Alright, gave them an earnest taste yesterday and last night. I didn't bother with the red wine yeast batch because I wanted to try the champagne yeast batch. The plain cider was good and I did enjoy it. It wasn't quite what I was expecting (I'm used to Angry Orchard, which I don't drink at all after trying it a looooong time ago) but once I wrapped my head around what I was drinking it was good.
Last night while enjoying a cigar with my neighbor I tried the batch made with berries in the primary ferment. I took a bottle for both him and I and I really enjoyed that one. It was very tasty, champagny, and just a touch of the berry notes in there. I'm very pleased with how this turned out.
The berry batch was 8oz of berries to 1 gallon. I think I'll do another batch but up it to 16oz of berries to see what that gets me. I also have some ale yeast I picked up when I bought my bottles that I'm going to try out. I also plan on taking a page form David's book and adding some turbinado sugar to the primary ferment for a plain batch of just cider and yeast. Three more batches are on the horizon... I just need to empty some bottles first
Congratulations! Cheers! Prost! Na zdrowie! (I'm German & Polish and my wife loves the Prost ritual where we click beers hard enough to slop them and prove we're not poisoning each other and keep eye contact while drinking or risk 7 years of bad sex.)
On a serious note, what berries? I'm kinda interested because I'm thinking of using my currants in either a cider or mead this year. Every year I fill a gallon bucket at least but struggle for a use and end up putting them in vodka or rum with other fruit. We krauts call it a rumtopf and while it's kinda good it's really just a hodgepodge of unused fruit.
Definitely try adding a lightly refined sugar. It adds complexity (which I like) and more booze (which I like). I figure if you're going to homebrew make something unique. Delicately sipping something in the 8-12abv just feels more rewarding than gulping a 4abv in my opinion.
Also consider trying a bottle of calvados, French apple brandy. Far better than the over-sweet German schnapps (though we keep apfelkorn for shots after fancy meals). It's spendy but will get the wheels turning on how far you could take the hobby.
