Besides coffee and hard cider, my favorite way to stay hydrated is with Switchel, also known as Haymaker’s Punch. It is a heritage drink that farmers used to make to stay hydrated in the fields when swigging large amounts of water would just lead to an upset belly. Its affects are similar to sports drinks in that it provides hydration, sugars, and electrolytes. Ginger would help soothe the stomach, cider vinegar gives it a citrus bite, and maple syrup provides energy and taste.
Hannah’s Tonic aka Switchel
1/2 cup Maple Syrup
1/2 cup Cider Vinegar
1 tsp Ground Ginger
1/2 cup Lemon Juice (optional)
1-2 gallons Water
Add all ingredients to a shaker cup and mix. I then dilute with 1-2 gallons of water depending on how strong I am wanting the drink.
EDIT: As The Vermont Switchel Company commented below, I do add 1-2 tablespoons of molasses to bump up the electrolyte levels.
