💧 Tip: Check Soil Moisture Before Watering
Push your finger 2 inches into the soil near the plant base. If it feels dry, it’s time to water. Consistent moisture — not soggy soil — prevents blossom end rot and cracking.
⏰ Tip: Water in the Morning
Always water tomatoes in the early morning (6–9 AM). This gives leaves time to dry before evening, reducing fungal disease risk. Drip irrigation at the base is ideal — avoid wetting foliage.

 

Tomato Water is simply that clear liquid that spills from ripe Tomatoes. It has strong taste of summer, like the whole garden would be bottled. That shining red vegetable turns into something nice and unexpected: a clearly distinct liquid full of strong Tomato smell despite its modest origin.

To prepare Tomato Water, we can not imagine a simpler way. Take very ripe Tomatoes chop them and mix with a bit of salt. Lay big cloth, cover it by means of cheese cloth and set above a bowl.

What Is Tomato Water and How to Make It

Pour the chopped Tomatoes in it and leave to drain slowly for some hours, the gathered liquid will be your Tomato Water. Want another method? Mix the Tomatoes and press the mix through a coffee filter instead.

Whatever way you choose, what passes through it will be pure Tomato Water.

Wet cheese cloth or kitchen paper towels work well for filtering Tomato pulp also. Leave it stand in the refrigerator for best results. From almost two pounds of ripe Tomatoes, you will receive around eight units of clear Tomato Watre.

Big Tomatoes beat cherry or grape kinds. They must be truly juicy and mature… Heavy, a bit soft to touch when you hold one of them.

There is a fermented method if you want to try it. Chop little Tomatoes in quarters, bigger in eighths. Let them ferment for around a week in room temperature.

Later filter in the refrigerator to release the Tomato Water. The main rule? Do not press the pulp during the screening.

Tomato Water has endless uses. It shines in cocktails, as sparkling Water from it, or in salty dressings. Bread, sauces and baked goods all benefit from it.

As cooking liquid, it served well as a veggie replacement four stock in soups and risottos. Add it to stews and soups when you want richer taste. The final product gives ultra-clear colour and strong Tomato sign, with tender traces of basil and garlic running through it.

Keep Tomato Water in little portions and it will be ready anytime. No more need to wait for Tomato season. There is even a gin called Covalle Tomato-Aquatic Gin, that captures the peak season freshness of garden by means of a special method to switch smells and keep the tender green note of the fruit.

On its own, Tomato Water does make a genuinely funnydrink. It smells well, like a Sangria Mary, but served nice in a martini glass.
