Thanks this is exactly what I was looking for . 4 seemed too small and 8 too big. I settled on 5 oz hot sauce bottles for my first batch but I think I am going to switch to the 6 ounce like you have in the first pick .
Limoncello is a huge hit and it looks like I have to go into mass production lol.
Working on my other cellos. But so far none as good as lemon.
