What Is Toast?

Toast: a soft, sweet, square-shaped bread. Compared with other kinds of bread, it is remarkably versatile. It can be the star of a meal, turned into all sorts of dishes for people to enjoy, or it can play a supporting role, lifting the quality and flavor of other ingredients.

Why Is FrontStreet Coffee Talking About Toast?

Why would FrontStreet Coffee, a coffee workshop, suddenly bring up toast? The reason is that many friends recently asked FrontStreet Coffee to recreate a rather unusual coffee drink made with toast: the White Toast Dirty.

Understanding White Toast Dirty

Do not misunderstand, though. Making it with toast does not mean adding toast to the Dirty; it means adding the aroma of toast. The method is very simple: replace the "milk" in the Dirty with "milk that has been soaked with toast." Although it is simple, it brings a double improvement to the milk in both aroma and texture. Soaking the toast gives the milk a bread aroma, and the texture becomes richer and smoother as well. Long ago in Western countries, people improved the flavor of poor-quality wine by soaking toast in it. So today FrontStreet Coffee is recreating and tasting this recently popular White Toast Dirty to see what it really tastes like.

An Important Safety Notice

But here is the thing: FrontStreet Coffee does not recommend that everyone casually try this at home. If it is not handled properly, this preparation carries certain safety risks. Fresh bread has a very short shelf life, and if it is not eaten in time it will grow mold and spoil. Soaked in milk for a long time, it spoils far faster still, because milk is rich in nutrients and makes a perfect breeding ground for bacteria and mold. So FrontStreet Coffee does not recommend easy replication, especially for anyone with a more sensitive stomach.

How to Make White Toast Dirty

First, choose a toast with a fairly rich aroma to give flavor to the milk. Here FrontStreet Coffee chose raw toast, made with butter, cream and other ingredients, which lends the milk more aroma and texture. For the soaking ratio, FrontStreet Coffee used 1:5, that is bread 1 and milk 5. This ratio is not too large, because the toast absorbs some milk as it soaks and the final amount of milk you get will be less than what you poured in, so add a little extra milk to make sure you have enough for a full cup of Dirty.

Preparation Steps

The steps are very simple. First take a sterilized sealed jar, tear the toast into pieces and put them inside. Then pour in the milk, seal it, and place it in the refrigerator to soak for 4 hours.

After 4 hours, take it out and strain out the bread crumbs with a sieve, and your toast milk is ready.

Making the Coffee

FrontStreet Coffee took a small taste and found it really does have a very obvious toasted-bread aroma, and the overall texture is richer than regular milk, somewhat like the texture of purified milk. Now take out the pre-chilled glass and start making the Dirty. Here FrontStreet Coffee uses 160 ml of milk and 40 ml of espresso.

This time FrontStreet Coffee used beans from its own selection, the FrontStreet Premium Blend, with nutty, chocolate and butter cookie flavors. Extraction parameters: 20 g of coffee grounds to extract 40 ml of coffee liquid in 30 seconds. Once the milk is ready, simply place the glass directly under the espresso outlet.

When the coffee reaches the target volume, stop the extraction, and a clearly layered White Toast Dirty is ready. Then, after a quick photo, FrontStreet Coffee began the tasting.

Tasting Experience

With the first big sip, you can clearly feel the warmth of the espresso and the coldness of the milk collide in your mouth, creating a strong sense of contrast. Then the flavor experience begins: the roasted aroma of the espresso and the wheat fragrance of the toast milk each reveal themselves before starting to blend, shifting from distinct and stimulating to gentle and balanced after they merge. After swallowing, there is an aftertaste similar to buttery chocolate bread, which is very pleasant.

The second sip still keeps a distinct contrast in temperature and flavor, but compared with the first, because the coffee and milk have integrated a little more, the stimulation and the sense of contrast are somewhat weaker, though still very enjoyable.

By the third sip, because there is not much coffee liquid left, the milk flavor takes the upper hand. More than coffee, it tastes like a glass of milk with wheat aroma and coffee flavor, but it is still very delicious. So that is FrontStreet Coffee's experience with the White Toast Dirty. Overall it is quite good, but as mentioned, because of certain safety risks, it is not recommended that everyone casually recreate it, especially anyone with a weaker digestive system.

FrontStreet Coffee Recommendation

For a Dirty, tools and materials matter as much as the recipe. The materials are the same as an iced latte, milk and espresso, with the only difference being that the latte gets ice and the Dirty does not, which is why a Dirty is often jokingly called an iced latte with the ice removed. To make a good one, choose a medium-dark blend or an SOE single origin, because they carry richer caramel aromas and a heavier body that stands up to the sweet milk and leaves a long finish.

For consistency and value, FrontStreet's Classic Blend is the go-to. It pairs a smooth Brazilian base with wild Mandheling and a small amount of Robusta, so the extraction gives rich, fine crema and deep layers of aroma, with a pronounced butter and roasted chestnut character in the Dirty. If you want the espresso itself to lead, the FrontStreet PWN Gold Mandheling as an SOE is exceptional: beans of screen size 18 and above, fewer than 3 defects per 300 g green sample, top G1 grade, and three rounds of manual selection for a clean cup, with medium-dark roasted caramel, dark chocolate and toasted bread notes that layer beautifully against cold milk. The FrontStreet Brazil Queen Estate SOE, a yellow bourbon, brings more natural sweetness and works well because the first sip hits the crema. And for a softer, fresher Dirty, the medium-roast FrontStreet Strawberry Candy Espresso layers rose, raisin and nut aromas over the milk, turning the drink toward cranberry cookie and hazelnut ice cream.
