It is unsafe to grind wet coffee beans in a grinder because wet beans will grind unevenly and clog the grinder. It will also introduce liquid into an otherwise dry area, promoting mold growth. However, a tiny amount of water added to the hopper can improve the grind and eliminate static cling.
Expensive coffee beans are worth it. They make a much better cup of coffee. You get a robust and full-bodied flavor and a delicious aroma. If you want exceptional coffee, it’s worth spending more on pricey beans.
You can unblock a portafilter basket by soaking the basket in vinegar, burning the coffee grounds off, scrubbing it with a brush, or even using the steam wand to push the coffee particles out of the filter.
Espresso cups are so small primarily because the beverage is very concentrated in comparison to brewed coffee. The cup’s size preserves the espresso’s flavor and discourages you from taking big gulps, as espresso is meant to be sipped.
Many coffee mugs are left-handed because most people are right-handed. If this sounds counterintuitive, it’s not. Instead, left-handed mugs allow all the “righties” in the world to do other tasks while holding tight to their morning brew.
Instant coffee can taste bitter because of the way you made the brew. The type of bean, drying process, and roast level can all cause a bitter taste. It could also be a user error. The type and temperature of the water and the ratio used can make coffee more bitter.
Coffee tumblers typically last around a year if they’re made of high-quality materials. If made of lower quality material, such as plastic, you can expect them only to last a few months.
Coffee grinders make a lot of noise because the coffee beans require a lot of force to grind due to their hardness. The spinning blades in conventional coffee grinders cause the beans to bounce around – the resultant sound of the beans being crushed can be harsh on the ears.
Percolators that have automatic shut-off features use a temperature gauge to know when to stop. However, not all percolators have these features, and manual percolators need to be stopped manually. Check if your percolator is electric or not to find out whether it will stop on its own.
Starbucks Coffee beans will typically last around three years if stored unopened in the freezer, nine months if unopened outside the freezer, or six months if opened. However, your coffee beans taste better the sooner you use them. Try to consume them within two weeks.
