minimum dose size?

Jan 31, 2024 |

I use the Hario switch to brew my coffee and am trying to reduce my caffeine consumption. Hence I would like to brew smaller cups of coffee. I am currently using 10g of coffee with 160g of water. (1:16 Ratio) I am wondering if there is a minimum amount of coffee...

Coffee Tasting Better in Ceramic Mug vs Thermal Tumbler?

Hey r/Coffee,

I'm coming here to ask about an experiment that was accidentally conducted yesterday during our morning brew to see if it makes any sense.

Every morning I brew coffee for my wife and I in a Clever Dripper. Typically I will brew to its max capacity and then dispense half into her thermos and half into mine. The two thermoses are identical Yeti thermal tumblers.

Yesterday morning however she wanted her coffee in a mug, so I dispensed half into a mug (Ceramic) for her, and half into the Yeti. Not long later I was called upstairs to be told how the coffee tasted even better this morning. I tried hers, and the fruity notes were in fact much more present than normal.

I assumed it was because hers just cooled faster, so I left the lid of my Yeti for awhile, and tried it again, but it was definitely not as flavorful. This morning I did the same experiment, with letting the coffee the tumbler cool down, and same result!

So that long explanation has led me here to ask, does this make any sense? Does dispensing the coffee straight into a thermal tumbler somehow change the flavor either from the stainless steel, or by somehow "cooking" it further?

EDIT: Getting multiple answers that stainless steel can change the flavor, and since I have asked this follow-up question twice, I'll ask here. Would dispensing into a glass/ceramic carafe and then pouring into the tumbler after it gets to temperature drastically reduce the flavor change since it spent the cooling time in glass/ceramic, or would I still get the same flavor change since I'm drinking it out of the stainless steel?
