For the most part, that’s the same thing for me as well. Arneis seems to be a variety that struggles to make interesting wine - or then it is a variety often vinified in a way that doesn’t really benefit the cultivar.
FWIW, here are some Arneis bottlings I’ve found to be more than just meh:
- Valfaccenda Arzigh (a serious and structured orange wine - can be quite heavy in warmer vintages, so concentrate on cooler years)
- Valfaccenda Arneis (sees a tiny bit of skin contact; if quite rich and textural but also quite nuanced and interesting for the variety)
- Val del Prete Luet (half of the grapes are macerated for a few days, adding a bit of depth and complexity)
- Matteo Correggia Arneis can be a pretty nondescript wine in its youth, but can age wonderfully for many years, becoming quite interesting in the process
- Ca du Russ di Sergio Marchesio Arneis (I remember this showing more depth and complexity than the often somewhat neutral variety usually brings to the table)
- Just like the Matteo Correggia version, also Angelo Negro’s Arneis benefits from at least a few years of extra age. It doesn’t become anything exceptional, but still much better than how it is soon after release. However, this wine can be also quite flabby in warmer vintages, so one needs to avoid them.
Also Vietti’s Arneis has also been pretty nice in some vintages. It also feels like a wine that could benefit from additional aging.
However, I’ve never been a big fan of Arneis. When it comes to Piedmontese whites, I’d rather go with Timorasso, Nascetta or Erbaluce.
