Recommended Variety of Cider Apple Tree

[terryc...@gmail.com]

I have a small orchard of mostly dwarf trees of eating apples, inherited when we bought the property and have been making cider from them for about 6 years. I want to replace an unsuccessful damson plum with another "cider" tree. The original trees are a mix of Granny Smith, Red Delicious and one Fameuse/Pommed de Neige. We have since been given a Ballerina and added a Cox's Orange Pipptn and Bramley's Seedling (at tleast that is what the tag said but the apples seem too sweet to be true to type).

Our climate is challenging being typical S.E. coast Australia mediteranian with warm/hot summers (30C) but as we are at 1000M and about 200km from the coast in the foothills of the Snowy Mountains, Winter is cold (-5C to +10C in the day) with Spring (i.e. now) likely to throw a -10C frost or strong winds just as blossoms are setting).

A few specialist nurseries offer some common cider trees so I would value any opinions re what would work and which way to go.
