Swedes, help me out here, please.

Is it Gotlandsdricke or Gotlandsdrika or Gotlandsdricka?  I’ve seen all 3 spellings.

depends on how many pints you’ve had…

AKA…
Gotlandsdricku

Probably just depends on where you were raised & how your family spelled/said it.
I think Finns & Norwegians call it sahti.

Your safest spelling is probably “Gotlandsdricke”.

Oh no!  Now I’ve got four ways to spell it?  Must have a homebrew to chill out.  I’ve actually been using the ‘safest’ one.
