I work in an old an old school restaurant and Make about 100+ butter sauces a night. If you can think of it I have probably made it into a butter sauce.
The important thing is to reduce the wine or liquid down enough. It depends on the size batch your making. If you reduce the liquid to far it will not allow the butter to emusify and eventually break.
also most will make butter sauce on low heat and one piece at a time this is a bad technique. Use high heat and all your butter at once. This will allow your liquid to keep reducing while cooking and allow the butter to slowly emulsify into the wine.
For example here is a simple but great recipe.
1oz key lime juice
2oz white wine
1# unsalted butter
Salt to taste or base of your choice.
1 jalapeño
Slice jalapeño and add wine and juice, place
On high and reduce by about 2/3 once this add the full 1# butter cubbed and continue
To stir. Adjust seasoning and once butter has just about melted remove from heat then strain. This will result in a nice thick key lime jalapeño Beurre blanc.
This is the best technique also once you get comfortable you don't need to stir constantly and you can even let butter reduce to a certain point without breaking.
