Sima is a sweat mead that is an essential seasonal brew connected with the Finnish Vappu festival. It is usually spiced by adding both the flesh and rind of a lemon. During secondary fermentation raisins are added to control the amount of sugars and to act as an indicator of readiness for consumption — they will rise to the top of the bottle when the drink is ready. Sima is usually accompanied by munkkeja or Tippaleivät (donuts and other pastries). Mead is ready after 2-3 days.
