Making Coffee at Home: Vacuum Canisters Revisited

My new Soulhand vacuum canister, complete with coffee beans, looking very pretty in the sun. Please don't store it in direct sunlight though!Welcome to the latest instalment in my Making Coffee at Home series, which takes another look at storing coffee beans in vacuum canisters. At the start of the year, I received the gift of a vacuum canister from Soulhand (a company which also gifted me a gooseneck kettle the year before). Vacuum canisters, as the name suggests, work by removing (almost) all the air from the canister, which, in theory, keeps coffee fresh for longer than storing it in an airtight container.

My initial post about the Soulhand vacuum canister was written not long after I received it. I covered the principles behind vacuum canisters and the Soulhand vacuum canister itself, including what it was like to use. I also did some simple comparisons between beans that were stored in the canister and those kept in an airtight container (my usual practice for storing beans). Unfortunately, the results were inconclusive, largely because over the short timescales involved (a week), I wouldn’t have expected the coffee to go stale. However, at the end of the post, I explained that I’d set up an experiment to see what difference storing beans in a vacuum canister makes over a longer period of time…

Making Coffee at Home: Soulhand Vacuum Canister

My new Soulhand vacuum canister, complete with coffee beans, looking very pretty in the sun. Please don't store it in direct sunlight though!Welcome to the latest instalment in my Making Coffee at Home series, which is all about storing coffee beans at home. Other than a post about keeping coffee beans in the freezer, it’s not something that I’ve written much about. Coffee’s twin enemies, when it comes to freshness, are air and light, so the standard advice, once you have opened a bag of coffee, is to store the beans in an airtight container away from directly sunlight.

Typically, I’ll put around 80 grams of beans into an airtight container, storing the rest in the original bag (which, if it’s not resealable, I’ll pop into a larger container) in the cupboard. This means I’m not exposing the bulk of the coffee to fresh air every time I open the bag/container.

However, there is an alternative, which prompted me to the write this post. A couple of weeks ago, the folks at Soulhand offered me a vacuum canister. It’s something I’ve been thinking about getting for a while, so naturally, I jumped at the chance. Vacuum canisters, as the name suggests, work by removing (almost) all the air from the canister, which, in theory keeps the coffee fresh for longer.

Making Coffee at Home: Cloth Filters

Using my two-cup CoffeeSock cloth filter to make a pour-over in a white ceramic pour-over filter.When I first made coffee at home, over 25 years ago, I used a cheap filter machine, but I didn’t like the taste its metal filter imparted to the coffee, so I switched to the cafetiere and never looked back. Years later, when I started experimenting with home pour-over and other methods such as the Clever Dripper, I naturally used paper filters (I’ve had the occasional metal filter but never got on with them).

For several years, I’ve toyed with getting cloth filters to use at home. However, inertia and a general sense that they were a bit of a faff compared to paper filters put me off (which is odd, since many of the other little rituals around making coffee don’t bother me). Then, on my last trip to see Amanda in November, we were in GoGo Refill, a low-waste store in South Portland, where I saw some cloth filters from CoffeeSock.

To cut a long story short, I bought a pair, one for a Chemex and one for a standard two-cup ridge-bottom filter (like my collapsible travel filter). After using them on and off for the last two months, I thought it was time to share my thoughts.

Making Coffee at Home: Manual vs Electric Grinders

Amanda's Baratza Encore electric burr grinder next to my Aergrind hand burr grinder (not to scale). But which one did I prefer?One of the first pieces I wrote for my Making Coffee at Home series in early 2020 was on the importance of grinding coffee at home. Every now and then people ask me for advice on what sort of coffee grinder they should buy and while the article has some general advice (always get a burr grinder), I stumble over the question of whether to recommend a manual or electric burr grinder.

Regular readers will know that I have a soft spot for manual coffee grinders. After all, I own three of them: a pair of Feldgrinds and an Aergrind, all from Knock. I do have an electric burr grinder, but this is built into my Sage Barista Express. In theory, I could use it for grinding for filter coffee as well, but in practice, I use it exclusively for espresso, sticking to my Feldgrind for my daily cafetiere, pour-over and AeroPress.

However, when I was visiting Amanda last November, I had the chance to use her Baratza Encore for an extended period of time. This allowed me to make a direct comparison between electric (the Encore) and manual (my Aergrind) grinders as I made our morning cafetieres and daily pour-overs.
