We tried the Moccamaster and the amount of coffee recommended was nuts. From there went to Ratio. Really nice coffee but the thing has been repaired twice and now it is not functioning again. The backup for the Ratio is a Fellows. If it were up to me, I would do either a pour over or French press and not spend $$$ on an expensive coffee maker. Do buy freshly roasted beans, grind in a burr grinder and store beans in a vacuum canister.
Get a Mr. Coffee. Buy it at Walmart or in person to save over Amazon. I have two mocca masters, and two KitchenAid espresso machines (kf7). For coffee the mr. coffee taste good and is quick and easier to use than other ones. If you want to spring for the moccamaster probably wait for the amazon sale, think they have one in July or something? But black friday will also see about 100 taken off.
I was going to post this as well. It's such a non-issue with the lack of timer because it brews SO FAST.
I would remove the carafe for the beginning of the brew to allow more of an immersion brew, and reinsert/release the coffee after 3 or 4 minutes. The Zutto is literally half the size of the Moccamaster, so it makes sense that it would handle smaller amounts more easily. Obviously this is a hack because the KBGV is not designed for single cups.
Personally, I think the KBT is the best choice. It can brew 16oz and you can brew directly into a mug if you'd like. And when guests come over you can easily do the full 40 oz. I love my KBT, and I've read lots of mixed results with the KBGV.
It's actually the opposite of your concern. Actually, it's excels at brewing smaller amounts, while larger amounts (over 6 european cups) turn out over extracted. So it brews excellent coffee between 1/2 and 3/4ths (4-6 european cups). I don't bother with less than that, and more than that does tend to over extract, and taste suboptimal.
Another vote Moccamaster. Built like tanks. Produce excellent coffee. I’d spend the extra and get new but that’s just me.
Short answer - grind quality *absolutely* affects taste. What’s your budget ? A technovorm moccamaster and a Baratza encore is a great set up. Yes better to keep brewer and grinder separate - both for drip coffee and espresso.
Just checking you actually mean Americano - which is espresso and water added. I think however, you are looking for batch brew drip coffee, right ? Then a technovorm is the best option. Built like tanks. Will last ages.
