A. Let’s find out why arabica coffee taste sour

In essence, coffee is a fruit with a specific pH content. Each coffee variety has a different pH, explaining why Arabica coffee has a sour flavour versus Robusta coffee.

Furthermore, processing coffee fermentation which is a fantastic fruit yeast that contributes to arabica coffee’s acidity.

Arabica coffee has a gentle taste of fruit, and it is always chosen as the significant coffee drink by coffee enthusiasts worldwide.
Robusta being cost efficient, is black and bitter and is more prevalent in Asia.

The caffeine content in arabica is lower than that of robusta, the sugar content is higher, arabica coffee is always favour by people who need to make coffee early in the day to stay alert. Arabica coffee is chosen as brew choice, such as cold brew iced coffee, tropical coffee, and fruit refreshments.

B. Distinguishing different types of arabica coffee

Arabica coffee beans belong to the tea coffee family, with short leaves, round and flat seeds, and a superficial porosity to crush after roasted. Because arabica has a high-fat content, a layer of glossy oil will develop when roast on medium, or a lovely, thick caramel layer will appear if you brew the espresso right and sip a cup of rustic arabica will reveal more fat than robusta.

Drinking an original cup of arabica is similar to biting into a fruit, with the high-pitched sour taste coming first, thereafter the bitter taste, and ultimately the fruity sweetness. This allure is what allows arabica to win over even the most discerning coffee lovers.

C. Possible reasons why your coffee tastes sour
& how to fix it

You are looking forward to your cup of coffee but the coffee tastes sour!
We tell you possible reasons why your coffee tastes sour and how you can fix it.

1. The coffee is not fresh brew or make too much

Coffee tastes sour if you let it sit too long after brewing. This often happens when you brew too much coffee at once.
You want to calculate how many grams of coffee you need for two, three,… cups of coffee? Follow the rule of thumb for coffee preparation: 10g to 150ml of water!

You can individually calculate how much coffee you want to prepare – for e.g. 15g of coffee to 225ml of water.

2. Incorrect grinding size (Too fine or too coarse)

If the grind is too coarse, coffee can taste sour or watery because the coffee is under-extracted. Under-extraction results in primarily the acids releases out from the coffee, rather than the bitter compounds.

If the grind is too fine, coffee can taste bitter and hollow, coffee will over-extract. Bitter compounds will muffle the fruit acids and sugar composites.

3. The brewing temperature of the water is too low (below 90°C).

The ideal temperature for your coffee water is 91°C – 96°C for most brewing methods.
If your water is lower than 90°C, the coffee will taste watery to sour. Depending on the temperature of the water, different flavours will release from the coffee.

Therefore, we recommend that you let boiling water to cool down for 10 seconds or transfer it to a goose neck kettle immediately after boiling.

4. The coffee roast level is too light for your taste

The coffee was roasted too light for your taste. Some Arabica varieties taste fruitier than others. If these are done roasted light, the natural fruit acids are not completely broken down.

If you don’t like this, try a milder coffee. Like our Brazilian coffee, which tastes wonderfully mid-bodied and reminiscent of the taste of chocolate.

5. The coffee roasting process need to be done gently

The coffee roasting is too hot. This often happens with “hot air“ roasting, where the coffee is shock-roast at high temperatures for a short time. Thus, the coffee bean almost chars from the outside while the acids inside are not completely broken down.
When brewing the coffee, these acids subsequently escape to the outside, which can lead to a sour taste.

We micro-batch roast all of our coffees using a gentle drum roasting process, so our coffees taste wonderfully consistent, mild and flavourful.
