You know that the alcohol evaporates at 78°C, don't you? ;)

I found out by accident, last winter, that plain Blossa starkvinsglögg just gets better if you put it in the back of a cupboard and forget about it for a couple of years 😹 It had lost that sharp edge it often has when new, so I bought 10 bottles - 5 for this winter, 5 for next, and will keep doing so.
