Does anyone have a moccamaster?

I just got one delivered this week because I had heard good things about it as a drip coffee maker. I’ve made coffee about 4 times in it now and I’m mostly getting sour, weak cups of coffee. The ratio of grinds to water I’m using is 60g to 1L water.

I’m using an OXO burr grinder and local beans (roasted within the last 2 weeks). I understand for coffee enthusiasts that my grinder is considered bottom of the barrel, but it’s what I’ve got. I’ve also seen that it might help to open up the grinds and give them a stir throughout the process. I’ve done this each time.

The instructions say to use a medium-course grind. I set my grinder on 8.5 to begin and the first batch was super sour. My understanding is that comes from under extracted beans, so I went incrementally finer.

Well today we landed on 7 on the grinder and it was so fine that a lot of the grounds made it through the filter. Was less sour though, so there’s that.

The obvious thing to change is trying different beans, but any other suggestions for what I could be doing wrong?

My parents have one, and have never had an issue. I'm thinking your ratios are far off. Do the same ratios you would do in a Mr Coffee.

FWIW, my dad purchases Dunkin' Donuts coffee grinds, and it comes out tasting better than actual DD store coffee.

Use a medium coarse grind should look like sea salt

I have one

I do 6oz of water to every 2 tbsp of grinds. My math says you are using too much water for 60g of coffee

I’ll use the scoop next time in place of the scale (although the scale should be more accurate), but I’m getting the ratios right off their website

Next, you’ll want the formula of water-to-coffee dialed in. The industry standard for optimal flavor is two tablespoons of coffee for every 6 oz of water – or 55 - 60 grams of ground coffee per liter. Click here for more details.

I should also add, I’ve got the “select” model. It has an extra switch on the front for a full carafe or a half carafe. I think this controls the flow rate of water.

That’s what I have

I know they rec the coarse grind for it so that’s what I use—pretty much a pour-over grind

I don’t get any bitterness. In fact it is the first coffeemaker where I have not experienced it

ETA: you may want to try soaking your paper filter before brewing—they can sometimes contribute to a bitter taste

I would just add a little more coffee or a little less water and see if that solves your issue

do the same ratio every morning

10 tbsp (not “heaping” but not flat either)
60 oz of water (I put a thin piece of tape to mark my fill line on the machine)

I have the select model as well. The switch alters the brewing speed and hot plate temp

I do this as well. The coffee is definitely sour and not bitter.

I’ll play around with the ratios and try some different beans. I really want to like this, but so far the results are not good.

Could it just be the beans? Might try a different brewing method to see if it's the beans.

This is probably where I should start. I’ve never tried these beans before, so it’s possible they’re just trash

I do 75g to 10 "cups" for a full pot. The grind should look like coarse sand. Look up images of moccamaster grind for clarification. I do use the moccamaster filters. I don't pre moisten the filters. I do gently stir as the brewing starts to saturate the grinds evenly. I never get any bitterness. When I first got mine I tried making the grind finer incrementally to try to extract more flavor and only succeeded in making the filter clog up and overflow. I have gotten a couple batches of beans that just would not grind properly or tasted off. I try to avoid dark roast as it's very oily and hard on my grinder.

I bought different beans today, so I’m going to start back at my original plan and see if it was just the beans. If not, I’ll keep messing with the ratios until I can make something work.

Might be the beans but that doesn't mean they're trash. Might be meant for a different extraction method like french press, pour over, etc.

I have had mine for about 6 years and use 60g per 1.25L water. When I fill the water all the way to the top I use 70g. I have a Baratza encore grinder set at 13 for most beans. If you are getting weak coffee I would grind your beans finer so the water takes longer to go through em.

Mine makes coffee almost as well as my Chemex.

Update: It was the beans

After thoroughly researching the issue, I thought I was following the instructions about as closely as I possibly could. So I decided to buy a new bag of beans from a different roaster and go back to my original plan.

It made a completely different (and much better!) cup of coffee. Where the first bag was sour and somewhat weak, this one felt rich and hit the right range of tasting notes.

I think I could still tweak it a bit to find that perfect cup, but I’m consistently making solid coffee with this thing now.
