Primula Burke Deluxe Cold Brew Coffee Maker

Primula Burke Cold Brew Iced Coffee Maker - Glass Carafe 1.6 Qt : To start, this maker does make decent coffee & the screw-off bottom of the filter insert allows for relatively easy clean up. My main complaint is the strength of the brew - it is ok, but not nearly as good as using a simple jar or French press approach that allows free mixing of water and ground coffee via occasional stirring. Without the ability to dilute, this maker just does not make enough coffee for me. The filter insert is the main impediment to more efficient brewing. Some small modifications that could push this maker to 4 or 5 stars: 1) The filter is too narrow. After putting 12-16 TBSP coffee into the insert, the bed of grounds becomes densely packed after adding water. The maker suggests stirring the grounds from time to time in order to make the coffee stronger, but the only way to avoid a packed bed of grounds is to add less coffee to the filter insert. 2) The screw-off filter bottom is not porous/does not have a membrane. This means that the brew mainly relies on left-right water diffusion (reducing brew efficiency). Additionally, the lack of a porous bottom means that there is about an inch of grounds/brewed coffee left in the insert (see pics). A porous bottom along with a way to rest the filter insert atop the brewer to drain prior to emptying spent grounds would help reduce waste. 3) Less important to me compared to 1) and 2): The filter does not remove finer grained coffee particulate. The filter is better than the results using a French press but if you want truly clear (but brown) coffee you will need to filter it. In the end this brewer requires a choice between coffee strength (number of servings) and brew efficiency (wasting coffee) and anything other than a lukewarm recommendation for this brewer does not seem appropriate for my needs. Still looking for that elusive easy-cleanup cold brew maker! *** just found the Toddy for concentrated cold brew.
