You, as a wine maker, might have to develop the art of testing a wine, so as to determine whether it's completely fermented and prepared to open. Should youn't have enough time to futz with funneling wine from 1 bottle into another, think about purchasing a Vacu-Vin. For people who are learning about wine it's potentially invaluable allowing you to assess many unique bottles without needing to open and consume all of them in a brief time period.
