Likewise, since Oxo recommends always brewing with water straight from a boiling kettle you don't have to fuss with thermometers or trying to hit an ideal brew temperature. Still, to ensure consistent quality I strongly suggest grinding beans the moment before brewing, weighing the coffee you intend to use, and processing them through a burr grinder to achieve a uniform grind size.
Performance and taste
I like to drink coffee that's packed with intense flavor, and lots of it. That's why for my test cups I used the highest recommended coffee ground dose (20 grams, 0.7 ounce) at the largest brewing volume the Oxo Good Grips Pour-Over manual suggests (360 mL, 12 ounces water).
I ground my test beans (Costco Colombian Supremo) with the $200 Oxo On Conical Burr Grinder since my usual go-to grinder, the $100 Capresso Infinity, is on its last leg. Oxo's grinder also boasts an integrated scale which automatically shuts the machine off at your target weight. The grind size I selected was one notch finer than the machine's middle setting.
Not counting the time it took to heat cool water to a boil (8 minutes or so) and fill the Pour-Over's reservoir, the gadget's actual brew time lasted about 2 minutes 30 seconds (give or take 5 seconds). After, the Good Grips always supplied a beverage which was big in flavor, rich, silky smooth, and filled with luxurious depth that lingered on my tongue. Not bad at all for a bag of bargain Costco java.
Refractometer readings confirmed what I was tasting. Each of my three official test batches had high TDS (Total Dissolved Solids) percentages between 1.4 and 1.5 percent. Their extraction percentages were also tightly clustered just outside the ideal range (23, 24, 23 percent).
For the record, the SCAA (Specialty Coffee Association of America) considers a "golden cup" of coffee to have an extraction percentage between 18 and 22 percent. While certainly operating within this spread, even SCAA certified coffee makers such as the Technivorm Moccamaster KBT 741 and Bonavita 1900TS weren't as consistent.
So, should you buy an Oxo Pour-Over?
If you love delicious drip coffee, then that's an emphatic yes. The brewing performance of the $16 Oxo Good Grips Pour-Over alone, backed up by countless anecdotal batches I made, places this little coffee funnel in the same heady league as the $299 Technivorm Moccamaster KBT 741 and $190 Bonavita 1900TS, both fully automatic drip machines.
I'll also wager that even experienced pour-over fans will appreciate how much easier the Good Grips is to use than other manual brewers from Melitta, Chemex, and Kalita. Of course, if you lack the patience to boil water separately or must have a massive carafe of coffee pronto (we've all been there), then the small batch size of the Good Grips Pour-Over won't cut it.
