Brewing coffee is not like throwing coins in a fountain. Wishes don’t come true from tossing random things in the pot. Keep to the ration and reap the rewards.
Make sure your grind is on point for the type of brew you’re making. It really will affect the taste. The proper grind allows all of the flavors of the roast to end up in your cup, without any bitterness. So know your grind.
If you start with funky water it’s no surprise the coffee will be too. Keep it fresh. Keep it filtered.
Like a wise coffee connoisseur once said, “Airtight keeps it right.” So seal that bag with gusto and make sure to keep the beans away from heat and moisture. That means just saying no to the freezer. You’ll need to use it within a week of opening but your tastebuds will thank you.
