What customers say

In the morning nothing is better than a cup of freshly roasted coffee from Gigawatt Coffee Roasters! Everything about my experience has been amazing! The ordering process and website is easy to navigate. My order shipped the same day and arrived to my home in Nebraska 2 days later. I ordered the Super Sampler pack.

I must admit that I’ve been a coffee snob for more than fifty years. I know a great coffee bean. Over the many years I’ve come across coffee that has been inconsistent in flavor and quality. Until I came across “GIGAWATT COFFEE ROASTERS” at my local farmers market.

Love these beans! Enjoying "live wire" lattes this morning. Great roast. My regular favorite is "wahgi valley kimuga" for drip. The pineapple even comes through. It all adds up; good pricing, good selection, 5 bucks to ship, fast delivery - Gigawatt is tough to beat!

I am loving the whole bean live wire espresso blend. I use it in my Keurig and in my regular coffee pot at work also. Anxiously awaiting the cold brew! I plan on keeping a few of them in the side bags on my motorcycle. So I don't have to drink gas station coffee ;)
