Yesterday spent several hours with GF2011 ferments which are coming along a treat despite some early issues. Needed all racking off the tartrate crystals following cold stabilistion - warming up here now. Blended some Merlot and Sangiovese to make my version of a "SuperTuscan". Really very good indeed at the moment and a lot of improvement still to do.Simon

Also, if the wine is left to warm back up, will the crystals dissolve back into the wine?

You can of course add the acid back if needed - but in red wine use tartaric acid rather than citric (can causes issues in wine that has gone through MLF). I avoid Malic altogether due to the harsh flavour.
I have found that some of the crystals can dissolve back into the wine if the temperature rises, but certainly not all and I have not had any problems with precipitation once I have added back acid, probably due to the overall level being insufficient to cause the crystals to form, but it might just be a combination of luck and staorage conditions.Simon

Thanks for the explanation Simon, I think I need to read up a bit more on the subject. Most of my wine is bulk ageing in an unheated garage at present and nearly everything has signs of crystals at the bottom.
I am not planning on racking my red GF2011 wines for another couple of months when things should be a lot warmer. I have racked and bottled a gallon of the Trebbiano after Duffbeer said he had already started drinking his

Just ticking over - cleaned bottles, stabilised a WE Ltd Ed kit, racked a Paklabs Pinot Grigio.
Things are mounting up due to lack of time - MUST get some oak in the GF2011 wines soon.Pete the Instructor

Blackberry, currant, red grape juice is wearing-off its campden hangover. Then I'll pitch R56 tonight. As frosts seem they maybe over, it's time for TC, so I can get the cider vinegar working its first batch in 10 days time... Spring!Now bottling 20DJs of 2013 red and making room to rack 5 carboys of 2014 red to the DJs where they can wait for another winter.

Racked the Selection Estate New Zealand Marlborough Sauvignon Blanc as it was down to SG.999 and a little late to be getting under airlock.
Also tested the SG of a Beaverdale Merlot kit that I added some GF2011 grape skins to. I think 1kg of skins is way too much in a 6 bottle kit as although the flavour is great, the tannins and acid are very high. It should be good though.............in maybe a couple of years time

Well if I can get my finger out of my backside, I would like to be able to get round to firing up the 2 X chocolate raspberry port kits I got before crimbo....... Plus there's about 18 gallons of mead that needs sampling, ready for blending and any back sweetening/acid necessary.......
But I'll probably end up doing bog all and watching the rugby (hopefully, this time, without the bloody air ambulance landing in the school carpark behind us just after kick off - near neighbours sticking knives into each other again......)Women will never be equal to men until they can walk down the street with a bald head and a beer gut, and still think they are sexy.

Hi Rob, I'm a great fan of the Selection NZ, I have done 3 so far and there's another on the shelf for doing soon. I'm getting so possessive about it that I'm making sure I've got some, well quite a lot, of others getting to drinking stage at the same time. It's great to have chums, it's great to have chums to share your wine, it's great to have chums to share and appreciate your wine, but the really good stuff is wasted on them!
PS the three I did got down to 0.994Now bottling 20DJs of 2013 red and making room to rack 5 carboys of 2014 red to the DJs where they can wait for another winter.
