SIMA = DRINK
"Sima is (...) a sweet sparkling brew that is mainly seasonal and connected with the Finnish Vappu (May Day) festival." (Wikipedia)
The secret:
The right yeast to sugar ratio.

That's why:
C6H12O6 = 2C2H5OH + 2CO2
In other words:
Fungi (yeast) consume sugar and turn it
into alcohol and gas.

Resulting a conflict between fizzyness and sweetness:

More yeast causes less sweet but more fizzy drink, and vice versa.

orange: upper/lower quartile

N=9
Commercial
sima
Generally, Home-made 1 and 2 were
equally good
Both of them stand on the first and second rank. Also, somebody didn't like them at all...

Home-made 3 was ranked as No3, while

Commercial drink was the
least favourite
for us.
Evaluation:
- Personal impressions, verbal evaluation
- Ranking the products from 1 (best) to 4 (worst)

Results:
Word cloud:
The most frequent descriptive words. "The clouds give greater prominence to words that appear more frequently in the source" (wordle.com)

Boxplot:
showing the medians and max/min values of evaluations.
Blind test
P.a.P
3 different
home-made
drinks (similar recipe but personal yeast usage;
Without added color, preservatives and flavour enhancers
1 commercial

"Marlin Perinteinen Sima"
With added color,
preservatives,
flavour enhancers
9 tasters
, mostly experienced sima drinkers.
The method:
Relaxed outdoor tasting
The final ranking
Less yeast, therefore more sweetness and less bubbles produced.
Yeasty taste, good fizziness, therefore less sweetness.
A little yeasty yet satisfying drink.
Perhaps a bit too much yeast?
This had probably nothing to do with yeast and fermentation ..
