I'm quite often asked, "What is the best serving temperature for our wines?" The broad answer is to serve at whatever temperature you prefer, but I can give you some guidelines to help.
Our Rosés are very well made so they should be enjoyable at up to room temperature without showing any faults. I suggest serving quite cool, somewhere between 8 and 12 C. as this suits most tastes. However, the aroma of the wine may not be as full and fruity as it becomes when the wine warms up. Likewise the taste can move towards being somewhat less dry and more fruity as the wine warms, a nice effect, quite pronounced in Rosés. Stemmed glasses will prevent the wine warming quickly as will chilling the glasses first.
And what about ice? Controversial for some, I have no problem with it, especially if serving Rosé on a warm day. A nice touch can be to make up the ice in advance from bottled water, perhaps selecting a French still water to make ice for French wines. (The same applies to ice with good Scotch Whisky - best use Scottish water for a soft taste). Ordinary tap water ice is fine for the ice bucket to keep the wine cool, but not too cold.
Hope this helps!
