So years ago I discovered double wall glass mugs.
Nearly perfect but just too fragile, leading to lots of orders:
They are nearly ideal. Zero flavor retention, easy to clean, great for hot coffee and ice cold beer and tea and sparkling water. I get the 18oz version in two packs. Plus they insulate well so no condensation and I can savor.
But they break so damned easily. Which is why I’ve repurchased so many times.
A while ago the Wirecutter recommended a glass lined bottle from Purist and I bought one. It’s as promised but the shape is too deep to hand wash and the lid is impossible to clean internally. so off I went.
And yes I firmly believe that coffee flavor is best from a wide opening shape and glass or ceramic. Reddit agrees… mostly.
The main features I want are insulation, glass or ceramic lining and large at 16oz or so. Two full cups from my French press. I found this Asobu:
It’s… excellent. Super slick coating, insulated well, a breeze to clean, coffee tastes great. Nice and wide so the aromas are good.
The shape is a lot like my Yeti that I still have.
And Yeti does have ceramic lined mugs now, but only 4 and 6 ounce:
The Asobu is very well made:
I’ve had it a few days, rigorously testing with coffee, tea, sparkling water, beer, mint tea and it’s great. Super slick ceramic, nice cork, wide and stable, good value at $30. Worthy of my YouShouldBuy category!
