Acid-loving plants such as hydrangeas, rhododendrons and blueberries.

The amount of caffeine depends on the brewing method and the beans used. On average, a cup of filter coffee (120 ml) contains around 90–120 mg of caffeine, while an espresso (30 ml) contains about 60–80 mg.

In general, a double espresso or an Americano contains the most caffeine per serving. However, per millilitre, a ristretto is the strongest. Coffee made with a French press or percolator often contains more caffeine than standard filter coffee.

Robusta beans contain about twice as much caffeine as Arabica beans. So a blend with Robusta will have more caffeine than a 100% Arabica coffee.

According to the EFSA (European Food Safety Authority), up to 400 mg of caffeine per day is considered safe for adults. That’s about 5 cups of filter coffee.

No, decaf is not completely caffeine-free. A cup of decaf coffee usually still contains around 2–5 mg of caffeine, depending on how it’s processed.

No, that’s a common misconception! Light roast coffee beans often contain slightly more caffeine per gram than dark roast beans, as the longer roasting process slightly reduces caffeine levels.

A medium-coarse grind works best. A grind that’s too fine (like espresso) can make the coffee bitter and clog the percolator, while a grind that’s too coarse will result in weak coffee.

Medium to dark roasted coffee is ideal. These roasts provide a full, rich flavour that suits the percolator brewing method.

A good rule of thumb is 1 part ground coffee to 10 parts water. For example: for a 6-cup percolator, use about 30–35 grams of coffee and 300–350 ml of water.

No, but make sure the coffee isn’t ground too finely. Some brands offer pre-ground coffee for percolators, but you can also buy beans and grind them yourself to a medium-coarse consistency.

That depends on the model. Stainless steel percolators usually work on induction, while aluminium models typically don’t. Check if the base is magnetic or use an induction adapter.

Matcha is packed with antioxidants, amino acids and a small amount of caffeine. It gives you a gentle and steady energy boost without spikes, which makes it a popular choice for anyone looking for a healthier alternative to coffee.

Yes, you can enjoy matcha simply with water. The latte version is loved for its creamy texture, but without milk you’ll taste the pure flavour of matcha much more clearly.

Matcha can taste bitter if the water is too hot or if you're using a lower-quality powder. Stick to water around 80°C and choose a good-quality matcha for a smoother, more balanced taste.
