For a delicious, healthy, hot beverage try a cup of silver tea. It’s cheap too, unless you are in Sweden, were it reportedly fetches at least the same price as a cup of Earl Grey.
My other cabin is water access only and I don’t own a boat, so if I would run out of coffee and tea I couldn’t go to the store and get more. I found that I was just as happy with some spruce needles in my hot water or even just a cup of silver tea(hot water).
