Please can anyone recommend ground coffee?

Sorry Douwe Egberts, Costa, and Sainsbury's House Blend are generic vanilla, sub-standard coffee which sometimes blend sub-par Robusta Beans to adjust strength. Unfortunately it's difficult to suggest Arabica Coffee that would suit your tastes without knowing your preferences. Usually though the Americas are deeper roasted (Arabica) beans for those that like Strong, Chocolately tasting coffees. For those that like a mellow, nuttier, sweeter taste most go towards Ethopia or Kenyan Coffees (which are roasted less) but the issue is the quality has dropped dramatically in the past few years. My preference is Rwandan coffee (which is currently 2 for £5 in Waitrose) which is similar in taste to most most African Coffees, but has a far higher QA.

Probably not one for the coffee aficionados but I find the ground coffee and coffee beans from Aldi are pretty good! (Alcafe brand) - the cheapest out the lot in this thread, and not rank. (Not Alcafe House Blend ground - which isn't bad - but the ones that have the strength on the packet, numbered, are better. Aldi's website doesn't show the full range). Ground coffee, here

3 - House Blend (at least, it is for the Coffee Beans)
4 - Italian Blend
5 - French Blend

Lidl's Deluxe ground coffee is more expensive but often on their weekend offers. Example, here (edited)

I have Aldi own brand ground - No3 Colombian- and really like it. To me it compares favourably with the Taylors decaf that I also have

Starbucks.

Lavazza Rossa is my favourite

Lavazza Rossa and an aeropress, can't go wrong.
Will give you a cuppa that puts most machines to shame.

The best thing we did was change from Gold Blend to a bean to cup machine , even the cheapest beans taste better than instant. We drink a lot of coffee so it was worth the investment in the machine and actually using beans works out much cheaper than buying instant for us. If you have 4 or more cups of coffee a day a bean to cup is worth considering. Our latest Machine was a Delonghi manufacture refurbished one bought off eBay during one of the 20% off promotions , making it half the usual price and you wouldn't know it wasn't new.

Starbucks house blend, pike place and blonde roast, also Costa mocha italia & dark amazonian blends. On offer costa is usually £2.50 whereas Starbucks on offer is £3, well worth the money IMO.

Thank you all, very much appreciated

Douwe Egberts instant coffee is the best and as good as some ground coffee. For coffee beans (when I can be bothered) I like ALDI's house blend, (edited)

I use asda organic Nicaraguan ground coffee.

Coffee beans at ALDI, I find the Italian blend too weak, the Colombian too strong, and gives me a headache after a few cups, but the house blend is just right.

Coffee is really down to personal taste so difficult to recommend. M&S pretty good, even their Italian under £3 is decent, as are Sainsburys. Aldi some good some very bad (Columbian tasted like dirt)
