AITA for telling my brother that we can share one glass of our grandfather’s wine, but it will be the only one he ever has?

I(30m) have 3 siblings including one sister(28f) and two brothers(29m and 35m). <br><br>For the past 2 years, my family has been preparing for my grandfather’s passing. He is suffering from dementia. His mental state has gotten worse and worse to the point where he only says “with.” When you talk to him. My family knows that he is dying already, we just don’t know when. <br><br>Before he was diagnosed with dementia, he told all of us that he would save a single bottle of wine that he bought on his and my grandmother’s wedding day, and that he wished to drink that bottle with his children and grandchildren at his grandchildren’s weddings. Sadly, only one of us was married, and that is me. My grandfather has never forgotten about the bottle of wine, so he moved it to his room for safe keeping. <br><br>Whenever my siblings and I are over at my parents’ house, we often stare at the bottle. We know that we may never get to drink it with my grandfather, but we still hoped. Soon enough, when he was diagnosed with dementia, we realized that it would never happen. <br><br>Well, all of us decided we wanted to drink the wine together as a family. A small celebration of his life, and a toast to him. My parents were not too happy about the idea, but they knew we would likely never get the chance anyway. <br><br>A few weeks ago, my grandfather passed away. We all knew it was coming, but that didn’t make it any less painful. My siblings and I were all very upset, but we still had the idea of drinking my grandfather’s wine. We told my mother, and she agreed. <br><br>Well, my brother had other ideas. He said that since he was the oldest grandchild, he deserved the bottle. My mother and I were horrified, and we immediately shot it down. He argued that it was what my grandfather wanted, and that he would drink the bottle on his wedding day. I asked him to tell me what his fiance thought about it, and he looked ashamed. <br><br>It’s no secret that my brother and his fiance do not get along. In fact, my family and I do not even know if they are still together. They fight almost all the time, and none of us are sure what happened to his proposal. <br><br>My brother had also asked my wife and I to not drink the wine at our wedding, which was before he got engaged. We agreed, knowing that my grandfather may still be alive at the time, but that didn’t happen. <br><br>My brother suggested we each have a glass, but I told him no. I told him that we could share one glass, and that would be it. So, what happened was that we each poured a little bit of wine into one glass, and then passed it around the table. <br><br>A few days after the funeral, my brother went to tell our uncle that we had opened his father’s bottle of wine. Our uncle was absolutely furious, and called my parents to yell at them. My mother got in trouble from her brother and sister, and my siblings and I got in trouble from our uncle. <br><br>AITA for giving my brother the option to share one glass of my grandfather’s wine?<br><br>Edit: Restructured para 4 for better understanding<br><br>Update: I am quite happy to see that the majority of you think I did the right thing. My family has given me a lot of flak, and I admit that I was a little upset. But all of your comments have cheered me up, and I want to thank you for that. <br><br>My wife and I have also talked things over, and we are going to tell my family at thanksgiving dinner tomorrow that we will be taking the bottle with us when we move. <br><br>Also, my grandfather was Italian, and the bottle of wine was a 1947 Chianti.
