My Favorite Coffee!!!

EviAugust 17, 2025

Wow! Good A$$ coffee! I love-LOVE the taste of it, nice dark coffee with chocolate undertones and I love that it’s easy on the stomach because since turning 40 I noticed my stomach being upset after drinking regular coffee-and right after receiving a Nespresso virtue next machine for my birthday! So I’ve been on the hunt trying to find a good coffee since. I went from VitaCup low acid-which I thought was really good but not great to Everyday Dose-which I like but I miss the ritual of brewing and smelling the coffee so I didn’t like that-also kind of smelled like chicken stock when I mixed it up which totally turned me off so didn’t like that too much! Especially in the morning! And now I’m on to this one-the taste is great-I get that weird engergy like EveryDay Dose which I like-and it’s easy on the stomach! So far this is my FAVORITE coffee! I have ADHD and it’s like taking the medication for it-helps me focus and gives me energy and my mind isn’t all over the place when I drink it-definitely recommend! Also I brewed it thru my Nespresso Virtue Next using one of those silicone lids which work amazing! Read more

Must try

Ray DigiaimoDecember 5, 2025

I recently tried lion’s mane coffee, and it’s quickly become part of my daily routine. The flavor is smooth and slightly earthy, but still tastes like real coffee—not bitter or “mushroomy.” What stood out most was how it made me feel: within about 20–30 minutes, I noticed a gentle lift in mental clarity and focus without the jittery feeling regular coffee sometimes gives me. After drinking it consistently, I’ve felt more productive in the mornings, and even my afternoon energy slumps seem lighter. It also feels easier to stay focused on tasks without getting distracted. Overall, lion’s mane coffee has been a surprisingly enjoyable blend of good flavor and noticeable cognitive benefits. I’d recommend it to anyone looking to enhance their coffee routine with something that supports brain health. Read more

Clogging machine

Lex MonteDecember 21, 2025

I love the flavor and minimal acidity of this coffee but since the blend is milled very fine, my coffee machine constantly gets clogged. I had to stop buying these :/ Read more
