Display value with highest average score

Hi holywasabi 

These days, I would recommend using the INDEX function to return a value with a given rank where the ranking is based on multiple values. In this case, it appears that you need Wine Name to be ranked first based on [score (average)] then based on Wine Name itself (ascending lexicographic ordering).

Here is how you could write the measures. The only difference between them is the WineRank variable which should be set to the desired rank.

wine name (wine score (average) top-1) = 
VAR WineRank = 1 -- Change to desired rank
VAR WineScore =
    ADDCOLUMNS (
        FILTER (
            VALUES ( wine_fact[Wine Name] ),
            CALCULATE ( COUNTROWS ( wine_fact ) ) > 1
        ),
        "@Score", [score (average)]
    )
VAR WineResult =
    SELECTCOLUMNS (
        INDEX (
            WineRank,
            WineScore,
            -- For equal scores, ties are broken using Wine Name (ascending lexicographic ordering)
            ORDERBY ( [@Score], DESC, wine_fact[Wine Name], ASC )
        ),
        "@WineResult", wine_fact[Wine Name]
    )
RETURN
    WineResult

wine name (wine score (average) top-2) = 
VAR WineRank = 2 -- Change to desired rank
VAR WineScore =
    ADDCOLUMNS (
        FILTER (
            VALUES ( wine_fact[Wine Name] ),
            CALCULATE ( COUNTROWS ( wine_fact ) ) > 1
        ),
        "@Score", [score (average)]
    )
VAR WineResult =
    SELECTCOLUMNS (
        INDEX (
            WineRank,
            WineScore,
            -- For equal scores, ties are broken using Wine Name (ascending lexicographic ordering)
            ORDERBY ( [@Score], DESC, wine_fact[Wine Name], ASC )
        ),
        "@WineResult", wine_fact[Wine Name]
    )
RETURN
    WineResult

Does this work for you?
