County Line Kitchen 64 oz Cold Brew Coffee Maker: problems, parts and running costs

Checked: 2026-10-10

Summary

Sediment is the most reported problem: the 160-micron steel mesh lets fine grounds through, so expect a gritty or muddy bottom unless you settle, decant or refilter. Running cost is low because the brewer is non-electric with a reusable filter, leaving coffee grounds as the main yearly expense. At or below $30 delivered new it is good value, and above $40 you should compare the Takeya 2-quart glass brewer at $42.99 direct.

Common problems and fixes

Sediment and a muddy bottom — the leading complaint. WIRED’s testers found the filter too porous and the coffee gritty, and an owner who had both sizes warned the filter leaves sediment. A coarser grind, settling and decanting, or passing the brew through paper helps. No defect rate can be calculated from the anecdotes. [1][2][16][17]
Leaks when shaken — WIRED reports liquid escaped from the closed jar during a shake test even with the lid sealed, while Shouldit’s 1-quart sample stayed watertight, so results vary by lid, fit and gasket placement. Check the gasket and threads, keep the jar upright and do not rely on a spillproof seal. [1][2]
Glass breakage and thermal shock — the soda-lime jar can chip or crack if struck, dropped or hit with hot liquid, and the seller-hosted manual warns about thermal shock; a filled 64-oz jar is heavy, so do not carry it by the lid alone. This is inherent glass risk, not a verified production defect. [3]
A tapered infuser limits how strong a concentrate you can make — owners report the conical filter restricts coffee mass and saturation, so some steep grounds loose in the jar and insert the filter only at the end; this is a workaround, not the standard method. [18]
Mesh and seal contamination if neglected — coffee oil and trapped wet grounds build up in the filter pores and gasket crevices; the maker says to wash after every batch to prevent mold, and Shouldit removes the gasket and flip cap for a deeper clean. [5][2]
Brewing takes most of a day or longer — the maker’s guidance is 12–14 hours at room temperature or 24–48 hours refrigerated, and Shouldit preferred longer than 18 hours, so a fresh cup cannot be made immediately. [4][2]

Parts and consumables

Reusable 2-qt stainless infuser/filter — a new eBay listing at $15.40 item plus $10.60 shipping ($26.00 before tax), while RetailMarket advertised a purported 2-qt County Line filter at $43.49. Replace only if the mesh tears or the frame bends; the maker part number was not confirmed. [10][11]
Wide-mouth silicone filter rim gasket — the maker specifies 2.7-in inner and 3.10-in outer diameter for the 1- and 2-qt filters; a branded 3-pack was listed at CAD $7.49 on Walmart Canada, which is not a US dollar price, and no US SKU or price was found. [6][12]
64-oz replacement wide-mouth glass Mason jar — not model-exclusive if the lip and threads match; Ball 64-oz wide-mouth jars were listed at $14.79 for a six-pack at Target, about $2.47 per jar if all six are used. [6][13]

Yearly running cost

Electricity is $0 a year directly and mandatory disposable filters are $0 a year, because the brewer has no motor, heater or wall plug and the washable metal basket replaces paper filters. The recurring expense is coffee: an illustrative scenario of one 2-quart batch weekly at 100 g of grounds per batch and an assumed $12 per 1-lb bag costs about $137.57 a year, rising to $206.35 at 150 g per batch. Replacement parts are condition-based, so no average annual parts expense is documented.

When it is a good buy

At or below $30 delivered new it is excellent value for a buyer who needs glass and a reusable strainer; between $30 and $40 delivered it is fair if the lid and 64-oz jar fit the fridge. Above $40, compare the Takeya 2-quart glass brewer at $42.99 direct, or the OXO Compact 24-oz brewer at $39.99 direct if a smaller, cleanly drained concentrate is preferable. October 2026 eBay listings for new 64-oz complete kits ranged from $25.99 plus $10.00 shipping to $47.99 plus $7.99 shipping, and the official County Line site does not expose a fixed manufacturer-direct USD checkout price.
