I've just started drinking home made coffee what do you suggest I experiment with next?

I love Starbucks beans, the dark roasts like Cafe Verona, Sumatra, etc.

Tea.

Hey, you asked.

What @marinelife said. Sumatra.
If you have access to it, try Peet’s.
And if you have a local roaster, buy some freshly-roasted whole beans and a grinder for a much better experience.

We like the Starbucks Espresso Roast beans in our regular coffee maker.

I would definitely try some teas like Earl Grey, Darjeeling and Lapsang Souchang. Coffee is nice, but is pretty similar in flavors, whereas teas run the whole gamut of flavors.

If you decide to get really crazy, you might want to try some Korean Barley Tea

My husband loves Starbuck’s medium roast Colombian flavor and regular Dunkin Donuts. I try to buy it on sale, because it can be two of the pricier in the grocery store.

Get some green beans and roast them yourself.

Are there any little shops that roast beans near you? If so try those.

Trader Joe’s has excellent coffee for ½ the Starbucks price (again, if they are located near you).

I have a few friends who really like Dunkin Donuts beans (you mentioned Tim’s, I dunno if they have Dunkin Donuts in Canada).

A great big fresh orange. A natural pick me up
