coffee bean storage for home use
I have fond childhood memories of my mother yelling at me to close that bag of potato chips when you’re done! Now as a parent, I continue the tradition and yell the same advice to my children. There are two lessons to be learnt from this: listen to your mother, and fresh food tastes better.
After purchase, most people store their coffee in the same bags it came in. Those types of bags range from Earth unfriendly plastic to more eco-conscious paper. More fastidious individuals, on the other hand, take the time to transfer their beans into sealed airtight containers. Regardless of the environmental impact, all of these techniques suffer from the same shortcoming.
Repeatedly opening and closing a bag or container exposes the coffee to outside air, which in turn results in oxidation and staleness. When you’ve just spent $19 for a pound of freshly roasted beans, there’s nothing more frustrating than discovering your coffee is prematurely stale or past its peak.
We created the Bean Cellar as a specially designed single dose container for storing whole coffee beans. Now when you buy beans, you only have to take out your scale once to weigh doses of your favorite coffee. It does make a big difference it terms of convenience by not having to take out a bag, scale and dosing cup every time you want to grind a shot. And by portioning your beans in a single sitting, you expose your coffee to air only two times, first when you open your bag and finally right before you grind.
Bean Cellar – Glass
We offer two types of Bean Cellars, one for the home and the other for commercial use. The home Bean Cellars use 2.5mm extra thick, Japanese high borosilicate glass tubes, making them especially tough and shatter resistant. The caps are precision CNC machined aluminum and finished with a protective anodized surface. To create airtight seals, instead of cheap silicone, we use Viton O-rings which offer extended wear resistance and stability under the harshest conditions. And most importantly, we’ve incorporated a one-way valve into the cap of every Bean Cellar.
After roasting, fresh coffee outgasses CO2 which has to be vented from the storage container. Recessed into the cap of every Bean Cellar is a custom one way silicone dome valve which releases internal pressure. The stored coffee remains blanketed in a heavier layer of accumulated CO2 which upwardly displaces any residual air introduced during the filling process.
The home version of the Bean Cellar comes in two different sizes, and are named Shorty and Tall Boy. Shorty is 130mm and Tall Boy 150mm long, both models have an outside diameter of 30mm. On average, Shorty is designed to hold up to 18 to 19g of beans or 48.9cm3 while Tall Boy can fit 23 to 24g or 59.7cm3. Capacity will vary and depends on the type of coffee bean being stored. If in doubt, weigh out a dose of your favorite coffee beans and measure the volume using a graduated cylinder or similar device.
With any glass manufacturing where the item is either hand blown, machine extruded or blow molded there is going to be variation in the dimensions. The tops and bottoms of our tubes are cut and sealed while still molten, which provide variation in size and shape as well. This is the nature of the medium rather than any defect in the product.
Just about every glass product produced that is not machined will have these subtle differences. Every glass product is like this from even the most renowned manufactures.
Shorty and Tall Boy Bean Cellars are sold in lots of 12 and include a custom designed wooden storage caddy as well as a useful stainless steel funnel. Each Caddy is hand made and cut from solid dark walnut hardwood. The Caddys are individually sanded and finished with a natural linseed oil resulting in a very light glossy finish. Regular applications of linseed or mineral oil will help to preserve the original finish.
While the holes in the caddy are CNC machined to a precise dimension, you might notice some variation in the depths. The grain of the wood and subtle contractions due to changes in weather and humidity will affect the sizes slightly.
While the Bean Cellars are made of a tough durable glass, they still can be broken. We recommend using common sense when handling the tubes, taking care not to drop and avoiding sudden impacts.
Removing the Cap
Place your thumb against the side of the cap as shown in the illustration below.
Applying steady pressure, push the cap upwards and away from your hand. Do not apply excessive force as the cap my suddenly loosen and fly off the tube. For the first few times, we recommend using two hands till you become more accustomed to the amount of force necessary to remove the cap.
We recommend removing the caps from all of the Bean Cellars prior to filling. Keep the glass tubes inside the caddy. Weight or portion your beans in another receptacle and then use the included funnel to fill each tube.
Care & Maintenance
The glass tubes are dishwasher safe. The caps are anodized aluminum and should only be wiped with a damp towel. They are not dishwasher safe, and abrasive or strong cleansers will damage the surface.
A periodic oiling of the O-rings with a light mineral oil will keep the caps operating smoothly. We recommend using a very lightly saturated cloth or cotton swab for application.
