Show me some cocktails I can take to a festival, with no access to a cooler, stored in drinks pouches.

For a festival scenario where you won’t have access to a cooler and will be storing your drinks in pouches, you'll want cocktails that maintain their great flavors without the need for temperature control. Here are some options based on the information provided:

1. Long Peach Iced Tea is a fantastic choice when looking for a blend that's quite resilient to temp changes. Even though it’s usually served cold, the combination of Peach Schnapps, Gin, White Rum, Tequila, Triple Sec, and Lemon Juice, topped up with Lemonade, will hold up well in a pouch. This cocktail brings a lovely fruity and spirited experience ideal for those long festival days.

2. Moonjuice is also a great option for pouches, particularly because it’s designed to be a shareable drink often served in larger quantities. Made with Vodka, Peach Schnapps, Orange Juice, White Rum, Lemonade, and Blackcurrant Cordial, its layered flavors remain appealing even without a cooler. Its fizzy and fruit-forward profile will stay enjoyable throughout the day.

3. Key West Cooler fits the vibe of a festival perfectly. Containing Coconut Rum, Vodka, Peach Schnapps, Orange Juice, Cranberry Juice, and Melon Liqueur, this cocktail bursts with tropical flavors. The alcohol content and fruity notes make it durable in varying temperatures while still delivering a refreshing taste reminiscent of lazy sunny days.

4. Summer Cooler is a wonderfully simple yet delicious combination of Orange Juice, Cranberry Juice, and Amaretto. Even though it's best when chilled, its inherent sweetness and tart flavors from the juices and the almond liqueur will still taste delightful as the day goes on. Plus, it’s typically prepared in larger quantities, perfect for filling multiple pouches.

These cocktails can be pre-mixed and stored in pouches to ensure you have a flavorful and enjoyable beverage on hand while soaking in the festival's atmosphere. Enjoy your festivity responsibly!
