Good discussion!
I did my first hopped cider this season just gone. Apart from curiosity, and the fact that I have had some rather nice hopped ciders in the past, I really just wanted to work on ('sweet'-sour-bitter) flavour balancing. Toward the end of the Tasmanian apple season there are only dessert and cooking apples, as elsewhere I imagine, and once the Sturmers are finished, then there is little in the way of apple-sourced bitterness to be had straight from the trees.
This year I had some end of season Granny Smiths and some feral Croftons from the roadside. They made a good appley sour-sweet blend and thought a bit of 'dry hopping' would make a good initial trial for 'bittering'.
After reading up a bit, I thought that either Cascade or Cintra would be good to try. I also remembered the fruity bitterness that Galaxy imparts to beers and decided to go with that for my initial foray considering the fruit being used. A planned risk.
Technique: 28 lt of juice 50:50 Granny Smith and Crofton inoculated with EC1118 and left to get into active primary fermentation. I put 50g of Galaxy hop pellets into a mesh 'sock' with a float attached and added to the ferment for 72hrs (+/- 15min :-)). I fished the sock (and float) out, being careful not to squeeze the 'teabag' too much. The primary fermentation was left to complete to dry before transfer and priming for conditioning in bottles.
Taste? Sharpness from the Granny Smith plus appliness from both Grannies and Croftons. Galaxy hops added a complementary fruity note but also a satisfying and thirst quenching slight bitter edge. The limited time on hops ensured that it did not overpower the underlying apple cider flavour.
The neighbours, so far, think that it is great. Fellow ciderists, down at the social club, had varying opinions, depending on their partiality to hops in general. Overall, and after a concentrated appraisal, they thought it was successful. Me too!
After more thought, I would do this again if the appropriate apple combo presented itself. I would probably try dry hopping with our local Cascade hops for a different flavour profile next time however. If there was a surfeit of dessert apples at some stage next season I might also try fermenting on the hops from start to finish to get a feel for that technique too.
