Fermenattion

[Del]

HI all,

I'm  new here and apologies if my questions has been asked already, I started my first apple cider fermentation after reading book of "Craft Cider by Andrew Leah" and some video in youtube.First I bought a 5 liters demojohn and juice from our local shop here.I started fermentation with S.g of 1045 and Ph of 3.5 (using ph strips) and the temp. in the room is between 8-12 Celsious and 20-25 during the whole day but after 6 days now I can't see any foam at the top of the juice and no air bubble in Fermenter air lock but I can few lees at the bottom.What would be the problem? why I can't see any foamy bubbles in my cider? is it due to room temperature?..I dindn't open it, as I just visually check it everyday.

cheers,

Del

What sort of juice are you using?  Who made it? What sort of yeast are you using? Have you seen any signs of fermentation at all?What was your original gravity (SG) and what is it now? Where are you based?  There are no ripe apples in the northern hemisphere yet except from last season cold store.

Hi Andrew and Vince,

I'm based in Queensland Australia  and it's winter now ( 46-77 degree farenheight)

I did not press the apple as I bought first  apple JUice  in  our Local shop here in our place

MY original Sg is 1045 but now it's 1005 (after 7 days)

I can't see any fermentation sign (i.e foamy bubbles)  except that the color is dark yellow with few lees at the bottom

The yeast that I'm using is Mangrove Jacks Cider yeast -M02- (54-82 F ferment with this range)

The Nutritional Information of my apple juice are,     (per 250ml serving)

Sodium 10mg

Vit c-25mg

Reconstituted Apple Juice:99.7%

Regards,

Well you’re in a very simple situation. Your fermentation is over and at sg 1.005 you’re entering the maturation phase. Not all ciders show a lot of foam as they ferment and you may have had a slight leak around the airlock seal so you missed the visual signs. Especially since your original juice was clarified ex concentrate. 

Entirely up to you how you play it from now on! My book should help. Good luck. 

Andrew

Hi Del

I am in Oz but a bit colder than you (Snowy Mountains). One of the best "store bought" juices if you have it up there (sometimes stocked by Woolies) is Presafruit Pink Lady. It makes quite a good "single variety" cider using S04 or DV47 yeast. I have a small orchard of eight trees, but sometimes the frost and snow trashes things in Spring so my fall-back is Summer Snow juice from Belview Orchards from Officer in West Gippsland, Victoria (Google them). They have single variety juices and I will sometimes do a batch of 50% Pink Lady, plus Royal Gala Granny Smith or Golden Delicious. It is a bit more expensive than el-cheapo supermarket juice and has to be bought on-line at around $50 for 6x2 litre bottles, delivered. Sometimes the el-cheapo no-name supermarket juice is refined and filtered so much that there are no solids left to help generate the primary fermentation foam. Cheers... hope this helps!
