Growlers - Insulated
A growler is an insulated bottle for taking draft beer home from the tap, built to keep it cold and carbonated instead of flat and warm in an hour. DrinkTanks growlers use vacuum-insulated stainless steel and an airtight seal, holding carbonation for up to 30 days unopened on the Craft line and keeping drinks cold for 45+ hours (Craft) or 24+ hours (Session).
The only real decision is size and how you'll use it: 32 oz for a single pour, 64 oz to share, 128 oz for a group - plus whether you want the Craft line's pressure-rated seal for longer trips, or the lighter Session line for a quick grab-and-go fill.
Growlers buying guide
Open tabCraft vs Session: which growler line fits you?
Craft growlers are DrinkTanks' full-performance line: a 60 PSI pressure-rated seal that holds carbonation up to 30 days unopened and keeps drinks cold 45+ hours, built for camping trips and longer stretches between refills. Session growlers use a simpler leakproof cap, skip the pressure rating, and keep drinks cold 24+ hours - lighter and easier for a same-day grab-and-go fill.
What size growler do you need?
Size comes down to how many people are drinking and how long the trip is. A 32 oz growler suits one person or a short outing. A 64 oz growler, DrinkTanks' best-selling size, covers 2 to 3 people or a full day out. A 128 oz growler is built for groups, tailgates, or trips where refilling isn't an option.
Both lines come in more than one size: the Session 64 oz Growler and Session 32 oz Growler mirror the Craft sizes at a lighter weight, and the Session Adventure Kit bundles a 64 oz Session growler with two pint cups if you want everything in one box.
Travel Keg Pro takes it further - it pairs the 64 oz Craft Growler with the Kegulator Cap, so the same insulated body that holds a fill cold for 45+ hours also dispenses on tap instead of pouring straight from the neck.Not sure how many beers a given size actually holds? How Many Beers Are in a Growler breaks down the exact math for every Craft size, in cans and in pints, so you can match the size to how many people you're actually pouring for.
