Grammatically it should be… Winston tastes well, or goodLY.
Good is an adjective and can only modify a noun.
Since it is modifying ‘tastes’, a verb, it is incorrect (technically) – eventhough people speak that way all the time, and it even sounds better to our ear the wrong way than the right way.
Examples…
Yakov eats WELL – not good.
Chaim throws a football WELL – not good
Asher designs houses WELL – not good.
