Hario Replacement Coffee Bed Glass – Water Dripper Wood 2L (WDW-20)
Right in the middle of the tower hangs this one glass: the ground coffee rests inside it while cold water arrives from above, drop by drop. For hours it stays the quiet center of the whole process, until a clear, sweet coffee stands below.
Glass doesn't last forever – a knock while cleaning, a fine crack, and the drip rate falls out of rhythm. With this replacement glass you bring the Water Dripper Wood back to its original rhythm, without replacing the whole tower.
Why this particular glass matters
The shape and width of the coffee bed glass determine how evenly the water seeps through the grounds. When the glass sits exactly right, the drip rate stays stable – that roughly one drop per second which makes for a balanced, slow extraction.

Who it's for
For anyone with a Hario Water Dripper Wood 2L whose middle glass needs replacing – after a mishap while cleaning, or simply so a spare part is on hand.
What goes with it
Cold drip works best with an even, medium to slightly coarse grind. For anyone who wants a grinder that's affordable and precise: the Varia VS3 or the Comandante C40 hand grinder from our coffee grinder collection. The Varia VS6 or the Weber Workshops EG-1 is the premium option for anyone who wants more. For dosing, scales from the Normcore collection, or with app connectivity from the Acaia collection.

Roastery tip
