, when the temperature of both hit 53.3 degrees. At the conclusion of the experiment, the Brewtis was 0.5 degrees colder.
Does this discredit the claim of “up to 40% colder … .” Well, technically it’s within that range, though barely. And, as mentioned above, our experiment was scientifically questionable.
And there’s another factor: The Brewtis includes a screw on cap, which if utilized between sips, should make a significant difference in the temperature as time passes. The makers told us that the cap was indeed left on during their testing, which would have kept it much colder for a longer period.
But the most exciting part for the beer traveler is that you can put an unopened bottle in the Brewtis and it will protect it from breakage far better than a regular koozie. If you’re bringing a bottle of something special to a party, you can use the Brewtis to transport it and it likely will be cold enough to pour when you arrive. Or you can use it to protect the bottle while you’re on a road trip so it will make it back home in one piece. Plus, most airlines allow you to pack beer in your checked luggage as long as it is properly packed, which usually involves bubble wrap and zipper-seal plastic bags. With the Brewtis, you can just put in an unopened bottle, tighten down the cap, and you’re good to go.
The makers of Brewtis told us that they plan to offer different sizes and colors in the future, including for 22 oz. and 750 ml bottles, popular sizes for many craft beers.
