We will be spending a month in Europe in June/July, mainly in Switzerland, Austria and Slovenia. As this is the first time we have travelled since becoming vegan, I had planned to take travel packs of soy milk with us but haven't been able to find anything smaller than 1 litre. I know there are soy milk powders, but I wonder whether it might be easiest to just buy long life soy milk in supermarkets as we go. Does anyone know how easy it is to buy in these countries, or if there are any alternative options? With thanks.
I don't live in these countries but I live in Germany. I don't think you have to worry.. there should be soy milk in most of the stores (at least in Switzerland and Austria). I don't know about Slovenia. In Germany you can buy it in almost every store so I think it's similiar in those 2 countries :)
There is soy milk (almost always GMO-free) in virtually every supermarket in Europe. You don't have to bring your own.
There also starting to have other plant-based options like almond and rice in mainstream stores.
You should be fine.
