You can easily remove the stems as well as crush the grapes by hand. For small batches of grapes, you can use something as simple as a potato masher to crush the grapes; just make sure it has been cleaned and sanitized first. If you are dealing with larger amounts of grapes it may be worth it to go ahead and invest in a grape crusher as this will speed the process along.

As previously mentioned, after the grapes have fermented for a few days, you will need to press the pulp in order to extract as much juice as possible. In the event you are making white whine, the grapes will need to be pressed directly after they have been crushed but before the first fermentation.

When working with fruit rather than concentrate you will also need to have a hydrometer on hand in order to assist you in controlling the sugar level. As you may recall, this essential in determining the alcohol level in the final wine so it is a step that must not be overlooked.

An acid test kit may also be helpful in controlling and monitoring the levels of acid that are present in your wine when you are using fruit rather than concentrate. When the acid level in the wine is too high, the resulting wine will typically have a taste that is too sour or sharp. If there is not enough acid; however, the wine may taste somewhat flat. An acid test kit will provide you with accurate readings and help you to determine whether you need to add water or acid blend for balance.
