Keurig specializes in manufacturing one cup coffee machines. It seems like they are synonymous to single brewers which is why when you ask for suggestions as to which coffee maker brand is best in this, you will hear the name Keurig pop out.
One of their innovations is the K-cups technology. Most of their brewers use K-cups so you cannot use any other coffee grounds or pods. If you want to purchase a Keurig single cup machine, be prepared to purchase the K-cups.
The coffee grounds are sealed in the cups. You will only need to prick the lid of the cups to release the grounds inside so the brewer can better extract essential oils and flavour from it. This is a convenient method because it lessens cleaning time. You only need to dispose the K-cups after using it K cup filling sealing machine.
The downside is, the limitation of flavour. Unlike other brewers that use coffee grounds, you cannot easily tweak its taste. If you feel like the taste is kind of mild for your taste, you cannot just add a few more teaspoons of coffee. The K-cups have already been pre-measured. If you are a strong coffee drinker, this may be letdown.
However, you can always go for the B50 or B60 machine models of Keurig Company. These models can allow you to use brewing volumes up to 5.25 ounce. This is already quite good for those who have a need for strong coffee taste. The only downside to this is that it will produce less coffee.
If you are using the other sizes of brewing machines from this company, a highly suggested alternative to achieve a stronger flavour of coffee is to buy the Extra Bold K-cups. They also sell this in the market along with the other sizes of K-cups.
Another alternative is to purchase some helpful accessories such as the K-cup reusable filter. It is not premeasured. You will do the measuring of coffee grounds yourself so you can fill it up to the brim to achieve the strong taste you want. I think this is the best one because it will also not limit your gourmet coffee options. You can use any other coffee grounds. The Extra Bold cups can be difficult to find.
Choose any of these alternatives if you want to make the coffee your Keurig brewer produces a lot stronger. It worked well for other people so it should work for you too.
