It is often the case that a vigorous ferment will overcome the fermentation lock as yours did. A good idea for the future is to cut a plastic fizzing drinks bottle in half and then you can put it over the top of the fermentation lock in case of a minor eruption. It is an extremely good idea to locate your fermenting musts in an area that is not surrounded by your favourite furnishings. There will always be a situation sooner or later where an accident will occur and you will have a spoiling result --- especially with red wine! if you have a utilities room that is not overheated that might be a good place.beware of having your fermenting must in a place which it too warm. Do follow the recommended temperature in your instructions -- cooler is better than warmer---- it will just take longer to ferment out if it is cooler
You don't say whether this is your first kit (we all had a first time you know) and I expect that you are wanting to drink this wine this Christmas time. The kit is at the cheaper end of the kit wines available at about £18 I would really strongly suggest that next time you go up one level to round about £30/£40 per kit -- Beaverdale, Grande Maison Reserve and so on. You will be amazed at the increased quality in the end product especially in red wine kits. The latest red wine kit that I bought in UK cost me £100 for a 23 litre/5 gallon(imp) kit!
Now to check the state of your wine for having cleared. The easiest way is to siphon off just a glassful ( wineglass not pint glass) and examine it against a suitable lit background. Do not put your siphon tube all the way to the bottom of your carboy. If it is clear then you can bottle it for imminent consumption. It is often difficult to see through red wines in 5 gallon carboys ( a little laser will do it). I am assuming that you have added finings and had not been moving the carboy around That being the case almost certainly the wine will be clear. If it hasn't cleared then keep it in a cool place for another couple of weeks ( I would suggest also that you top it up with some similar wine also) Could you tell me what the final Specific gravity is? Are you able to check this? If not it doesn't matter and don't worry about it.
Do you have a second carboy of the same size? I hope so because it is a very good idea to rack from the existing carboy into the clean one -- carefully ensuring that none of the lees at the bottom of your carboy are disturbed and go into the new vessel. Just be very careful and don't worry about wasting a bit of your wine. This helps a lot when you are bottling so that then you don't have to worry about the lees any more Then you can do one of two things
1 Bottle, cork and label and start to drink as and when.
or
- Dissolve a couple of crushed campden tablets in a little of the wine and then add to the new carboy.. Top up the new carboy with wine of a similar type ( from the supermarket!) to about 1 inch of the bung and let it sit for another month before bottling --- and then bottle it. It will be much better!
Hope that helps. It is a bit brief and basic.
