A knock box is an espresso accessory that goes quite simple on the eye, but choosing the right one can boost your brewing experience manifolds. Many users consider Dreamfarm Grindenstein as the best espresso knock box right now on the market. We took an in-depth look into that claim and also discussed some potential alternatives.
Why Use A Knock Box?
A knock box could be an investment worth making for the following reasons-
- It Keeps The Portafilter Safe: When you try to expel the puck from the portafilter into your trash can, you would have to bang it against the palm of your hand or the side of your garbage bin to make sure all of it comes out. Doing so, there’s always a risk of damaging your portafilter and the trash can. If you use a dedicated knock box, it will effortlessly collect all the waste and keep your portafilter unharmed.
- To Avoid Odor Buildup: Wasted coffee grounds emanate an unpleasant smell. If you throw them in your trash can, the smell will disperse all over your place. Even when you clear out the trash, the odor might persist. A knock box traps the bad smell while storing old coffee grounds.
- You Can Store Old Coffee Grounds For Gardening: Old coffee grounds can be a rich fertilizer option for your garden beds. Knock boxes give you ample storage space for holding the residual coffee grounds so that you can later transfer them to a compost bin.
- Inexpensive and Easy to Maintain: Knock boxes are fairly low price espresso accessories, and they require minimal maintenance. Yes, you do need to wash them every once in a while. But, they are very easy to clean, so you don’t need to give it much effort.
Espresso Box Buyer’s Guide
Cost and Durability
Finding the right balance between cost and durability is important when you are looking for an espresso box, aka a knock box to buy. You can buy some of these boxes for as much as $20, while some could cost you more than $50. Now the question is, how much money should you spend on a box that serves as a dedicated waste bin for your expired coffee grounds?
You might come to think, what’s the difference? A plastic made knock box would be just as good to hold coffee waste as a fancier stainless steel one? While that line of thinking is not completely flawed, you should still consider the durability of the box. No matter how cheap a box is, what’s the point in saving the money if you need to buy another one a few days later?
Grindenstein knock boxes are a clear winner in this regard. It has an ABS plastic made casing, but the interior is fortified with a stainless steel core. This gives you the best of both worlds-the plastic shell makes the box economical and lighter, while the stainless steel core gives the box the sturdiness you desire.
What size of knock box should you go for? The answer to this question relies on your capacity demand and space preference. Some of us like to keep our kitchen counters as hassle-free as possible. An oversized knock box could compromise your efficiency and prompt you to reconsider your decision to buy a knock box.
If you happen to make a lot of coffee every day, then you should look for a larger knock box. However, if you don’t mind frequently unloading and washing it, then a smaller knock box would be just fine.
You need to ask yourself what tops your priority. If you feel like a larger knock box feels too imposing, then it’s an absolute no-no for you, but if you don’t want to go through the trouble of regular maintenance, then a bigger knock box is the perfect match for you.
In a professional setup, larger knock boxes are mandatory. You won’t have the time to empty it and then preparing it for further use during open hours. If you want to use old coffee grounds as fertilizers, then a large knock box would be quite helpful.
A comprehensive stainless steel build would make the knock box remarkably strong. But, it does come with its drawbacks. Full metal body boxes are more expensive, and they are bulkier than others. A plastic build, on the other hand, makes the unit more affordable, but it becomes rather flimsy for prolonged use.
Dreamfarm Grindenstein boxes offer you something in between. It features a plastic exterior with a stainless steel core inside. This keeps the price reasonable, and also makes the box fairly strong.
