Scene: SH has been trying a new, local coffee roaster. It has taken only a few years for us to go from non-coffee drinkers to full-fledged coffee snobs. We started with the gateway coffee of Starbucks mocha, which is coffee-flavored hot chocolate with extra fat, and moved to ground coffee from the store and then from Costco to coffee beans and our own grinder to the glass beaker thingy and water heated in a special water heater. We got the beaker thing at a church youth group fundraiser, right about when our microwave started to die (and no, we have not dealt with that issue - we are working around it - people got along just fine for millennia without a microwave and we can do it for a year or two), so SH stopped in at Goodwill and picked up one of those plug-in water heaters. Not the immersion kind, but more of a plug-in teakettle, only not for brewing.
So he mastered the art of grinding the coffee while the water was heating and then carefully pouring the hot water over the grounds.
But then he tried this new coffee roaster and this new bean and the coffee was way too tannic so he tried different things - all kinds of stuff except just taking the bag of beans back to the store and telling them it was too tannic.
SH: How's the coffee been?
Me: OK, I guess. I haven't been paying attention.
SH: I've adjusted the grind.
SH: And tomorrow, I'll have my new water heater.
Me: What? You think money grows on trees?
SH: It goes to 190 degrees.
SH: I can't get the old one past 180.
Me: So? Just use a kettle and put it on the stove.
SH: No! Boiling is too hot!
