Now I Wish I Had The Bigger Growler

I like the way the keg cap works. Took a little time to get the hang of the CO2 injector but I figured it out. My 64 oz. growler went dry too fast! That may have been my fault.
Yummy! Yummy!

Bought the 64oz for myself and one for a friend for his birthday and the keg cap system for both....all I can say is “Dilly Dilly”!!! This is the most awesome growler ever. Went to a local brewery to snag some Midnight Expresso Porter.....stayed fresh (although it only took a few days to consume) and we will be using it back in WI for some Great Dane Stone of Scone Scottish Ale....yum! And it’s not just for guys! The guy we gave it to loves it even more than me. If you want a “wow” for a drought beer drinker, this is it.

Keg Cap System

Add the optional Keg Cap, and the DrinkTanks Growler turns into a personal keg that will keeps beer fresh for up to 5 days after it’s opened.


Not since 1887 has craft beer been as popular as it is today. With more and more breweries springing up across the country, Founder Nicholas Hill and his dad saw the need for a container made with the same level of quality and care. They got to work, and after his father passed away in 2013, Nicholas continued their work and brought DrinkTanks to life with crowdfunding.

Manufactured from high-grade stainless steel, the Growler features double-walled vacuum insulation and a revolutionary leakproof dual-bail cap system that preserves the carbonation far longer than any screw cap. Cold beverages stay cold for up to 24 hours without any sweating or condensation and they stay fresh for up to a week in the fridge.

And because the beverage only touches steel, there’s no loss or alteration of the premium craft brew taste.

Dishwasher safe and BPA-free, the DrinkTanks Growler is a great-looking way to present and store premium brews. more Their Story
