I rarely drink fruit juice due to the high sugar content however my favourite would be fresh pineapple juice, followed by FRESH orange juice.
I would make this myself as do not like the bought juices, and the taste of a fresh one is lovely.
I also like watermelon put through my juicer, which I have not used now for years!
We buy 5 flavours of fruit juice from Aldi, in the 2 litre bottles. My favourite of the 5 is the: Multi Vitamin Juice. I only have it on my cereal every
morning, & my husband has a glass of juice when he has his egg on toast for breakfast, about once a week.
PS: I never drink fresh fruit juice at home, but we ordered some in Bali, with our meals last month, & my favourite was mango. One of the ones my husband bought was a pineapple 1, but it was tasteless. I liked the mixed fruit ones the best.
I love carrot juice with apple, orange , celery , whatever -if we are talking fresh juice.
If we are staying in a motel, or I am in hospital , that offers juice I always have tomato juice. I love it. I have been disappointed many times because some tomato juice is too sweet and not what my mouth expects.
