## Summer Coffee Foundation

### Make a Cold Brew Batch

Cold brew is the backbone of most summer iced drinks.

- Coffee grounds (medium-coarse grind): 60g
- Cold water: 500ml
- Steep in refrigerator for 12–18 hours

Strain and store in a sealed bottle. Keeps refrigerated for up to 2 weeks.

## Recipe 1: Classic Iced Coffee

The simplest starting point.

- Cold brew: 150ml
- Ice: fill the glass
- Milk (optional): 30–50ml

## Recipe 2: Coffee Lemonade

Now a global café staple, especially popular in summer.

### Ingredients

- Cold brew or strong drip coffee: 100ml
- Lemonade (store-bought or homemade): 150ml
- Ice: to preference
- Lemon slice: for garnish

Fill a glass with ice, pour in the lemonade, then slowly pour coffee on top.


> 💡 **TIP**
>
> **Coffee lemonade tip**: Store-bought lemonade can be too sweet. Make your own with 30ml lemon juice + 20ml simple syrup + 100ml cold water — this lets you control the sweetness and tartness balance.


## Recipe 3: Coffee Tonic

Pour 80ml cold brew over 150ml tonic water. The carbonation and coffee bitterness are a natural pairing for hot weather.

## Recipe 4: Mint Coffee Frappe

A blended café-style drink you can make at home.

### Ingredients

- Cold brew or espresso: 100ml
- Milk: 100ml
- Ice: 1 cup
- Mint syrup or mint liqueur: 1 tbsp
- Whipped cream: for topping

Blend all ingredients, pour into a glass, and top with whipped cream.

## Recipe 5: Vanilla Coffee Float

Dessert-style coffee with a scoop of ice cream.

- Strong iced coffee: 200ml
- Vanilla ice cream: 1 scoop
- Ice: to preference

Pour iced coffee over ice, then place the ice cream scoop on top.

## Recipe 6: Watermelon Coffee Slush

An unexpected but effective pairing — watermelon's moisture works with cold brew.

- Frozen watermelon chunks: 150g
- Cold brew: 80ml
- Lime juice: 2 tsp

Blend together and serve immediately.

## Recipe 7: Matcha Coffee Latte

A Japanese-Western fusion combining green tea and coffee.

- Cold brew: 80ml
- Matcha powder: 1 tsp
- Oat milk: 100ml
- Honey: 1 tsp
- Ice: to preference

Dissolve matcha in a small amount of hot water, cool, then combine with the other ingredients.

## Recipe 8: Butterfly Pea Coffee

A color-changing visual showstopper.

### Ingredients

- Butterfly pea flower tea (chilled): 100ml
- Espresso: 30ml
- Ice: to preference

Pour ice and butterfly pea tea into a glass, then slowly add espresso on top. The blue-to-purple gradient effect appears as the layers mix.

> Ice dilutes any cold drink as it melts. Use 1.5–2x the normal coffee grounds when brewing, or use cold brew concentrate straight, to maintain flavor intensity from first sip to last.

- **Cold brew batch**: Prepare once, use all week across multiple drink styles
- **Coffee lemonade**: The new summer classic worth having in your repertoire
