Methods and results
How BlindRank calculates the ranking.
The group result is calculated from the method chosen by the organizer. The options are score or ranking.
Overview
The organizer defines the method before the tasting. From there, all tasters evaluate the same wines under the same rule.
BlindRank does not try to decide which wine is better in absolute terms. It consolidates the table's evaluations and shows the group ranking for that tasting.
Score mode
In score mode, each taster assigns a score to each wine. The organizer chooses the scale. The current options are ★, 1–10, 20 pts or 100 pts.
The calculation starts with a simple average. BlindRank adds the scores for a wine and divides them by the number of valid evaluations.
Example
A wine received scores of 86, 88, 90 and 92 on the 100 point scale.
Result: (86 + 88 + 90 + 92) ÷ 4 = 89.
The final ranking orders wines by average, from highest result to lowest.
Ranking mode
In ranking mode, each taster orders the wines by personal preference. BlindRank transforms that order into a comparable score across all tasters.
A better position gives a wine a better aggregate score. The group ranking reflects the table's average preference, not only one person's first choice.
Example
In a tasting with 4 wines, one taster places wine #2 first and another places the same wine second.
BlindRank combines those positions with the remaining evaluations to calculate wine #2's final group placement.
Extreme exclusion
When enabled by the organizer, extreme exclusion removes the highest and lowest score for each wine before calculating the average.
In score mode, this means removing the highest and lowest score. In ranking mode, it means removing the highest and lowest point contribution for that wine.
Applied only with 5 or more tasters: the calculation removes two values, so BlindRank needs enough evaluations for the result to remain representative. With fewer than 5 valid evaluations, all scores stay in the calculation.
This can reduce the impact of scores far outside the table's pattern, especially in larger groups.
Example
A wine received scores of 70, 86, 88, 90 and 99.
With extreme exclusion, 70 and 99 are removed. Result: (86 + 88 + 90) ÷ 3 = 88.
If the group is too small for exclusion to make sense, use the simple average.
Ties and tiebreakers
The organizer can allow ties or ask for automatic tiebreakers. When tiebreakers are active, BlindRank applies cascading criteria until tied wines can be separated.
The criteria consider aggregate performance, consistency between tasters and the distribution of positions or scores. If there is still no meaningful difference, the tie can remain.
Important: tiebreakers exist to order very close results, not to change the central evaluation logic.
History
After the reveal, the tasting stays saved for later. The history helps compare evaluations, revisit labels and preserve the group's memory.
The record shows the result of that table, in that context. A new tasting with another group can produce a different ranking.
