A List Of The MOST Sour Fruits

Share this post:

True fruit lovers will often not discriminate when it comes to the kind of fruits they buy and ultimately eat. This is because all fruits are nourishing, unique in their taste and shape and definitely healthy. However not all fruits are created equal and they can be divided in a myriad categories, if we really wanted to. But for starters it’s safe to say there are at least two categories available that will usually split people into two different camps: sour fruits and sweet fruits. 

Sour fruits have an entirely different composition that gives them that powerful and distinguishable taste among all the fruits. Of course, sourness can also be an indicator of fruits that have gone bad or that are in the process of going bad. This is why it’s best to know which fruits are sour by nature, so you don’t have any unpleasant surprises when you actually begin consuming them. In the same line of thought, not all sour fruits are created equal either – some of them are mildly sour, while others are so sour they will make your lips pucker. So what are the most sour fruits? Let’s see what the most sour fruits out there are and what makes each of them unique, in terms of health benefits and uses. Read the list of sour fruits we’ve prepared below, see which one you’ve tasted so far and which one sparks your interest the most:

1. Lemon/Lime

Both of these fruit types are acidic and sour, but their colors differ. Lemons are typically a bright yellow, while limes are green. Another important difference between them is that although both are sour in nature, lemons tend to lean towards the sweeter palate, while limes have a hint of bitterness to them. Having said this, limes are actually the most sour fruit in the world.
