Summer Coffee Mistakes (And How to Avoid Them)  

With such warm weather, our coffee habits often need a little adjustment. What works perfectly in winter can fall flat in summer, leaving you with watery drinks, bitter flavours, or coffee that just doesn’t hit the spot. The good news? A few simple tweaks can make all the difference, to keep you flowing in the new year.


Here are some common summer coffee mistakes & how to avoid them.

Mistake #1: Pouring Hot Coffee Over Ice    

It seems logical, but pouring hot coffee straight over ice usually results in a watered-down, bitter drink. The ice melts instantly, diluting the coffee before it has a chance to shine.

How to avoid it: Brew your coffee stronger than usual if you’re icing it, or switch to cold brew. Cold brew is made using cold water over a longer time, resulting in a smoother, less acidic flavour that’s perfect for summer.

Mistake #2: Using the Wrong Beans for Iced Coffee  

It seems logical, but pouring hot coffee straight over ice usually results in a watered-down, bitter drink. The ice melts instantly, diluting the coffee before it has a chance to shine.

How to avoid it: Brew your coffee stronger than usual if you’re icing it, or switch to cold brew. Cold brew is made using cold water over a longer time, resulting in a smoother, less acidic flavour that’s perfect for summer.

Mistake #3: Storing Beans Incorrectly in Hot Weather  

Heat and humidity are coffee’s worst enemies. Leaving beans near the stove, in direct sunlight, or in the fridge can cause them to stale faster and absorb unwanted moisture or odours.

How to avoid it: Store your coffee beans in an airtight container in a cool, dark cupboard. Avoid the fridge as it introduces moisture and temperature changes that impact flavour.

Mistake #4: Forgetting to Balance Coffee and Hydration  

Coffee is part of many people’s daily routine, but in summer it’s easy to forget that hydration still matters, especially on hot days.

How to avoid it: Enjoy your coffee, but balance it with plenty of water throughout the day. A simple rule of thumb is to drink a glass of water alongside your coffee to keep things flowing.

Mistake #5: Using Old Ice  

Ice made from tap water or stored for long periods can pick up freezer smells, which transfer straight into your coffee.

How to avoid it: Use fresh ice made from filtered or spring water for the cleanest taste. It makes a noticeable difference, especially in iced lattes and espresso tonics.

Mistake #6: Overcomplicating It  

Summer coffee doesn’t need to be fancy. Trying too many syrups, flavours, or techniques can overwhelm the coffee itself.

How to avoid it: Keep it simple. Quality beans, clean water, good ice, and the right brew method go a long way.

With a few small changes, your summer coffee can be just as satisfying as your winter cup, if not better. Using quality Flowspresso beans and adjusting your brewing style means you’ll enjoy smooth, refreshing coffee all season long.

Because great coffee shouldn’t take a summer break.
