I am confused about the processes of maturation that occur from bottling.I recently transferred some 2006 red wine (Rondo,a German hybrid) from a 5litre glass demijohn to 75cl bottles.On sampling the wine on the immediate transfer,it was so disappointing that I was thinking of replacing these vines next year with more reliable whites.However,after just one week in a corked bottle stored vertically,the wine had improved so much that I would descibe it as very good,even excellent. So I wish to understand why flavour improves so markedly on bottling.Is it the inevitably introduced air ,although I thought best practise was to exclude it during transfer. Also,how do professionals judge the quality of their wine in bulk by sampling,if the flavour improves so much after bottling? Michael Michael
Much improved flavour from bottling

From what I have read before, your experience is more to do with bottle-shock than sudden maturation. Most people seem to agree that wine gets uppity on bottling and doesn't become ammenable once more until it has a chance to stretch its legs and pace around the bottle until it feels at home. Arguments rage as to why this is so. Usually a 2 month quarantine is recommended (if I remember rightly). It could be that yours improved markedly in the 1 week you waited.
Others will no doubt fill you in as to why bottle maturation works. They'll use much better words than I know :)
Thanks for the reply.The wine I described had been in a glass demijohn (tightly stoppered with a rubber bung) for three years,and I would have expected it to taste rather good by now.However on immediately pouring out a glass directly from the demijohn,the taste was dull and very disappointing after so much maturation in an inert 5litre vessel.The change after about a week in a corked bottle was nothing less than remarkable.Conventional wisdom suggests,as you do,that on bottling the taste should get worse for a while due to bottle shock.In my case the complete reverse has happened.

Perhaps you introduced a bit of oxygen when you bottled? Steve
I just read a neat article on judging wine and found that 87% of the time judges can't judge the same wine twice in a row and find similar results. So don't feel so bad. You are learning, as we all are. Young wines are hard to judge. I've been making wine for 15 years and I started by testing and tasting everything. Now I can taste when the grapes are ready and I can test for them too. The same is true of what you are doing in your carboys. Live, learn and enjoy. It's a great hobby. Maturation is an art not just a science. Consistent tempature, humidity, vibration in the storage area and laying the bottles on there side after 24 hours are all general rules that will give you good results. Best results? I'm not sure, but by your own admission you are learning. An excellent book on maturation to read is "The Way to Make Wine" by Sheridan Warrick. Sheridan uses meta bi-sulphite to stabilize wine in maturation and to hasten it's maturity.
Did you use a bottling bucket before bottling? IOW, did you rack into another container before bottling? If so, your probably just seeing the results of more degassing and addition on oxygen into the wine. I can't see how such a short time in the bottle would have any effect on the wine.
